Rakkyo Onions

Tamanegi onions don’t feature too large in Japanese cuisine. Vegetables that were considered strongly yang in nature (see garlic) – that is, male and powerful – were discouraged in Buddhist temples. One notable exception is in rakkyo, Japan’s answer to the pickled onion. It’s actually a scallion, pickled in either flavored vinegar, with akashiso, or a mix of shoyu and mirin.
