PREPARING HOMINY
The cooking and “flowering” of the corn is not complicated, but it's a
little time-consuming until you are practiced in it. You can prepare a
large batch up until the final cooking and freeze what you don't use.
While the corn is usually cooked with nothing but water, there are some
exceptions, where salt, onion, and garlic are added.
Eight ounces of dried whole hominy, or large white corn kernels,
measures about 1 1/2 cups and when cooked will yield between 3 1/2 and 4
cups, depending on quality.
1/2 pound whole dried hominy, with pedicel (con cabeza) 1 1/2 rounded
teaspoons powdered lime (see below)
Put the whole hominy into an enamel or stainless-steel pot and add
enough cold water to come about 2 inches above the surface of the corn.
Set over medium heat. Dilute the powdered lime with about 1/2 cup cold
water and add to the pot through a fine strainer, pressing out the lumps
with a wooden spoon. The water will become slightly milky. Cook the corn
until it comes to a simmer (the skins of the kernels will now be bright
yellow) and continue cooking, covered, until the skin can easily be
slipped off the kernels-- about 20 minutes. Remove from the heat and set
aside to cool off. When the corn is cool enough to handle, drain and put
into cold water, rubbing the kernels through your hands until the skins
have been cleaned off. Skim off the skins and discard; rinse the corn
once more. With the tip of a paring knife or a strong thumbnail, remove
the pedicels.
When all the corn has been cleaned, add enough fresh water to come about
3 inches above the surface of the corn, cover, and bring to a fast
simmer. Continue cooking until the corn is tender and has opened up like
a cupped flower--about 1 1/2 to 2 hours, depending on how old the corn
is. When cooked, always reserve the cooking water and add it with the
corn to the soup.
You may use a pressure cooker for this last step. Bring up to pressure,
lower the heat, and cook slowly for about 30 minutes.
LIME
(Cal)
This chemically pure lime, calcium oxide, is used in the preparation of
dried corn for making tortilla and tamale dough. It is generally sold in
rocklike lumps of varying sizes. To use it in this state, break off a
piece about as large as a golf ball (once you have some experience you
can estimate more accurately) and crush it down as much as possible.
Sprinkle well with cold water. It will then start to slake, or burn as
the Mexicans say, and it does just that. It starts to crumble with a
slight sizzling noise, sending off a vapor. If you put your hand over
the bowl you are using, you can feel the heat emanating from it. When
the action has subsided, it is now slaked; stir again and pour the milky
liquid through a strainer into the pot with the corn and water. Take a
taste of the water; it should have a slightly acrid taste or, as the
Mexican expression goes, “grab your tongue.” If the water is very strong
and bitter, add more cold water to dilute the corn water. If it is too
weak, pour more water through the strainer containing the lime residue
and try again.
Since one usually buys lime by the pound at the very least, it can be
broken up into smaller pieces and stored in closed jars, but with time
it will naturally slake on its own with the natural moisture in the air.
It is still usable, although it will have broken down to a powder
containing some small lumps. When you add water to it for the nixtamal,
it will not burn.
Note: When handling lime, be careful not to get any near your eyes and
always use a non-corrodible container for diluting it.
