Roma tomatoes also referred to as pasta tomatoes, differ a lot from other varieties. Unlike common tomatoes, these are distinguished by a more prolonged shape, higher acidity, sugar, and pectin, and lower moisture compared to regular tomatoes. Normally Romans don't eat them raw, but rather cook them to make pasta. If you feel like soothing your gourmet curiosity, don't be shy to try a bite of a raw tomato. No one who did so has died so don't worry. The harvest season stretches from June through September.
