Put the soaked peas in cold, unsalted soaking water + cover and slowly cook until soft (pressure cooker). Blow hot through a sieve (or puree) + stir with a piece of butter + hot broth, salt, pepper or nutmeg to a smooth pulp.
Melt the butter or bacon, fry the onion rings in it until crispy + pour over the puree.
Sauté sauerkraut in the fat, loosen up with a fork, pour in 1 cup of white wine, add spices + slowly steam the cabbage until soft. Pour a little more wine if necessary. (Before serving, pull the drained pineapple cubes underneath).
For the pork knuckle, boil the water with the spices + vegetables (no salt), add the pork knuckles, they should be covered, + slowly cook until soft over a mild heat.
They are done when the meat separates easily from the bone. If you want, you can grill it too. A hearty men`s meal with pea puree + sauerkraut.
