Dough you want to be mine? When Autumn Gates of Indianapolis, Indiana, offers up these lovable, squashable valentines, the answer is always a resounding, "Yes!"
Mix the flour, salt, and cream of tartar in a medium saucepan. In a separate bowl, mix the water and oil, then pour the liquid over the dry ingredients and stir. Cook over medium-low heat, stirring continuously, until the mixture holds together and gets too stiff to stir (it will stiffen even more as it cools), about 5 to 10 minutes. Let it cool, then knead it briefly. Halve the ball of clay, then knead food coloring into each half, a few drops at a time, until you reach the desired shade.
To make a big batch of valentines, start with 24 balls each of two dough colors, then press together one of each color to shape a two-color heart (use a cookie cutter as a mold if you like).
For each valentine, place the clay heart in a cellophane bag and add a card stock tag threaded onto a twist tie.
