this is a modified recipe of my brother Geert's French onion soup. Take a litre of water and cut three peeled vegetable onions into it. The pot must be set to full heat so that the aromas develop. It is best to take the largest pot you have in the household.
Then you open a bottle of dry white wine. When the water starts to boil with the onions, add 1/2 litre of the white wine.
Now you let the whole thing cook. You taste the soup sud with salt and pepper. After approx. ten minutes of cooking time, turn off the heat a little bit and add 3/4 l of milk.
Season again with salt and pepper,
