Sauce first, because polenta waits badly and sauce waits well.
- Chorizo sliced thin, cold pan, five minutes until curled and the fat has run. Lift out.
- Dried onion into the fat three minutes, paprika twenty seconds.
- Tomatoes in, cooked down hard 12 minutes to brick colour. Chorizo back in, vinegar off the heat. Tip into a bowl and rinse the pan.
- 600 ml well-salted water to the boil. Rain the polenta in with one hand while stirring hard with the other.
- Five minutes stirring until it ribbons off the spoon.
- Polenta into bowls, sauce over.
Serves 3.
