Notes
Roasting Garlic – use 2 big cloves. It is sweeter and milder than raw garlic. Spray it with olive oil, wrapped in foil and bake at 400 degrees F for 45 to 55 minutes.
If you don't care for mayo, substitute with Greek yogurt.
This sauce is much tastier after a day, so make it in advance for ingredients to blend well.
Applying a thin layer of this sauce is enough to flavor your food.
Other of your favorite ingredients can be added to aioli, refer to blog. Let me know in the comment if there’s anything you can recommend.
