1 lb small fresh beet (all but 1-inch of stems removed
boiling salt water for cooking)
1/4 cup red wine vinegar
2 small onions (peeled, sliced & separated into rings)
1 tsp salt
1/2 tsp sugar
Place the beets in boiling, salted water. Reduce heat to low and simmer, partially covered for about 30 minutes or until tender. Add more water if necessary; the beets should be completely covered. Drain and cool.
Remove skins from beets. Slice into rounds or strips 1/4" thick. Combine vinegar, salt & sugar in a deep bowl & stir until sugar dissolves. Add beets & onions & stir to coat.
Marinate at room temperature for about 30 minutes, stirring every 10 minutes.
