Make this recipe a recipe that people in that category can eat. categories: ['vegetarian'], recipe: (if you use a food processor, you will no doubt have the perfect mayonnaise--a mixing bowl takes more effort.) place all ingredients, except the oil, in the food processor. start the motor. slowly, drip by drip, add the oil. once an emulsion starts (it starts to thicken), you can add the oil more generously. adjust seasonings--more salt, pepper, lemon. this will last 5-7 days in the refrigerator.

Target recipe: begin with all ingredients at room temperature, they will emulsify more readily. in a food processor or blender, process the yolks, salt, mustard, cayenne, lemon juice and water together to form a base. with the motor running, add the oil in a thin, steady stream. the mixture will take on a whitish color just like mayonnaise (of all things). (after 2 or 3 days covered in the refrigerator make sure it passes the sniff test before using again.).
