Salt cod tortilla
About this recipe
Spanish cooking flows from olive oil, garlic, paprika, and tomato — the matriz of the Mediterranean kitchen — applied across tapas, slow-cooked stews, and the seafood traditions of both coasts. Sherry vinegar and Spanish saffron supply most of the brightness and depth.
As a seafood dish, Salt cod tortilla demands timing precision: the difference between perfect and overcooked is often less than 90 seconds, and the result of overshooting is a textural penalty there's no fixing.

Method
- step 1
- Heat half the oil in a frying pan, and sauté the onion over a medium heat until soft and pale gold – this will take about 8 mins. Remove from the pan, set aside, and add the potatoes to the pan. Cook until they are tender but not falling apart, carefully turning every so often. Cover the pan some of the time to help the slices cook through. Add the onions back to the pan along with the garlic and cook for another 4 mins. Tip into a bowl with the eggs, parsley and some seasoning and mix together. Leave to sit for half an hour.
- step 2
- Meanwhile, put the cod in a saucepan and cover with water. Bring up to a simmer. Remove from the heat, cover and leave for 10 mins. Drain, leave to cool and remove the skin and any bones. Break into large flakes and add to the potato and egg mixture.
- step 3
- Heat the rest of the oil in a non-stick frying pan. Pour in the tortilla mix and cook over a medium-low heat until it is just set and coming away from the sides of the pan. You might need to cover it to help the centre set. Be careful not to overcook it. Put a spatula underneath the tortilla every so often to make sure it isn’t sticking. Slide the tortilla onto a plate, then put the pan on top and flip the tortilla into it, uncooked side-down. Cook over a low heat until golden, or grill until just set. Leave to cool a little before serving.
Cooking notes
Scaling works best when you weigh ingredients rather than measure by volume — small differences in packing can compound at higher multipliers.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Salt cod tortilla
Salt cod tortilla is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Seafood is the most scaling-sensitive protein because the overcooking window is narrow and the penalty is steep. Scale Salt cod tortilla per piece if you can — cook three fillets in two batches rather than crowd the pan into one. Sauce-based seafood dishes scale linearly, but always taste before adding more salt: brininess from the seafood itself doesn't scale predictably.
This recipe calls for eggs, which are the trickiest ingredient to scale to non-integer multiples. A US "large" egg weighs about 50 g; if a fractional scaling lands on, say, 1.5 eggs, beat one egg and weigh 25 g of the beaten mixture rather than guessing. The same goes for halving recipes — half an egg is 25 g of beaten egg, not a dramatic estimate.

Beyond the recipe
Substitutions & make-ahead — Salt cod tortilla
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Salt cod tortilla is doing structurally — here's the practical version.
Substitution ideas
Eggs
For binding (cookies, quick breads, meatballs): 1 large egg ≈ 1 tbsp ground flaxseed + 3 tbsp water, rested 5 minutes until gelled — structurally closest to a real egg. For moisture without structure (cakes, brownies): ¼ cup unsweetened applesauce or mashed banana per egg, accepting some loss of rise.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Seafood is the worst-tempered category for make-ahead — texture and flavour both degrade quickly after cooking. Salt cod tortilla should ideally be cooked the day it's served. If a make-ahead is unavoidable, prep components (the sauce, marinade, vegetables, garnishes) the day before and cook the fish or shellfish at the last moment. Cooked seafood develops a pronounced fishy off-flavour within 24 hours even when properly refrigerated.
