In this video, Chef John breaks out the mortar and pestle to make homemade aioli the traditional way. This method calls for crushed garlic and fresh tarragon, worked in a mortar and pestle, and then mixed into mayonnaise and whipped up with a splash of lemon juice. Simple! This mortar-and-pestle technique is really the only way to get that tell-tale sharp, intense flavor in the aioli. Try variations using whatever fresh herbs you like. Watch the video, then get the recipe for Chef John's Tarragon Aioli. Enjoy this intensely flavorful sauce with vegetables, fried potatoes, Chef John’s Salmon Cakes, and baked or grilled fish and meats. The best thing about it? It’s so flavorful, a little dab’ll do ya!
