Roast the Chicken the First Time
50 Mins • Roasting
180°C (350°F)
Heat the oven to 180°C (350°F). Set the seasoned chicken on a rack in a roasting tin, breast-side up, and roast for 50 minutes, until the skin is deep golden and crisp. Check the thickest part of the thigh with a thermometer — it must read at least 74°C (165°F) — and let the juices run clear when pierced. Rest the chicken on a board for 10 minutes so the juices settle before you cut it.
If the skin is browning too fast, tent it loosely with foil for the last 15 minutes; never turn the oven down, or the skin goes soft.
Done when: Skin is crisp and deep golden; thigh reads 74°C (165°F) or higher and the juices run clear.

Char the Onion and Toss the Chicken
10 Mins • Hands-On
Hot dry pan, about 200°C (390°F)
While the chicken rests, heat a dry frying pan over high heat and char half the sliced onion for 2 minutes, tossing once, until the edges blacken in spots — this smoky note is part of the dish. Cut the rested chicken off the bone into bite-size pieces, keeping the crisp skin with the meat. Tip the warm chicken, the charred onion, the raw onion, green pepper, cucumber, spring onions and the whole scotch bonnet into the mayonnaise bowl and toss gently until every piece is coated.
Toss while the chicken is still warm — the heat softens the vegetables slightly and helps the mayonnaise cling.
Done when: Every piece of chicken is evenly coated in the pale, creamy mayonnaise and the vegetables are just starting to soften.

Roast a Second Time in Parchment
25 Mins • Roasting
180°C (350°F)
Spoon the coated chicken onto a large sheet of baking parchment, fold it into a loose parcel and twist the ends closed. Set the parcel on a baking tray and roast at 180°C (350°F) for 25 minutes. The parcel steams gently inside, the mayonnaise warms through and turns into a tangy coating, and the vegetables soften without losing their bite. Open the parcel carefully — the steam is hot — and check the chicken is piping hot all the way through, at least 74°C (165°F).
Do not wrap the parcel tightly: leave room for steam, or the mayonnaise squeezes out and the chicken stews instead of roasting.
Done when: The parcel is puffed with steam, the chicken is piping hot at 74°C (165°F), and the mayonnaise is warm and glossy, not split.

Rest and Serve
5 Mins • Resting
Off the heat, cooling from 180°C (350°F)
Rest the opened parcel for 5 minutes, then fish out the whole scotch bonnet, taste, and adjust the salt and lime. Scatter the reserved spring onions over the top and serve hot, straight from the parchment, with chikwangue or fried plantains on the side for scooping up the creamy coating.
Serve it hot and eat it while the coating is still warm — once it cools, the mayonnaise firms up and loses its shine.
Done when: The chicken is hot, glossy and creamy, with bright green spring onions on top and the vegetables still crisp.

Serve the poulet mayo hot from its parchment parcel with chikwangue (kwanga) or fried plantains, as in the photo, and let everyone scoop the creamy chicken with the bread. The mayonnaise coating is the dish — do not serve it cold or the magic is gone.
