Irish Soda Bread

This is delicious warm from the oven, or toasted the next day.
Sift together in a bowl:

4 cups flour
1 tsp. baking soda
1 tsp. salt
1 Tbsp. sugar
3/4 cup currants (or raisins)

Add:

2 cups buttermilk (or 2 cups milk with 2 Tbsp. vinegar added)

Carefully mix together to form a dough. Knead for one minute but do not over work. Pat into a circle about 2 1/2 inches high on a greased cookie sheet. Cut a cross in the top about 1/2 inch deep. Bake in a 400 degree oven for 50 minutes.
