What You Need to Know
The process combines mechanical coating (adhesion of ground peanut powder to protein surfaces) with pyrolysis of chili capsaicinoids and Maillard reactions between amino acids and reducing sugars in the peanut-spice blend. Key reactions include the degradation of piperine (from black pepper) and gingerols at ~140°C.
Creates a dual-textured bite - crackling spice crust giving way to juicy interior. The peanut base (often including roasted peanut oil) carries fat-soluble flavor compounds from spices while protecting meat from direct flame charring. Traditionally served with sliced onions and spicy yaji pepper dip.
