Bring water to a boil in the bottom of a steamer.
Place the peeled beets on the steaming rack, cover, and simmer until the beets can be easily pierced with a sharp knife. This will be about 30 minutes for small beets and up to an hour for large ones.
8 small beets
Drain, allow the beets to cool slightly, then dice.
In a large saucepan, combine the olive oil, onion, curry powder, and salt. Toss until the onion is well-coated.
1 tablespoon olive oil, 1 medium onion, ¼ teaspoons Kosher salt, 2 teaspoons curry powder
Cook, covered, over low heat until the onion is soft but not browned, about 5 minutes.
Add the beets, cubed apple, and chicken stock.
1 apple, 2 cups low-sodium chicken stock
Simmer, covered, for 30 minutes or until the apple is soft.
Remove from heat and stir in the ground ginger.
½ teaspoon ground ginger
Transfer the mixture to a food processor and blend until very smooth.
