Made this last wk-end, it turned out quite good.
1 quart of beef broth
1 bottle of dark beer (I used an English mild)
1 head of cabbage, bottom removed, cut into strips
4 medium carrots, peeled and cut into slices
1 onion, quartered and cut into slices
1/2 tsp paprika
Beef bouillon cubes
salt and pepper to taste.
Put all ingredients into a stock pot, add just enough water so that you can see liquid (NOT above the ingredients), add one bouillon cube for each pint of water you add.
Bring to a boil, simmer for 60 minutes.
The taste of the beer was surprisingly obvious but not over the top.
Next time, I plan on adding some fire roasted tomatoes, should be nice!
