These things are 10/10. Put them on everything. The way I've been doing it: 1 whole onion cut into thin strips WITH the grain. Toss them around to get them seperated 2 jalepenos sliced Put them in the mason jar. Try to layer in the jalepenos and dont be afraid to squish it all in as tightly as possible to fit. Get the liquid to a boil. Half water, half vinegar, a bunch of salt (i just pour it in til there's an uncomfortably large amount in there). The second you see bubbles, shut it off and pour into jar til at the top. Try to get lid on without burning your hand. I usually store it upside down at first to make sure to get the top onions.
So good and so easy. Does take a bit of time (like any soup) but the steps themselves are short and simple. While I'm definitely curious about the rice part, we ended up making ramen noodles instead and just pouring the soup over them. https://www.allrecipes.com/recipe/8347912/scottish-cock-a-leekie-soup/
