Peel and roughly chop the onions and the garlic.

Juice and zest the lemon.

Add all the ingredients except the olive oil to a food processor and blitz into a paste.

Add the olive oil, bit by bit until you have achieved the right consistency and season well with salt and black pepper.

Smear half of the paste onto the meat or fish and leave to marinate for a few hours before cooking.

Baste the meat with the rest of the sauce during the cooking process or save some to use as a dip when the meat is cooked.
