In our house, we use this flavourful ‘chilli mash in oil’ for practically everything: to spice up and deepen the flavour of soups, stews, sauces, lentils, beans, sandwiches, marinades and barbecued meats. It has become quite indispensable in our everyday cooking, and we simply can’t be without a jar of ají in the fridge. The bottom of the jar has a thick layer of fairly hot, mashed chillies, covered by a second layer of milder, chilli-infused oil. Both can liven up pretty much anything, and a little ají goes a long way...
