Using a Baking Table, craft the desired Dough. When preparing Foods at a Baking Table there is a chance to receive a Eloped Gingerbread Man.
Open the Baking Table and insert the Dough and wait. This will allow Bread Dough to Leaven. Note: Right-clicking on any Leavened Dough and selecting "Split" will split the Dough into 8x Sourdough Starters for use in other recipes.
Leavened Dough can now be placed in a lit Bread Oven to Bake. When baking Foods in a Bread Oven there is a chance for those Foods to become Animal Crackers instead.
