Needs:
- half a pound of bubod
- a kilo of diket preferrably of the red variety
- a labba (or any wide space) to spread the rice to dry
- a gosi or any closed container
(Note: One of the most high-grade kind of bubod is available from the vendors of Abatan, Benguet. Don't try plastics as containers, they add a plasticky flavor.)
Ways:
Cook the kilo of diket with a little less water than you would cook an ordinay rice. Just after the boiling water has been absorbed (na-ilowagan), set aside the diket.
(Before continuing, tell everyone not to disturb you until everything as not to destroy the spirit of the tapey. The oldies even ask, 'Maid um-umtot' or 'No farting".)
Spread the diket on a labba covered with banana leaves (or just spread the diket around any open space) and wait until its a little bit dry. Crush the bobod into very fine powder. Then, spread the bobod evenly. (This is a crucial part - you have to do it very evenly. My mother told me that one of the secrets to a good tapey lies in the quality of the distribution of bobod in the diket).
Put this in your container and seal tightly. If you are in a cold place, put it in a warm location. (usually near the dalikan or in the corner of the house) Wait for at least 4-5 days, after which the tapey is now ready. Remember, the sweetness of the tapey decreases with time.
