The perfect thing for a hot summer night. Normal people will probably want to cut this in half or freeze some of: it freezes really well.
Peel and dice 3½ lbs of beets (to make 8 cups). Bring to simmer in pot with 8 cups water, ½ onion finely grated, 2-3 cloves garlic run through a garlic press and salt. When beets are cooked — not too soft — remove from heat and add sugar (2 TBL) and sour salt (½ tsp) to taste. Let cool. Mix with sour cream to serve and garnish with any of the following: diced boiled potatoes, diced cucumber, diced hard-boiled eggs or none of the above.
