Directions
Cook the beets
Place beets in a saucepan of boiling salted water, cover, and cook until tender and skins slip off easily, about 25 minutes.
Drain and let cool; slip off skins and cut into 1/4-inch dice.
Cover and refrigerate until chilled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beets
- Provide the main body, colour and earthy sweetness of the soup.
- Buttermilk
- Forms the tangy, creamy liquid base of the soup.
- Light sour cream
- Adds richness and body to the chilled buttermilk base.
- Green onions
- Add a sharp, fresh onion flavour to the soup.
- Cucumber
- Adds cool, crisp texture contrasting the soft beets.
- White vinegar
- Adds acidity that brightens the flavour and balances the sugar.
The step that matters
Cooking the beets until tender. Beets cooked until fully tender and then cooled slip easily and dice cleanly. Undercooked beets stay firm and bitter-tasting, while overcooking makes them mushy and can bleed colour into the soup.
