Guyanese Chicken Curry with Roti

I want to understand how Indian cooking changed when it crossed an ocean, and Guyanese curry is one of the clearest examples: the spice blend is milder, fresh herbs and a hot pepper replace most of the whole-spice work, and it is one pot in under an hour. The technique I expect to learn is frying the curry paste first, the opposite of how I usually make curry and the step Guyanese cooks insist is the entire difference. The roti is the second lesson; a flatbread that puffs on a dry griddle in a minute is a skill I would use weekly. It is weeknight-feasible because the roti cooks while the curry simmers. The pepper goes in whole and comes out before serving, so my son's portion is mild.

• Caribbean curry powder: Chief, Lalah's or Betapac, from Caribbean groceries or online. Madras-style curry powder is the closest supermarket substitute; add 1/2 teaspoon cumin and a pinch of ground fennel to lean it Guyanese.
• Green seasoning: A fresh paste of scallion, garlic, thyme, cilantro (or culantro) and onion, the universal Guyanese marinade; make extra, it keeps a week.
• Wiri wiri pepper: A tiny, round, very hot Guyanese chile. A Scotch bonnet or habanero left whole in the pot gives aroma without much heat; remove it before it bursts.
• Garam masala and ground cumin (geera): Added at the end for warmth.

1. Green seasoning: blend 4 scallions, 4 garlic cloves, the leaves from 4 thyme sprigs, a big handful of cilantro, a quarter of the onion and 2 tablespoons water into a coarse paste. Toss the chicken with 3 tablespoons of it and 1 teaspoon salt; set aside (or refrigerate up to a day).
2. Roti dough: whisk 3 cups flour, 2 teaspoons baking powder and 1 teaspoon salt. Add about 1 1/4 cups warm water gradually to make a soft, slightly sticky dough. Knead 3–4 minutes until smooth, rub with oil, cover and rest 20 minutes.
3. Peel the potatoes and cut into 1 1/2-inch chunks. Dice the rest of the onion and the tomatoes. Mince the remaining garlic.
4. Stir the curry powder and cumin with 1/4 cup water into a thick, pourable paste.

1. Heat 2 tablespoons oil in the Dutch oven over medium heat. Cook the onion and garlic 3 minutes. Pour in the curry paste and fry, stirring constantly, 2–3 minutes until it darkens a shade and smells toasted rather than raw; add a splash of water if it sticks.
2. Add the chicken and its marinade. Stir to coat and cook, stirring now and then, 8–10 minutes so the chicken browns in the paste.
3. Add the tomatoes, potatoes, the whole hot pepper and 1 1/2 cups water, enough to come most of the way up the chicken. Bring to a simmer, cover and cook 25 minutes.
4. Uncover and simmer 5–10 minutes more until the potatoes are tender and the gravy coats the chicken. Fish out the pepper. Stir in the garam masala and a squeeze of lime, taste for salt and rest 5 minutes.
5. Roti, while the curry simmers: divide the dough into 6 balls and roll each into a thin 8-inch round. Heat the dry skillet or tawa over medium-high. Cook each roti about 1 minute, until bubbles form, flip and cook 1 minute more, then flip again and press gently around the edges with a folded towel so it puffs. Stack in a towel.

Give everyone a bowl of curry with a piece of chicken and a couple of potatoes under a good ladle of gravy, with roti folded on the side. The Guyanese way is to tear a piece of roti, pinch up chicken and gravy with it and eat with your fingers. With the pepper kept whole and removed, this is a warming curry rather than a hot one, so my son's bowl is the same as ours; the adults can mash the retrieved pepper into their own bowls or add Caribbean pepper sauce. The curry is better the next day and keeps three days; roti reheats in a dry skillet for 30 seconds a side.
