The spiciest thing I've ever eaten was a phaal curry from an Indian restaurant . It was a dish of curry with a mix of chillies, including several of the hottest varieties from around the world, cooked in a tomato and onion base and served with a side of naan bread. The heat was intense, almost unbearable for a few moments, but the flavour was incredible. The complex mix of spices, the slight sweetness from the tomato and the smokiness from the chilli all blended together perfectly. Truly an unforgettable experience!
