Peel garlic clove and smash with the side of a chef's knife. Using a fork, mash the garlic with salt in a small bowl to form a coarse paste. Whisk in oil. Add juice, vinegar and mustard; whisk until well blended. Taste and whisk in up to 4 tablespoons more juice to mellow the flavor; season with more salt, if desired.Advertisement
Make Ahead Tip: Cover and refrigerate for up to 5 days. The oil will solidify, so bring to room temperature and whisk before using.
