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 and 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.
