For the fish in mustard sauce, boil 1/4 l vegetable soup and 1/4 l white wine.
Mix creme fraiche and mustard, add a little vegetable soup and mix. Then add the whole to the 1/2 l soup-wine mixture.
Season to taste with salt, pepper, sugar and lemon juice.
Add 1/2 cup of whipped cream and dill to taste.
Cut the fish (I usually use pangasius, but you can also use other types) into cubes and let it simmer for 5-10 minutes, depending on its size.
The fish in mustard sauce tastes delicious with noodles.
Bon appetite!
