Peel and freeze the garlic cloves at least 4 hours beforehand

Once you are ready to make the toum, add the garlic, salt and egg white to a food processor and blitz well

Keep the blender on medium and add ¼ of the oil and blend

Then ever so slowly add alternating amounts of oil and lemon juice in a tiny steady stream

When the mixture has come together, add an ice cube and blend for another 30 seconds or so until the mixture goes fluffy.
