Purslane is available in New York City right now. Tender, but tough, it is actually a succulent. It really stands up to, and compliments, all types of acid. Toss gently with lemon juice, a little rice wine vinegar, a drizzle of olive oil, diced and seeded tomatoes, salt and plenty of pepper. Enjoy a lemony, robust salad high in omega-3 fatty acids–a great source for those who don’t eat fish.
