This is one of those recipes where the browning sauce does all the heavy lifting. If you've never used it, browning sauce is basically liquid caramel — it gives the chicken that deep mahogany color and a slightly sweet, smoky backbone without any complicated technique. I brown the chicken first to build a fond on the bottom of the pot, then everything braises together. The ketchup isn't weird — it's traditional. It adds acidity and a touch of sweetness that balances the allspice and thyme. Make a big pot because this tastes even better the next day once those flavors marry overnight in the fridge. Serve it over rice and peas and you've got a complete meal with almost zero effort on day two.
