<human>:  I am looking for a way to make an aioli sauce from scratch.
<bot>: To make aioli sauce from scratch you will need to gather a few ingredients. You will need mayonnaise, garlic, lemon juice, salt, and pepper. Begin by mashing the garlic and adding it to the mayonnaise in a bowl. Slowly add the lemon juice, salt, and pepper to the mixture and stir until fully combined. Taste the mixture and adjust any ingredients as desired. Refrigerate for 1 hour to let the flavors develop before serving.
