Butter Tarts

Mom's recipe. Bring a napkin. 

3-4 tbsp. butter 
1 c. packed brown sugar (brown not yellow) 

1 egg 

1/4 tsp. salt 

A handful of raisins 1/4 to 1/3 c. 

A handful of chopped walnuts 1/4 to 1/3 c. Don't chop too fine, you want a bit of crunch. 

1 tsp. vanilla 

12 tart shells 

Cream together the butter a sugar. They just need to be combined, not beaten. Add egg, salt and vanilla and mix well. Fold in walnuts and raisins. Spoon into the prepared tart shells. 

Bake 450° F on a low rack for 8 minutes. The pastry should be cooked, the tarts browned on top and the filling a bit runny.
