A small, plastic tool used for making Pecan tassies with. It’s solid plastic, shaped to fit exactly into a tart tin cup.
Instead of rolling out the pie dough to cut into individual rounds to fit into the tart tins, you put a small ball of dough in the bottom of each individual tart cup, flour the tassie press, and then press down hard on the ball of dough. It forces the dough up the sides of the tart cup, lining the cup with dough.
