If you’ve already made the mayonnaise, combine it with all the remaining ingredients. If you’re making the mayonnaise for this recipe and you’re using a food processor or blender, you can save yourself some mincing by adding the garlic at the beginning and pulsing in the other solid ingredients while the sauce is still in the machine.
The sauce will keep well in the refrigerator for a few days, though it will lose a bit of intensity each day. To freshen it before serving, squeeze in a little lemon juice.
