Science
and Cooking: A Dialogue- Lecture 1- Harold McGee, Ferran Adria, José Andrés
On Food and
Cooking: the Science and Lore of the Kitchen is a book by Harold McGee, published by Scribner in
the United States in 1984 and revised extensively for a 2004 second edition. It
is published by Hodder & Stoughton in Britain under the title McGee on Food and Cooking: An Encyclopedia of
Kitchen Science, History and Culture.
The book provides a reference to the
scientific understanding and preparation of food. It has been described by Alton
Brown as "the Rosetta stone of the culinary world", Daniel Boulud
has called the book a "must for every cook who possesses an
inquiring mind", while Heston Blumenthal has stated it is "the
book that has had the greatest single impact on my cooking".
The book is simply interesting to amateur
foodies and culinary professionals. This is the serendipity principle. If you
prospect in a rich land, you will invariably find something of value. The
`lore' in the subtitle is not an afterthought. The book includes history,
linguistics and cooking practice in addition to simple science. In over 800
pages of densely packed narrative, one will invariably find something of
interest, especially since the book covers such a broad range of topics,
including:
1) Milk and Dairy
2) Eggs
3) Meat
4) Fish and Shellfish
5) Fruits and Vegetables
6) Seeds, Cereals, and Doughs
7) Sauces
8) Sugars and Chocolate
9) Alcohol (Wine, Beer, and Distilled Spirits)
10) Cooking Methods
11) Cooking Utensil Materials
12) `The Four Basic Food Molecules'
13) Basic Chemistry
The work is separated into sections that
focus on the ingredients, providing the structure for the author to speculate
on the history of foodstuffs and cookery, and the molecular characteristics of
food flavours, while the text is illustrated by charts, graphs, pictures, and
sidebar boxes with quotes from sources such as Brillat-Savarin and Plutarch.
The book advises on how to cook many things (e.g., for pasta use abundant water, avoid hard water, add salt and a
little oil to water, use slightly acidic water, with reasons and the science
behind everything, OFaC 2nd ed. p576) and includes a few historical recipes
(e.g., Fish or Meat Jelly, by Taillevent
in 1375, OFaC 2nd ed. p584), but no modern recipes as such.
You should be aware that this book is more
an encyclopedia than a recipe book or a collection of essays. If you're looking
for a fun discussion of food science, then Alton Brown's "I'm just here for the food" may be a
better choice. If you're looking for recipes that are optimized by principles
of food science, I'd recommend Shirley O. Corriher's "Cookwise." (Actually, I'd recommend both of those books anyway.) Some readers
may find "On Food and Cooking" a little bit too dense and technical
to read from cover to cover, but as a reference book, it's unmatched.
The second edition is a great improvement
over the first, and I'd strongly recommend it not only to new readers but to
anyone who read the first edition. (Just
the new section on fish makes this book worth purchasing.) This is really a
totally new book: it's been completely reorganized, new illustrations have been
added, and it's 66% longer than the old version. I'm guessing that the only
reason that this book has the same title is for marketing value: the first book
was very well known by cooks.

Complete Guide to Storing Fruits and Vegetables at Home
Find
out how to keep fruits and vegetables fresh.
*Culinary Physics Blog consulted
the U.S. Department of Agriculture (USDA), food scientists/technologist, professional
chefs, agriculturists, food manufacturers, and other experts—to establish these
storage guidelines. The first consideration was safety. But because you want
your food to be delicious, too, for some products, Culinary
Physics Blog chose the conservative storage time for optimum
freshness.
Eating more fruits and vegetables is a requirement for
every healthy eater. But when you buy more fresh produce, do you end up
throwing away more than you eat? You're not alone.
Based on U.S. Environmental Protection Agency research
(EPA), Americans throw away nearly 31.6 million tons of food every year. And a
recent University of Arizona study found that the average family tosses 1.28
pounds of food a day, for a total of 470 pounds a year. That's like throwing
away $700.
Storing fresh produce is a little more complicated than
you might think. If you want to prevent spoilage, certain foods shouldn't be
stored together at all, while others that we commonly keep in the fridge should
actually be left on the countertop. To keep your produce optimally fresh (and
cut down on food waste), use this guide (download
it for future reference- Storing Fruits and Vegetables).
Cold storage of fruits
and vegetables was used extensively by our ancestors to keep food after the
harvest season. In modern times, the year round availability of fresh produce
in the supermarket has reduced the use of home storage. However, even today
there are benefits of home storage, which make it a good alternative to buying
produce from the store. Most importantly, home gardeners often have excess
fruits and vegetables that cannot be consumed immediately but would store well.
Even those without gardens can buy food ‘in season’ when it is fresh and
inexpensive and then store it at home until a later date. Both these options
are cheaper than buying food in the winter when it is often quite expensive. In
addition, stored food harvested at peak maturity from the garden usually has
better flavor and a higher nutritional value.
Storing Fruits and Vegetables at Home
Use of Packing Materials
- Packing materials used in
storage perform several functions- insulation against fluctuating temperatures,
moisture retention, and reduction of disease transmission. In outdoor storages,
clean straw, dry leaves, corn stalks, hay, or sawdust are commonly used for
insulation. These materials may be readily available or can be purchased
relatively cheaply from local farms and garden centers. A slightly more
expensive alternative is peat moss. Use these materials for a single storage
season only, as they can become contaminated with molds and bacteria. They
often can be recycled as mulch in the garden. Moisture retention of produce is
usually achieved with moistened sand,
sawdust or peat moss. Plastic bags, lined boxes, crocks, metal cans with
liners, or plastic garbage cans are all items that retain moisture. Perforate
plastic bags or liners at regular intervals to allow air circulation and
prevent condensation and you can buy this easily at Amazon.com.
Vegetables requiring moist
storage should never be left directly exposed to air. Alternating layers of
produce with packing materials reduces disease transmission. Wrapping
individual items of produce with newspaper aids moisture retention and reduces
the possibility of cross-transfer of odors and disease.
Use of Refrigerator Storage - One of
the best ways to store small quantities of vegetables requiring cold or cool
moist conditions is to use an old or extra refrigerator. The amount of current
required to run a storage refrigerator is usually low because they are opened
infrequently and can be located in an out of the way, cool location. For best
storage, produce should be washed free
of soil and placed into plastic bags with 2 to 4 ¼” holes for ventilation.
The 5 or 10 pound bag size is usually most convenient for the average family. Vegetables
in plastic bags do not wilt nearly so rapidly as those stored openly in the
refrigerator.
Fruits and
vegetables add color, flavor, vitamins, minerals, and fiber to your diet, and
the quality of the produce you buy directly impacts the quality of the dishes
you cook with that produce. Who wants to eat a wilted salad or a dingy bowl of
fruit? Always seek out the best sources for produce. If you have a local
farmers’ market featuring seasonal produce, browse the stalls and choose what
looks best. You can plan a whole meal — or at least a memorable side dish —
around a really ripe carton of tomatoes and a dewy bin of fresh lettuce, or
what about those blushing peaches bursting with juice for dessert?
When choosing
and storing fruits and vegetables, whether from a farm stand or the
supermarket, a few rules apply across the board. Avoid fresh produce with brown spots or wrinkled skin or produce
that doesn’t look… well… fresh!
Here are a few other produce rules to live by:
1) Grapes: Fresh, ripe grapes are full and juicy
looking with a powdery bloom on the skin. Keep in the refrigerator for up to a
week.
2) Bananas: Eat them before they turn completely
brown. You can refrigerate them to slow down their ripening. Their peel
continues to darken in the refrigerator, but not their flesh.
3) Apples: Should be crisp and firm. Refrigerate
or store in a cool, dark place. Keep for several weeks. Some varieties keep for
several months. Apples release a gas that makes other fruits ripen more
quickly, so if you don’t want your fruit to ripen too fast, keep it away from
the apple bowl and don’t store it with apples in the refrigerator.
4) Pineapple: It doesn’t ripen after it’s picked and
is best if eaten within a few days of purchase. Keep at room temperature, away
from heat and sun, or refrigerate whole or cut up.
5) Avocados: These tropical delights should yield
just slightly to pressure when ripe. Keep at room temperature until fully
ripened. If you won’t eat them right away, refrigerate them to keep for several
more days.
6) Citrus fruits (such as lemons,
grapefruits, and oranges): When
refrigerated, citrus fruits (which don’t
ripen further after they’re picked and are relatively long-storage fruits)
keep for up to 3 weeks.
7) Cherries and berries: Keep refrigerated. For best flavor,
consume them the same day you purchase them. Cherries and berries get soft and
moldy quickly.
8) Tropical fruits: Mangoes, papaya, and kiwi should be
firm but yield slightly to pressure and should smell fruity. Store at room
temperature for more flavors, but refrigerate when they are ripe and then
return to room temperature before eating.
9) Unripe melons and tree fruits (such as
pears, peaches, and nectarines): Keep
at room temperature so that they can ripen and grow sweeter. After they’re
fully ripe, you can store them in the refrigerator for several more days.
Melons are ripe when they smell melon-y at the stem end. And if we haven’t
mentioned a fruit or vegetable you want to try… try it anyway! There are many
interesting produce options out there in the world. The more you taste, the
more you know.
10) Artichokes and asparagus: Refrigerate and use within 2 to 3 days
of purchase.
11) Cabbage: Keeps for 1 to 2 weeks in the
refrigerator.
12) Carrots: Best when firm, not rubbery, without a
lot of little roots growing all over them. They keep in the refrigerator for
several weeks.
13) Broccoli and cauliflower: Refrigerate and consume within a week.
14) Celery: Fresh celery is crisp and firm. Old
celery flops around like a rubber pencil. Keeps for 1 to 2 weeks in the
refrigerator.
15) Bell peppers: Store in the refrigerator for up to 2
weeks.
16) Corn: Refrigerate and use the same day of
purchase. After corn is picked, its sugar immediately begins converting to
starch, diminishing its sweetness.
17) Garlic: Garlic should feel firm, not soft, and
should be without any green sprouts. Once it sprouts, it turns bitter. Keep garlic at
room temperature, in a small bowl within reach of your food preparation area,
to encourage you to use the fresh stuff. Garlic will last longer in the
refrigerator, however, so if you don’t use it often, keep it chilled to inhibit
sprouting.
18) Onions, potatoes, shallots, and
hard-shelled winter squash (like acorn
and butternut): Keep at room temperature for several
weeks to a month. Store onions, potatoes, and winter squash in a cool, dry,
dark drawer or bin. Onions, shallots, and potatoes should be firm. If they are
soft or rubbery, they are past their prime.
19) Tomatoes: Store at room temperature for more
flavors. Keep in a cool, dark place or in a paper bag to ripen fully. Once
ripe, eat them right away. If you can’t, refrigerate them for two or
three more days, although this can compromise the texture, making them mealier.
Return them to room temperature before eating.
20) Cucumbers and eggplant: The skin should be firm, shiny, and
smooth, without soft brown spots. Keep for up to 1 week in the cold crisper drawer
of the refrigerator.
21) Leafy greens (beet tops, collards,
kale, mustard greens, and so on): Very
perishable. Refrigerate and consume within 1 to 2 days.
22) Spinach: Trim, rinse, and dry thoroughly before
storing in the refrigerator for 2 to 3 days.
23) Green beans: Refrigerate and use within 3 to 4 days
of purchase.
24) Salad greens: Rinse thoroughly, trim, and dry
completely before storing wrapped in paper towel or in plastic bags in the
refrigerator crisper drawer. They keep for 3 to 4 days. Do we have to tell you
not to buy slimy lettuce?
25) Summer squash (zucchini and yellow
squash): Store in
the refrigerator for up to a week.
26) Mushrooms: Store in a paper bag in the
refrigerator. Use within a week.
Remember when
harvesting your own produce for storage, or buying it locally in season, there
are certain guidelines to follow which assure maximum quality and minimum
spoilage of your stored food.
1. Harvest fruits and vegetables at
peak maturity or as near as possible.
2. Only use produce that is free
from all visible evidence of disease.
3. Do not pick any fruit or
vegetable that has severe insect damage.
4. Handle food carefully after
harvest so that it is not cut or bruised.
5. Leave an inch or more of stem on
most vegetables to reduce water loss and prevent infection.
6. Use late-maturing varieties
better suited to storage.
In general, use only the best food for storage.
Damaged food is more likely to suffer
mold and bacterial decay during storage and thus
should be used fresh, processed, or discarded.
Once
harvested, fruits and vegetables must be stored under proper conditions, the
most important of which are temperature and humidity. Each fruit or vegetable
has its own ideal set of conditions at which it will store most successfully
for the maximum length of time. These conditions can be classified into four
groups:
1. Vegetables which require cold
& moist conditions
2. Vegetables which require cool
& moist conditions
3. Vegetables which require cold
& dry conditions
4. Vegetables which require warm
& dry conditions
The charts or tables below list temperature and
humidity requirements for most vegetables. In addition to proper temperature
and humidity, all fruits and vegetables must be kept in a dark, aerated
environment. While most vegetables like moist conditions, standing water must
be avoided, as it will quickly lead to rot. Produce must not be allowed to
freeze and should be protected from animal pests such as mice. It is important
to remember that crops held in storage are still living plants, capable of
respiration and affected by their environment. The goal of storage is to keep
them in a dormant state.
One other note, fruits and vegetables should always
be stored separately. Fruits release ethylene, which speeds the ripening
process of vegetables. Fruits are also very susceptible to picking up the taste
of nearby vegetables.
