Chilli is one of the most commonly used spices in the world. It is used for adding heat to dishes. On a scale of 1 to 10 ground chilli has a heat rating of 7 (seven). Chillies (crushed or ground) are added to curry pastes, fragrant spice pastes, marinades, pickles, chutneys, salsa and sauces. When adding chilli to recipes, add less rather than more (as more can always be added to taste).
