Having chilli oil in your kitchen cupboard is a must if you’re a fan of chilli heat. Made simply from oil infused with dried chilli peppers, this smooth, flavoured oil delivers a piquant punch. A key ingredient in Sichuanese cuisine, it features in a number of classic dishes such as hot-and-numbing chicken slices or dan dan noodles. A versatile condiment, it can be added to stir-fries, used in salad dressings or served as a dipping sauce to accompany dumplings and noodle dishes.
