Pour the tofu into a mixing bowl.

Flavor it with the vanilla by whisking it in (Skip if using vanilla-flavored tofu).

Thicken it by whisking in the confectioners sugar, tablespoon by tablespoon.

Same with the cornstarch-- add it and blend.

Add all of the lime juice and blend well.

Pour the mixture into an ungreased 8" pie pan (if crustless) or a premade 8" or 9" pie crust.

Bake at 375 for 30-35 minutes or until set.

Cool on a rack for 10-15 minutes first, then refrigerate for at least 4-6 hours before serving.
