I love to make my own infused oils as they are so much fun to use in my cooking.
Garlic oil, of course, is one of the most prepared flavored oil as you can enjoy it with almost all food. It gives it that deep flavor, while not being too overpowering.
I do not recommend chopped garlic as it will be too strong of a flavor and will turn rancid if not used within a month. I will never make that mistake again.
Once you will taste this, you rarely will purchase yours at the grocery store. The flavors are not the same.
