1. Melt shortening in a saucepan on the stove or in a large bowl in the microwave.
2. Cool slightly and add molasses and sugar. Mix well.
3. Whisk spices with two cups of flour and add to molasses mixture. Add remaining flour 2 cups at a time, along with ¼ cup of water.
4. Mix well and add enough remaining water so the dough is not crumbly.
5. Knead dough until smooth, shape into two discs, bag, and refrigerate overnight (or for a few days.)

*Add more water, a tablespoon at a time, if your dough is crumbly.

When ready to bake:

1. Line large baking sheets with parchment paper.
2. Roll dough 1/4″ thick and cut according to your template.
3. Bake at 325 F until firm but not too dark around the edges, about 12-15 minutes.
4. Cool completely before assembling your house.
