Lightly crush garlic cloves to release more flavor.
Make sure the white pith is removed from the lemon peel, as it tends to impart a bitter flavor. Twist the lemon peel to release more flavor.
Bring oil to 200 degrees Fahrenheit, add the spices, and remove from heat. Let the oil cool to room temperature, stirring ingredients every few minutes. (Oil should sit for 20-30 minutes.)
Once cooled, strain spices and transfer to a glass bottle. Oil will keep for up to a month in a cool, dry place.
