When it comes to zucchini (also call courgette), smaller is better. Choose unblemished zucchinis about 7-9 inches (18-22 cm) long and 2 inches (5cm) in diameter. If you are picking them from your garden, the golden flowers are edible too. Here's a traditional fried zucchini blossom recipe. Zucchinis are available year round, but are at their peak during summer months in North America.
