Mom's Christmas Pudding

• 1 cup suet, finely chopped
  
• 1 cup currents 
• 1 cup molasses 
• 1 cup brown sugar 
• 3 eggs
• 3 cups flour 
• 1 cup sour milk* or buttermilk 
• 1 tsp baking soda 
• 1 tsp salt 
• 1/3 tsp cinnamon 
• 1/3 tsp cream of tartar

Directions

1. Combine all ingredients together in a large bowl.
2. Spoon into serving bowls, either one or two large ones, or in small individual serving cups. 

* - to make sour milk, set out the milk (that is at least 2% butterfat content) until it is at room temperature. Add 1 tablespoon of vinegar per cup of milk. Let stand for 15-20 minutes and it should start to curdle; i.e., lumps start to form in it. It is now ready to use.
