Remove the bones and tendons from the venison and dice. Peel the garlic and onions and cut into slices. Mix the meat, garlic, onions, herbs, cognac and oil, cover and refrigerate for 24 hours.
Then drain the meat mixture and collect the marinade. Dice the bacon, fry in a saucepan, remove. Fry the meat mixture with the tomato paste in portions in the bacon fat.

Open the pot, remove the herbs, continue cooking for 30 minutes. Season to taste with salt and pepper.
