That you knew you needed the acid in the lemon to keep the apples from browning suggests to me you know a thing or two.

To germanize this since you’re 80% there already all you need is to cook the red cabbage or Rhotkul in apple cider vinegar with some juniper berries.

Sunflower oil for the potatoes.

White vinegar and bacon with fresh parsley and you’ve gotten German Potato Salad. Dill if you’re into it. Typically garlic is a no, but I’m not the Stazi.

Bratwurst is the easy main. I wonder how healthy the chicken version is.

I normally make pork schnitzel with these sides.
