I used to eat at a small pizzeria in the northeast, and I swear they had the best tomatoes. During the early summer months, the pizzeria would run a special veggie pizza. The pizza was loaded with caramelized sweet onions, crimini mushrooms, serrano peppers, and the sweetest heirloom tomatoes. The flavor was incredible, and all of the ingredients were form local farms.
I have since moved out west, and I have to say I miss the good pizza. I still haven't found heirloom tomatoes in my city that compare with the farm fresh heirlooms that were served at this pizzeria. For this reason I have been contemplating learning how to grow heirloom tomato plants.
