Heirloom vegetables are old world cultivars that have been grown and maintained for generations. This curation and preservation of historic varieties lead to vegetables that are more flavorful, varied, and rustic in appearance than their commercially cultivated counterparts. Heirloom tomatoes, depending on the variety, have a wide range of tastes with some being candy sweet and others being refreshingly acidic. However, they are all consistently rich in umami and flavorful.
