Ingredients (serves 1–2)
- 200g fresh seafood (e.g. prawns, mussels, squid)
- 2 medium potatoes
- 1 onion
- 2 cloves of garlic
- 1 tablespoon yellow chilli paste (ají amarillo)
- 300ml fish stock
- 1 tablespoon olive oil
- Salt and pepper, to taste
- Fresh coriander leaves, to garnish
Shopping for the ingredients
When shopping for cau cau de mariscos, it is important to look for the freshest seafood you can find. Visit a local market or a trusted fishmonger to track down the best, most recently caught produce. The quality of the potatoes and the freshness of the onion and garlic can also make a real difference to the finished flavour. Try to choose a yellow chilli paste without added preservatives, so the authentic taste of the dish stays true.
Preparing the dish
Preparing the dish involves a few important steps before the cooking itself begins. First, peel the potatoes and cut them into small cubes so they cook through evenly. The onion and garlic should be finely chopped to release their aromas fully. It helps to have everything prepared and within easy reach in advance, so the cooking process moves along quickly and smoothly.
Step-by-step instructions
- Heat the olive oil in a pan and add the onion, cooking until it turns translucent.
- Stir in the garlic and the yellow chilli paste, and fry briefly to bring out the aromas.
- Add the diced potatoes and the fish stock, then bring everything to the boil.
- Add the fresh seafood and let it simmer over low heat until the potatoes are soft.
- Season with salt and pepper, then garnish with fresh coriander leaves.
Gluten-free / lactose-free version
Cau cau de mariscos adapts beautifully to a gluten-free and lactose-free diet. The recipe is naturally gluten-free, as no wheat products are used. For the lactose-free version, simply use fish stock and oils free from lactose, so the dish suits anyone with a lactose intolerance. Take care to choose your ingredients thoughtfully to avoid any cross-contamination.
Tips for vegans and vegetarians
For vegans and vegetarians, cau cau de mariscos is easy to adapt by swapping the seafood for vegetables such as courgette, carrots or aubergine. These vegetables adjust the taste and texture of the dish, while the yellow chilli paste and spices keep the aroma vibrant. Tofu or seitan can also add extra sources of protein. Be creative with the ingredients to build a dish that is both unique and full of flavour.
More tips and tricks
A few tips and tricks can help you get the best from cau cau de mariscos. Use fresh herbs to refine the dish, and experiment with different spices for a personal touch. It is also worth briefly blanching the seafood before it goes into the pan, to preserve its freshness and firmness. Above all, take care not to overcook the dish, so the seafood stays tender rather than turning rubbery.
Adapting the recipe to your taste
The recipe for cau cau de mariscos is easy to tailor to your own preferences. You can vary the type of seafood depending on what is available and what you enjoy most. You can also dial the heat up or down by adjusting the amount of yellow chilli paste. If you like things creamier, a splash of cream or coconut milk gives the sauce a richer consistency.
Ingredient substitutions
If some ingredients are hard to find, there are several alternatives you can turn to. Instead of yellow chilli paste, try fresh green or red chillies for a slightly different flavour profile — the same fresh heat that lifts a plate of Aji de Langostinos. If you cannot source fish stock, vegetable stock works well as a stand-in and makes a vegan variation possible. See which options are available in your area, and do not be afraid to experiment with something new.
Drink pairing ideas
For a perfect meal, the right drinks make all the difference. A lightly chilled, well-structured white wine complements the flavours of cau cau de mariscos wonderfully. Alternatively, a fruity, gently sweet Chicha Morada harmonises nicely with the spiced notes of the dish. For those avoiding alcohol, a refreshing lime juice or a homemade lemonade makes a lovely accompaniment.
Serving and presentation ideas
Thoughtful presentation can lift the whole cau cau de mariscos experience. Serve the dish in a deep bowl and garnish it with fresh coriander leaves for an attractive contrast. A few lime wedges add a fresh note and please the eye too. Consider serving the dish with crusty bread or tortillas to round out an inviting and complete meal.
