Mushroom gravy - Wigilijny

Ingredients:
          1 medium cut up onion
          Polish dry mushrooms
          butter
          about 2 tbs. of flour

Preparation:
1. Fry cut up onion in butter until it becomes translucent.

2. Add Polish dried mushrooms (first soak them for a few hours, then get as much of the water out as possible, next finely chopped them - I save this water, which I drain through the coffee filter, so I don't get any sand from my mushrooms)

[You can use canned mushrooms - finely chopped. Or you can use "Bulion grzybowy" which will give you the taste of the Polish dried mushrooms]

3. Add some water (or add saved water if you are using dry mushrooms). Simmer (about 30 min). Finally, add salt and pepper to taste.

4. Mix about 2 tbs. of flour with some water, then add slowly to this mixture so it does not have any lumps. Bring to boil.
