There’s no better way to spend a Sunday than tasting heirloom tomatoes at the open-air New Amsterdam Market downtown. All 20 varieties were delicious, and I was more than okay with lining up to try each one. My favorites were the Black Prince tomato (which tasted rather egg-planty) and the Sun Gold cherry tomato. Blame last week’s article in New York magazine, but I’m sort of on a tomato kick. I picked up a quart of cherry tomatoes at the market — guess what I’m eating for lunch?
