If you have never eaten an heirloom tomato, you are missing out on a delectable food. They are more pricey, but drastically better than regular tomatoes. You don’t have to get them all the time, and because of the price I wouldn’t make a sauce with them, but if you like to eat tomatoes raw or drizzled in some olive oil with a few spice, heirloom is the way to go.
They can be an assortment of colors–red, orange, green, yellow. It’s like eating a summertime rainbow. I know that sounds corny, but they are that good, especially if you can get them fresh out of a garden.
If you have a garden, consider growing an heirloom variety tomato.
