Heat the oil and fry the chorizo in it until crispy and remove it. Fry the meat in portions and remove.
Sauté the onions and garlic in the frying fat, stir in the thyme and tomato paste and fry briefly. Add the meat again and season with salt, pepper and paprika. Add the wine and let it boil down briefly. Roughly chop the tomatoes and add to the goulash with their juice and broth and let simmer covered for approx. 60 minutes over low heat.
Fold the paprika and the seared chorizo into the goulash and heat briefly. Season to taste with salt, pepper and sherry vinegar.
If the sauce is too thin, thicken with mixed cornstarch.
