Put all the ingredients together in a pan and warm over a low heat, so that the butter melts and the garlic cooks gently. The sauce will need to simmer for around 3-5 mins, until it is fully heated through and the garlic is tender and fragrant. Taste and adjust the seasoning if needed. Serve warm as a dip or drizzle over chicken wings. Any leftover sauce will keep for up to five days in the fridge.
