What You Need to Know
The sauce relies on Maillard browning during roasting to develop melanoidins and aromatic oils, a controlled reduction to concentrate flavors, and fat–water emulsification to create a smooth, velvety texture. Chocolate introduces cocoa flavanols and theobromine, while toasted nuts contribute fatty acids that stabilize the emulsion.
