Here's one great recipe to keep you warm during these cold fall/winter days.
Ingredients
Onion 1p
Mushroom 800 g
Boletus (just few slices because it has very strong aroma)
Bouillon
Milk
Flour
Cream fresh
Bay leaf
Preparing
Chop one midsize onion. Place large pot on the fire. Pour some olive oil in, and put the onion in. Stir it till it become glassy and then add mushrooms. Mushrooms will release liquid.

Pour 2dl of milk into a cup and stir it with 2 tablespoons of flour. Mix it well and pour into the pot. Cook for another 5 minutes and its done.
