As a trained cellist, food writer and cook Gurdeep Loyal relies on music theory to amplify flavour. While he spends more time in the kitchen than in the string section these days, Gurdeep's first two cookbooks lean heavily on musical ideas, such as the flavour chords and triads that underpin all his recipes. Building on those concepts, his new cookbook, Flavour Heroes, takes fifteen underutilised pantry items and builds a repertoire of meals, snacks and sweets around each one.
