Walnuts (Russian Recipe)

Ingredients:
   1 cup sugar
   2 yolks
   1 egg
   250 grams butter
   3 cups all-purpose flour
   1 tsp. baking soda mixed with vinegar
   3 tbsp. sour cream
   1 (or more) can cooked, sweetened condensed milk
   walnuts

Step 1: Mix all the ingredients together, except for the last 2.
Step 2: When it's not soggy, but good dough, cut into little balls, and spread each out in the "walnut maker" holes.
Step 3: Wait for them to get light-brown on the edges, then take out and put in more.
Step 4: Do this until you're out of dough, then take the little shells and fill them with the sweetened condensed milk and half of them with both, that and walnuts.
Step 5: Then the ones with only sweetened condensed milk, combine with another that has a walnut in it.
Step 6: Do this to all of them.
Step 7: Enjoy!
