Tin Boom
Tin Boom & Pantry Suppers
Pop a tin of mackerel exactly fifteen minutes before dinner, letting the fish hit a heavy Dutch pot with a loud hiss as the onions blister. "Tin Boom" was the ultimate Jamaican struggle meal, and the secret is the oil: taking five minutes to sauté fresh thyme, a fiery Scotch bonnet, and alliums until they surrender their essential oils creates a flavor base so potent it transforms ordinary pantry fish into a deeply comforting stew that asks for nothing but a hot bowl of white rice. Put the rice on before you touch the tin.
Ingredients

- yellow onion1 med
- scallions2 med
- garlic cloves3 med
- red bell pepper1/2 med
- green bell pepper1/2 med
- fresh thyme3 sprigs

- canned Jack Mackerel in tomato sauce15 oz
- black pepper1/2 tsp

Method
- 01
Build the aromatic oil base.
Heat the oil in a skillet over medium heat, then add the onion, scallions, garlic, bell peppers, thyme, and Scotch bonnet. Sauté for 3 to 5 minutes until the onions are translucent and the oil is highly fragrant—this is the crucial step that dictates the soul of the dish.

Flash out the tin.
Pour the mackerel and its tomato sauce directly into the skillet. Splash a couple tablespoons of water into the empty can, swirl it around to catch every last drop of the leftover sauce, and pour that into the pan as well.

Gently break down the fish.
Using a wooden spoon, gently split the large blocks of mackerel down the middle. Break them into bite-sized chunks, but do not stir aggressively; you want distinct pieces of fish, not a mashed soup.
- 04
Season and simmer down.
Fold in the black pepper, all-purpose seasoning, allspice, and vinegar. Reduce the heat to medium-low, cover, and let it simmer for 5 minutes until the watery tomato sauce reduces into a rich, slightly thickened gravy.
- 05
Serve immediately.
Discard the thyme sprigs and serve hot, ideally spooned over plain white rice to catch all the deeply seasoned oil.
Notes
Managing the heat.
If you want the signature flavor of the Scotch bonnet without the intense fire, drop the pepper into the oil whole instead of mincing it, and carefully remove it before serving.
Dealing with the bones.
The soft, calcium-rich spine in the center of canned mackerel is entirely edible and traditionally left in the pot, but you can easily slide it out when splitting the fish if you prefer a smoother texture.
