Rub for Fish

You know when you want to give a simple fish fillet an extra boost, transforming it into a memorable dish? That's where fish rub comes into play. The English word "rub" literally means "to rub", but it is nothing more than a mix of spices and aromas that is applied directly to the surface of the fish before cooking , creating a sort of delicious "crust".

Cooking fish with a rub is a bit like painting on a blank canvas : the fish, delicate in itself, becomes the perfect medium to let your culinary imagination shine. The spices blend with the fish, giving life to more intense and enveloping flavors.

Which fish are best suited for rub?

Salmon

The natural fattiness of salmon allows you to play with even intense spices like smoked paprika , cayenne pepper, chili pepper , or softer aromas like dill, fennel and lemon. A touch of brown sugar or honey powder in the mix can create a fantastic external crust. Direct contact with the embers gives an even more accentuated smoky flavor .

Tuna

Tuna has an intense flavor that is second to none and lends itself very well to bold pairings . Tuna rubs can contain black pepper and chili pepper, but also citrus flavors like orange peel . Tuna is already a tasty fish, so balance is everything. The secret lies in quick cooking at a high temperature : seal the external surfaces in a few moments, leaving the inside still slightly pink if you want to preserve its tender consistency .

Swordfish

Among the “ meatier ” fish, swordfish has a firm texture and a pronounced flavor, which makes it an excellent candidate for rubs. You can dare with Mediterranean notes, such as oregano , thyme and chili pepper, or go for a more exotic mix (for example, with cumin and paprika). A light use of olive oil before applying the rub can help it adhere better to the flesh. Unlike other fish, swordfish holds up well to a brief marinade of 15-20 minutes: in this way, the rub penetrates slightly more.

How to cook fish

If the fish meat is particularly delicate, like cod, or if you want to help the mixture stick, you can brush it with a light layer of extra virgin olive oil before applying the rub. This way, the spices will “stick” to the surface better and the crust that will form during cooking will be even more inviting.

If you are short on time, simply leave the fish to marinate while the grill or oven heats up . Even a few minutes will allow the spices to begin to penetrate the surface layers. For meaty fish such as salmon, tuna or swordfish, you can extend the marinade to an hour, especially if you want a more intense flavor.

After having given due attention to the preparation, it is time to put the fish on the stove (or in the oven) and enjoy the magic of the aromas that are released. If you prefer to cook the fish in the oven , know that this method offers extremely uniform cooking and is ideal for thick fillets or whole steaks of salmon and swordfish.

If you love the smoky flavor, the grill or barbecue are the right choice. However, you must pay close attention to heat management : if it is too strong or prolonged beyond what is necessary, you risk burning the surface. It is advisable to preheat the grill and grease it with a little oil, then place the fillets for a few minutes on each side , adjusting the flame depending on the thickness of the fish.
