Bbc Beet Borscht (Buttermilk, Balsamic & Carrot)

Directions

1. 1
   Roast the beets: wash, trim and roast them whole in a foil packet at 375 degrees for about 45 minutes, or until very tender. When cool enough to handle, slip off skins and slice.
2. 2
   Heat the oil in a large skillet over medium heat and add the onion and carrots. Cook covered for around 15 minutes, stirring a few times, until fairly soft but not browned. Stir in the balsamic and continue cooking for about 5 more minutes, or until very soft. Stir in the brown sugar, adjusting quantity depending on sweetness of beets/carrots. (It should have a slight sweetness, but not taste like dessert.) Let cool slightly.
3. 3
   In a blender, puree the cooked vegetables with the canned beets and their liquid. It will probably take 3 or 4 batches, removing the puree to a big bowl as you go. (An immersion blender works fine for this, but I like the smoother puree you get in a blender.)
4. 4
   Whisk it all together with around 3/4-1 teaspoon salt and a few grinds of pepper, then the buttermilk. If it seems too thick, add a little more buttermilk. Add more salt if necessary (flavors mute a bit when cold, so don't under season.)
5. 5
   Chill in the fridge for a few hours; stir well and serve topped with a dollop of sour cream or creme fraiche, and a sprinkling of chopped chives.
6. 6
   *Note: roasted beets add depth of flavor, but for a quicker version - or when fresh aren't available - omit them and use 3 cans instead. It will still be delicious.
