Notes
Tips and tricks
Let the sauce chill in the fridge for at least 30 minutes before serving. This will give all of the flavors time to mingle and get to know each other.
To make vegan In-N-Out sauce, substitute mayonnaise for your favorite plant-based mayonnaise.
This DIY version of In-N-Out’s signature sauce lasts for up to 2 weeks in the fridge. Make sure to keep it in a tightly sealed container to help it stay fresh.
You can also freeze it for 2 to 3 months. Some separation may occur, which is why refrigerating the batch is best.
