Shatteringly crisp, nutty, salty, a fragrant citrus hit from coriander seed and lime leaves, and the lingering warmth of black pepper. This is everything you could hope for in a snack. Kaki lima vendors will deftly ladle batter straight into a vat of oil, expertly letting it slide down the edges to set, then shuffling it into the bubbling centre for a final crisping. I go for the foolproof method of cooking on the base of a frying pan.
