Cut onions unpeeled(!) into two halves. Wash the carrots and cut into small pieces, dice 3 thick celery slices. Peel a clove of garlic, chop 1 leek stick (only the light green part of it), half a red pepper and 1 unpeeled washed potato.
Heat 2 tablespoons of vegetable oil in a saucepan and fry the onion halves with the cut surfaces facing downwards until they turn brown. Then add all the (root) vegetables, garlic and bell pepper pieces and fry all the ingredients for 3-4 minutes.
Add 1-2 tbsp dark miso paste and fry briefly. Deglaze the ingredients with 3 tbsp balsamic vinegar, 1-2 tbsp soy sauce and a dash of red wine (optional). Then add the vegetable stock. Add bay leaves and thyme twigs, pimento seeds and crushed juniper berries and season with salt, pepper and paprika powder. Let the vegetables simmer for about 40 minutes.
Set up a second pot and use a medium-fine sieve: Pour boiled vegetables and all the liquid through the sieve into the second pot. Using a spoon, squeeze out the boiled vegetables as much as possible and pass through the sieve. This process takes a little time. Scrape the vegetables in the sieve as small as possible and squeeze as much liquid through the sieve as you probably can. Put the pressed vegetable residues in the sieve into the organic waste. What remains is the delicious sauce!
Now melt in another pot 25 g margarine. Using a whisk, stir 25 g flour into the liquid margarine and gradually add the sauce. Stir vigorously with a whisk until a rich, dark and creamy sauce is obtained. Season the vegan gravy to taste with salt, pepper and a dash of soy sauce.
