Note We used Goya pimientos, which are available in jars from select delicatessens. If you don't have a gas stovetop, you can roast the tomatoes in the oven at 220C until their skins blister (10 minutes).
This Spanish-influenced fish dish is from the gulf state of Veracruz. Snapper is the fish of choice, but you could use any firm white-fleshed fish. If you have time, you can replace the preserved pimiento with red capsicum cooked slowly over an open flame until charred (as in step 1), then peeled. This dish goes well with steamed white rice and a squeeze of lime juice.
