Icebox Cookies - cooking recipe

Ingredients

1 c. butter
2 c. brown sugar
1/2 tsp. cream of tartar
2 large eggs
3 c. flour
1/2 tsp. soda
nuts, chopped very fine (pecans are the favorite)

Preparation

Mix well and divide into 3 or 4 parts.
Form into long roll and let stand until hard (refrigerator).
Slice into thin slices; bake 10 to 12 minutes at 350\u00b0.
Remove from pan while warm to avoid breaking.
Will keep indefinitely.
I like keeping rolls in freezer to bake as needed.
Been making (mother's helper) since 10 years old.
