Dried Mushroom Soup - Rasalas

This is the most disliked dish of my childhood, so I wanted to make it and try it as adult. It is a very old Lithuanian dish more common in the the Southern Region Dzūkija. It is made on Christmas Eve Kūčios.

The broth turned out beautifully, and everybody loved the soup. It kind of reminds me of pho or ramen broth, although is made very differently. I made the soup a night before the dinner, and it seemed weak to me, but the flavor was very rich the next day.
