This Low Calorie Special Sauce has the same delicious tang of In-N-Out's Special Sauce - but lightened up! Enjoy this sauce with burgers, chicken, fries, and whatever else your heart desires, without any guilt!
Add all ingredients to a small food processor or blender and pulse/blend to combine. Taste and add more sugar, salt or seasoning to taste. Add more milk for a thinner consistency.
Refrigerate for at least an hour before serving. Best when refrigerated for 24 hours. Keep stored in an airtight container in the fridge for up to a week.
Notes
To make dairy-free: use dairy-free yogurt or omit and add 1/4 cup more mayo.
