If the dough is too crumbly and doesn't hold together, add 1 tablespoon of water to the mixture and combine. For taping, Ina placed the cut out cookie dough hearts on parchment paper before baking. For taping, Ina drizzled each cookie with Vanilla Glaze (see below) and allowed the glaze to dry for 1 hour.
