Add the garlic and salt to a food processor.
Pulse on high-speed several times until the garlic becomes finely minced. You may need to stop and scrape down the sides with a rubber spatula.
Stop the food processor and add water and lemon juice.
Process at high speed until it becomes a smooth liquid.
While processing at high speed, slowly add in the oil until it becomes emulsified and resembles the consistency of mayonnaise.
Chill or serve.
