Grains
have been the staple foods of many civilisations for thousands of years.
Wheat, barley, oats and rye in Europe, maize in America, quinoa in
South America, rice in the East, and millet in Africa.
Nutrition
Cereals
are seeds of plants, usually members of the grass family but there are
a few exceptions. They are annuals, that is they have to be planted
every year and at the end of the summer, when they have produced ripe seeds,
they die down. Like all seeds, cereals are very nutritious because they
contain all the nutrients the embryo plant needs to start growing. Unrefined
cereals are valuable sources of proteins, carbohydrates, B vitamins and
also contain some fat, iron, vitamin E and trace minerals and are a very
good source of fibre in the diet. Some cereals (wheat, barley, rye and
oats) contain the protein gluten, which is essential for leavened bread-making.
Without sufficient gluten, bread will not rise. People suffering from gluten
intolerance or coeliac disease must avoid any cereal containing gluten.
In some parts of the world unleavened (unrisen) bread is eaten or the staple
cereal is made into noodles or pasta. They are usually cheap to buy and
are a valuable source of variety in the vegetarian diet.
Storage
Keep in airtight containers in a cool, dark, dry place. Whole grains can
be stored for up to 2 years; flaked, cracked grains and flours should be
used within 2-3 months of purchase.
Sprouting
Whole
grains can be sprouted, which greatly enhances their nutritional
value, e.g. wheat grains, raw buckwheat and barley.
Cooking
Cereals
can be used in other ways, besides being ground into flour for
bread, cakes etc. Whole grains can be added to stews and casseroles,
or
cooked until soft. Cracked or kibbled grains are cut or broken pieces
of whole grains e.g. kibbled wheat and bulgur wheat. Meal, a
coarse
kind of
flour, can be used to make porridge, thicken soups or mixed with
wheat flour to add interesting flavours and textures to ordinary
breads,
biscuits, muffins etc. (see Recipes
Index)
Whole grains should be washed
thoroughly. Boil the required amount of water, add the washed grain,
stir once, put a tight-fitting lid on the pan and simmer for the required
cooking time or until the liquid is absorbed. Turn off the heat and
leave to stand for 5 minutes before removing the lid.
Barley
Barley grows in a wider variety of climatic conditions than any other cereal.
It used to be a very important source of direct human food, but its use
has diminished over the last 250 years, replaced by wheat, and it is now
used almost exclusively as animal feed or for making beer and whisky. It
contains gluten, so barley flour can be made into bread. More usually found
in the shops as whole or pot barley, or polished pearl barley, it is also
possible to buy barley flakes or kernels. The whole barley is more nutritious
with 100g providing 10.5g protein, 2.1g fat, 69.3g carbohydrate, 4g fibre,
50mg folic acid, 6mg iron and 50mg calcium. It can be cooked on its own
(1:3 parts water for 45-60 minutes) as a pleasant alternative to rice,
pasta or potatoes, or added to stews. Malt extract is made from sprouted
barley grains.
Buckwheat
(gluten free)
Buckwheat is not a true cereal as it is not a member of the grass family,
instead being related to sorrels and docks. If you look at docks closely,
you can see that the seeds, though smaller, have the same distinctive triangular
shape. Buckwheat, a native of central Asia, is now grown in Europe, N America
and the former USSR countries, but it is still not widely used in Britain.
100g of buckwheat provides 11.7g protein, 3.9mg iron and it is very high
in calcium with 114mg per 100g. Available raw the seeds are greenish-pink,
or roasted (known as kasha) the seeds are darker reddish-brown. It can
be cooked (1:2 parts water for 6 minutes, leave to stand for 6 minutes)
and served like rice or you can add it to stews and casseroles. Buckwheat
flour can be added to cakes, muffins, pancakes etc. where it imparts a
distinctive flavour. Look out too for buckwheat spaghetti, soba.
Corn or Maize
(gluten free)
Maize is the principal food plant of America and was unknown in other parts
of the world until Columbus reached America in 1492. It was grown by the
Maya, Inca and Aztec civilisations, and by various North American Indian
tribes and now has spread to Canada, USSR, Italy, Spain, Egypt, India and
South Africa. It is used for human food, animal feed and as a source of
raw materials for industry. 100g maize gives 9g protein. Fresh maize is
often available (sweet corn, corn on the cob) but remember that nutritional
values will be lower because less concentrated. We most often see maize
as cornflakes or popcorn, but cornmeal or polenta is available and can
be added to soup, pancakes, muffins etc. Tortillas are made from maize
meal, as are quite a lot of snack foods. Do not confuse cornmeal with highly
refined corn starch/flour, used for thickening.
Millet (gluten
free)
Millet is the name applied to a variety of grasses first cultivated in
Asia or Africa. It is a staple crop in Africa because it is drought resistant
and keeps well. 100g millet provides 9.9g protein, and 6.8mg iron (higher
than other cereals). Millet makes a delicious alternative to rice but the
tiny seeds need to be cracked before they will absorb water easily, so
they should be first sauteed with a little vegetable oil for 2-3 minutes
until some are seen to crack, then add water with care (1:3 parts), bring
to the boil and simmer for 15-20 minutes until fluffy. Millet flakes can
be made into porridge or added to muesli and millet flour is available,
sometimes also made into pasta.
Oats
Oats are thought to have originated in Western Europe and may originally
have appeared as a weed in barley and so got spread with the barley. They're
now grown in many parts of the world including N W Europe, the former USSR
countries, North America, Canada, Australia and China. Used mostly as animal
feed, they are very nutritious. In fact, as they are usually inexpensive
to buy, they can be a real boon to people trying to get a good diet on
a low budget. 100g oats gives 13g protein, 55mg calcium (more than any
other cereal except buckwheat), and 4.6mg iron. Available as groats (whole
grains with the husks removed) but more usually as various grades of oatmeal,
rolled oats or jumbo oat flakes. Oat groats need cooking for 45 minutes
in 1:3 parts water. All forms can be used to make porridge, combined with
ground nuts to make a roast or added to stews. Oatmeal is low in gluten
so can't be used to make a loaf, but can be mixed with wheat flour to add
flavour and texture to bread, muffins, pancakes etc.
Quinoa (gluten
free)
Quinoa is an ancient crop which fed the Central American Aztec Indians
for thousands of years, and which has recently been cultivated in Britain.
Unlike most grains, it does not belong to the grass family, but is a relative
of the garden weed called Fat Hen. It is very nutritious, containing between
13-14% protein with a good amino acid composition but has no gluten so
it cannot be used for breadmaking. Instead, it is cooked for 15 minutes
in 1:3 parts water and served as a side dish or may be used in risotto,
pilaff, vegetable stuffings etc.
Rice (gluten-free)
Rice is one of the world's most important crops. It originated in Asia
but is now grown throughout the humid, sub-tropical regions. It differs
from most other cereals in requiring land that is submerged in water to
grow, though some varieties do grow in upland areas. Rice is a good source
of carbohydrate but doesn't have quite as much protein as some other cereals
(6.5g per 100g). Unpolished rice (i.e. wholegrain/brown rice) is a good
source of B vitamins too. There are three basic kinds in culinary terms:
long, medium and short grain. Long used traditionally in savoury dishes,
short in dessert cooking, although this varies across the globe and it
is really a matter of personal preference. Long wholegrain rice needs to
cook in 1:2 parts water for 35-40 minutes. Rice flour is available but
because of the lack of gluten, it cannot be used to make a yeasted loaf
but can be used for cakes, biscuits and pancakes. Rice flakes (brown and
white) can be added to muesli or made into a milk pudding or porridge.
Wild Rice
Wild rice is not a rice at all but an American grass used as an important
food by the Indians and early settlers. Difficulty in harvesting makes
it expensive, but the colour, a purplish black and its subtly nutty flavour
make it a good base for a special dish and it can be economically mixed
with other rices, but may need pre-cooking as it takes 45-50 minutes to
cook in 1:3 parts of water.
Rye
Rye is the least important cereal crop and is usually only grown where
conditions are relatively unfavourable and other cereals don't do well.
It probably originated in S W Asia, but the name occurs in Northern European
languages, which suggest early cultivation in that area. It is very hardy
and so grows in temperate and cool regions and at high altitudes, and is
very tolerant of poor soil fertility. It is the only cereal apart from
wheat and barley that has enough gluten to make a yeasted loaf, but it
has less gluten than wheat, so rye bread is denser. It is more usual to
mix rye flour with wheat flour. Rye grains should be cooked in 1:3 parts
water for 45-60 minutes. Kibbled rye is often added to granary-type loaves.
You can also add rye to stews and rye flakes are available, which can be
used in muesli. 100g of rye gives 9.4g protein.
Spelt
Spelt is closely related to common wheat, originating in the Middle East,
and has been popular for decades in Eastern Europe. Higher in protein than
wheat, it appears to have a different molecular structure, appearing to
cause less problems than wheat for some sufferers of grain allergies. It
has an intense nutty, wheaty flavour. The flour is excellent for breadmaking
and spelt pasta is becoming more widely available.
Wheat
This is the most familiar cereal used in Britain today, it is used for
bread, cakes, biscuits, pastry, breakfast cereals and pasta. All the present
varieties of wheat seem to be derived from a hybrid wild wheat that grew
in the Middle East 10,000 years ago. Over 30,000 varieties are said to
be in cultivation. Wheat can be grown in a very wide range of climatic
conditions but is most successful in temperate zones including the UK,
North America, Southern Russia and South West Australia.
Nutritionally, 100g whole wheat
provide 14g protein, 2.2g fat, 69.1g carbohydrate, 2.3g fibre, 3.1mg
iron, 36mg calcium. Wheat grains, also called wheat berries, can be
eaten whole, cooked in 1:3 parts of water for 40-60 minutes, they have
a satisfying, chewy texture. Cracked or kibbled wheat is the dried
whole grains cut by steel blades. Bulgur wheat, made from the whole
grains steamed before cracking, only needs rehydrating by soaking in
boiling water or stock. Couscous is the steamed, dried and cracked
grains of durum wheat and is more refined than bulgur. Soak in 2 parts
of water/stock to rehydrate, traditionally it is steamed after soaking.
Strong wheat flour (high gluten content) is required for yeasted breadmaking
and puff pastry. Plain flour is used for general cooking including
cakes and shortcrust pastry. Wheat flakes are used for porridge, muesli
and flapjacks. Wheat germ is an excellent source of nutrients, especially
vitamin E.
