The Annatto seeds are commonly ground into a paste
that is used to marinate meats. Annatto pastes generally contain garlic,
herbs, spices and vinegar.
Annatto
seeds are commonly used in three different ways in home cooking:
The whole seeds are ground
into a powder or paste and then combined with other spices and herbs and
used as a spice mixture. This mixture can then be applied to savory foods
and cooked as is or used as a marinade/rub or added to one. Annatto seeds
are surprisingly tough and hard to grind, an electric coffee
grinder works well. Use three to five second pulses for about 30 seconds
or until a fine powder is created.
The whole Annatto Seeds are
cooked in hot oil, or traditionally lard, for about ten minutes before being removed and then the
oil/fat is incorporated into foods. This method extracts the fat-soluble
compounds from the seeds and the resulting Annatto oil
will have a
pleasant red hue to
it. This oil can then be used in small quantities as a natural food
coloring, in larger amounts to add color and flavor to foods. The general
rule of thumb in making Annatto oil is to use twice the amount of any heat
stable oil as whole Annatto seeds and the seeds should be cooked in the hot oil
for at least five minutes or until the desired color is achieved. The
Annatto oil
will have an earthly flavor with hints of ginger and pepper.
The whole
seeds are steeped in a warm liquid for some time before they are
removed and discarded. This method removes mostly the water-soluble
compounds from the seeds and the steeping liquid takes on a yellowier hue. If the liquid
contains both water and fats such as in meat based stocks, both water and
fat soluble compounds maybe extracted along with their flavor and color
profiles.
This Annatto water can
then be used to color stocks, or cook yellow colored rice.
Like other spices Annatto
seeds should be stored in a cool dark place in an airtight container.
Stored correctly the seeds will remain fresh for at least one year.
