Skinner was kind enough to provide us with the recipe, which you can read below or in her newsletter.
Borscht
Ingredients
3-4 cubes beef bouillon (depending how salty you like your soup)
1 q water
2 beets, washed and cubed
1 tbsp lard or 2 tbsp chopped beef fat
1 tbsp tomato paste
2 tbsp sauerkraut juice or vinegar
1/2 cabbage, shredded (can also use sauerkraut, if preferred)
1 large russet potato, cubed
Bay leaf, dill, thyme, to taste (and any other herbs you want)
salt and pepper
Instructions
Heat bouillon and water to a simmer, add beets, lard, tomato paste, and sauerkraut juice. Cover and simmer for 30-40 minutes or until > beets are tender
Remove beets and set aside. Add cabbage, cover, and simmer for 10 minutes.
Add potato, cover, and simmer for about another 15 minutes
In a separate pan, melt butter and add flour, cooking until just golden to remove the raw taste of the flour.
Add herbs to the flour mixture and cook for about 30 seconds, then add the whole mixture to your soup
Return soup to simmer, cover, turn off heat, and let sit for 15 minutes before serving
