Kittywitch loves shortbread. Here's another one popular in our house, we can barely keep the jar full, and it makes a huge batch.
Finnish Butter Cookies
Five sticks of butter. Yes.
1 cup sugar
5 cups of flour
Raspberry jam, about a jar's worth
Preheat the oven to 350
Mix the butter, sugar, and flour into a dough, then roll the dough into cylinders.
Place the cylinders on cookie sheets, here's another time when baking parchment is your friend. Some of the jam will spill out of the cookies.
Take a chopstick and make a deep depression along the top of the cylinders, then bake for twenty minutes.
While the cookies are baking, melt the jam in a Pyrex cup in the microwave. If you have been baking for three hours, you will be tempted to poke the shiny, pretty red liquid. Do not do this.
After twenty minutes, pour the liquid jam into the depression along the top of the cookies.
Bake for another ten minutes to harden the jam.
When cool, cut the cookies diagonally so they make rows of little trapezoids.
You can substitute other preserves for the raspberry jam, but why would you want to?
