Delicious classic Caribbean dish. I always get asked for the recipe.
Why does browning the cubed lamb in small batches matter so much for the final sauce? Culinary science points to the Maillard reaction, a complex series of chemical transformations between amino acids and reducing sugars that happens efficiently only when surface moisture evaporates completely. Crowding a Dutch oven drops the pan temperature below the 300 degrees Fahrenheit threshold required for these savory compounds to form.
Avoid boiling the liquid aggressively, which causes the proteins to seize up prematurely. Proper temperature control transforms tough cuts into tender morsels enveloped in a rich, spiced reduction.
