Instructions

1. Gently warm the oil through in a heavy-based pan but do not allow it to boil. Bring to a gentle simmer, then add the chilli, lemon grass, garlic and ginger. Continue to simmer very gently for 20–30 minutes, until the flavours are well infused. It's important not to allow it to boil at any stage. Pour into a squeezy bottle, leaving the bits in, as the flavours will continue to infuse. Use as required.
