Twenty minutes, one pan, and considerably better than the sum of two tins.
The frankfurters are already cooked, so the only decision worth making is whether to brown them. Brown them. Straight from the tin they are pallid and slippery; three minutes in hot fat and they blister, split slightly and taste of something.
- Drain the frankfurters and dry them. Cut into thick diagonal pieces, more cut surface to catch.
- Hot pan, oil, frankfurters in one layer. Three minutes without moving them, then turn. Lift out.
- Dried onion into the same fat for two or three minutes, then garlic and paprika for twenty seconds. Tomato purée in and fried for a full minute, frying the purée rather than stirring it in is the difference between it tasting raw and tasting cooked.
- Beans in with about half their liquid, plus a splash of water. Simmer ten minutes, crushing a few against the pan to thicken it.
- Frankfurters back in to warm through. Vinegar off the heat.
Serves 3. Good with flatbread, and better the moment it comes off the heat than after standing.
