Onion soup with black onion and dark beer

Onion soup with fermented black onion and brown beer. Onion soup used to be a bit of 'food for the poor'. Onions were cheap and you could still serve a delicious meal with them. We make a culinary onion soup with brown beer and black onion.

The bitterness of the beer is delicious with the sweetness of the black onions. Onions always have a bit of a sweet taste, especially if you let them caramelize gently. The anchovies give a salty taste to the soup.
