Aglione garlic is often harvested in June in Tuscany, so if you live in the area, you can often find it in specialty shops and farmers markets during the summer. If you live outside of Italy, it can be tough to find. You may be able to grow it yourself or order it (though it can be expensive). Cooking regular garlic at a slow temperature yields a milder flavor, similar to aglione. For more details, I recommend ItalyBite's Aglione product details.
