Diablo is a cooking term which means “to make it really hot”, similar to devilled where a dish is infused with hot ingredients such as chillies, pepper and mustard. This is most probably of Mexican origin but not 100% sure, I just assumed as I saw this dish on Mexican restaurants, also the ingredients on this dish like shrimps and chillies are popular in Mexico.
The most common recipe for this type of dish is Shrimp Diablo where it can be skewered, placed on pasta or paired with rice. For this recipe I will add Salmon as its mild and creamy flavours would be a great contrast to this great dish. Also I had added some capsicums to have a different texture to the dish. This is for people who loves hot and spicy dishes and not for the fainthearted, but if you want to serve it to those who does not like spicy dishes you can reduce the amount cayenne pepper and add more of the tomatoes.
Serve this dish with rice and finish it with something creamy and cold like an ice cream, yoghurt or sorbet.
