1. Pound the garlic with a mortar, then use a whisk to combine with salt and 1 egg yolk. Whisking continuously, work in the oil a drop at a time; when it starts to thicken, you can add more oil in a thin stream. When you have a thick emulsion, taste the aioli, season with pepper, then taste again. You can thin it by adding a few drops of water, if desired, or add a little more oil if the garlic is overpowering (though mine was very garlicky and I loved it with the soup). If you have trouble, see this helpful post from
David Lebovitz.)
