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: let all ingredients warm up to room temperature. place egg, lemon juice, dry mustard, salt, and 1/4 cup light olive oil in the food processor. mix for 20 to 30 seconds. while the machine is running drizzle remaining 1 cup of oil very very very slowly into the mixture until emulsified or looks like mayo. taste and add salt if needed.
