This is the recipe I usually make:
1 cup of sugar
1 cup of butter, left at room temperature for a few hours. Not melted in the microwave, this changes the consistency. My wife swears margarine is unhealthy, so I stopped using it. But, margarine tends to make a harder cookie if you find the dough too crumby for a gingerbread house. I definitely use butter for tree ornaments with no problem.
Beat the two together until fully combined.
For eating:
1 tsp of ground cloves
2 tsp of powdered ginger
1 tsp of cinnamon
1 tsp of salt
Mix well and fully combine again. I just leave this mixture in the mixing bowl.
For a gingerbread house, the dough is being used for it's aroma as much as anything. I double the ginger, cinnamon and cloves.
I use a 2cup Pyrex measuring cup for the next step.
2/3 c. hot strong coffee
2/3 c. molasses
Stir the molasses and coffee together until fully combined. Then add this to the butter, sugar and spice mixture and mix further.
In a separate mixing bowl, combine
4-3/4c regular flour
1 tsp. soda
1 tsp. soda
I like the dough better when I have sifted it.
I used to add a handful of flour at a time in the mixing bowl, then mix, then add more flour, until I had a solid dough. I now have a wonderful power mixer with a dough hook, and it works just fine to add a little flour at a time while leaving the dough mixing.
Wrap in saran or put the dough in an airtight container, then chill it for a few hours (though I usually leave it overnight in the fridge).
When ready to bake, take a chunk of dough and knead it until it isn't as stiff and feels uniform.
Set oven to 350.
I roll the dough out on Baker's Parchment - much easier to pick up and put on the cookie sheet. No need to grease the sheet either.
Depending in the thickness of the dough, 17 minutes is usually enough.
