here is something I found on soup called "siemieniotka" which is prepared from hemp seed (siemie) with buckwheat groats (kasza gryczana). Hemp seeds used for this soup are hard to find anywhere outside Silesia and any other time except the Christmas season.
If you can't find hemp seeds, pot seeds will do. :-> My wife makes it each Christmas. She says it tastes horrible, but it wouldn't be Christmas without it. Her sons both love it so...
As my wife makes it it involves boiling the seeds, grinding them, boiling again, grinding again... repeat as many times as your patience allows. At the last boiling add some onion, then when it's done salt and pepper to taste. And she is Śląsk and only makes it at Christmas..
Oh, and throw away what's left of the seeds and the onions. Siemieniotka is the broth. And my wife tells me I shouldn't say "grind" like meat I should say "hit it and beat it" like a husband
instead of grinding i know it the way that you pound the seeds.
-you boil the seeds and then take a ridicilously large pot and put a handful of seeds in it - put a towel on the floor and put the pot on it. then take a wood hammer with a loooong handle >1m and start smashing the seeds till you see a white liquid coming out and the former black seeds turn into a smoosh of grey pulp.
- you take that and put it into a sieve and pour hot soup fond through it to extract the 'seed milk' do the same with the next patch of boiled seeds. -you can repeat that process for the whole lot if you are not tired of stomping. -balance the soup flavor with either more soup fond or some cream. -add boiled buckweed or if you dont have that rice to the soup. enjoy
it basicly has the similiar effect of making you more hungry while eating. something like a campari-orange cocktail a s a starter.
