Why you should preserve your tomatoes

Members of the nightshade family, tomatoes were once considered poisonous. But once the myth was dispelled, lovers the world over developed a lust for this plump fruit.

Unfortunately, tomatoes are among the fruits that must be enjoyed in season. Heirloom tomatoes ship poorly. Those fruits found in winter and spring have been bred not to bruise and usually offer flesh the consistency of cardboard.

That’s why Hollywood caterer Anne Janzen created this simple heirloom tomato jam for us. Its flavors are a balance of sweet and savory with just a hint of spice.

Once you try this tomato jam, you will never want to plan a romantic picnic or date night sandwich without this sexy jam.

What is tomato jam?

You may be a lover of jam on your peanut butter sandwiches. But a jam made with tomatoes is not exactly what you picture atop bread slicked with Jif. And you’re right, we wouldn’t serve it that way either!

Jam is a style of preserving made from fruit that is crushed or chopped then cooked with sugar until the fruit begins to fall apart, or at least lose its shape. (And since tomato is technically a fruit, it’s a great candidate for this style of transformation.)

Sugar is the primary preservative in jam. In other words, it’s the ingredient that makes it possible to keep your jar of summer fruits to enjoy all winter long. (Check out this article from Serious Eats if you’re interested in learning more about the differences between jam, jelly and preserves.)

In this particular version of a tomato jam, heirloom tomatoes are combine with the natural sweetness of peaches, (more sugar), and the heat of aphrodisiac chile to form a full-flavored condiment you can reach for all year.
