Zucchini Flowers Stuffed with Fontina Cheese, Potato Starch makes Delicate Tempura & Light

Only in the last 20 years have I seen these available retail, and even so you’re lucky if you see them once a year and they must be cooked the day they’re harvested. If you have a zucchini plant in your garden, you have to make these. Mangia!
