Purslane
Purslane was loved by English medieval cooks and gardeners; the ancient Greeks would make a bread flour from purslane seeds. They would pickle the fleshy stems. Today, Greek country cooks serve purslane as a salad herb, either alone or with other wild greens. Mexicans enjoy purslane for its hot, peppery bite when cooked. They enjoy it with eggs (mainly omelets) and pork. Chinese cooks value purslane for its sharp flavor and slightly slippery presence with noodles.
Purslane (Portulaca oleraceae), is a potherb, an annual succulent, a green, and to many, a weed. But it's been found to be a source of Vitamin A, C and E, plus contains an omega-3 fatty acid. And great for calorie counters, as it contains only about 15 calories per serving!
While you can eat the wild purslane you may find in garden of flower beds, you should be careful that it has not been exposed to chemicals. The cultivated varieties are larger and more tender. To grow purslane yourself, you'll need a sunny location with good drainage. If you live in an area frequented by drought, or that is naturally very dry, you'll be pleased to learn that purlsane is drought tolerant.
