- 500 g white fish fillets
- 2 cups bomba rice
- 1 onion
- 1 tsp smoked paprika
- 1 litre stock
- 1 tsp saffron
- 1 red pepper
- 1 tbsp olive oil
- Salt and black pepper, to taste
Method
Step 1. Rinse the rice or grains until the water runs clear, then drain.
- Heat
- Off, no heat yet
- Look for
- Pieces are roughly the same size, so they all finish cooking together.
- Why it matters
- Even pieces cook at the same speed. Prepping everything first (mise en place) stops you scrambling once the pan is hot.
- Avoid
- Cutting pieces of mixed sizes: small ones burn while big ones stay raw.
Step 2. Cook the onion in a wide pot with oil until soft and fragrant.
- Heat
- Medium to high, stir or flip now and then
- Look for
- Golden-brown edges, a steady sizzle and a toasty smell.
- Why it matters
- Browning (the Maillard reaction) creates deep savoury flavour that boiling cannot.
- Avoid
- Overcrowding the pan: the temperature drops and food steams. Cook in batches.
Step 3. Add the fish and cook until lightly browned, about 5 minutes.
- Heat
- Keep the heat steady
- Look for
- The new ingredient is coated and the mixture returns to a gentle bubble.
- Why it matters
- Adding things in order lets each ingredient cook for just the right time.
- Avoid
- Dumping everything in at once: delicate items turn mushy before tougher ones are done.
Step 4. Stir in the rice with smoked paprika, stock and saffron and double the volume of hot water or stock.
- Heat
- Keep the heat steady
- Look for
- The new ingredient is coated and the mixture returns to a gentle bubble.
- Why it matters
- Adding things in order lets each ingredient cook for just the right time.
- Avoid
- Dumping everything in at once: delicate items turn mushy before tougher ones are done.
Step 5. Cover tightly and cook on low heat for 16 minutes without lifting the lid.
- Heat
- Low, with small lazy bubbles
- Look for
- Small bubbles break the surface gently; the sauce thickens and the food turns tender.
- Why it matters
- Gentle, steady heat softens tough fibres and lets flavours blend without drying things out.
- Avoid
- Letting it boil hard, which toughens meat and reduces the liquid too fast. Lifting the lid too often loses heat.
Step 6. Rest for 10 minutes, fluff with a fork and garnish with red pepper.
- Heat
- Off, let it sit
- Look for
- Steam slows, juices settle and the dish firms up slightly.
- Why it matters
- Resting lets juices redistribute and flavours settle, and the food is easier to slice and eat.
- Avoid
- Skipping the rest: juices run out and the dish falls apart.
