As summer winds down, farmers markets overflow with peaches, tomatoes, berries, cucumbers and other seasonal favorites. While those flavors may be fleeting, preserving fresh produce allows you to enjoy the harvest well beyond the growing season.

From jams and pickles to fruit preserves and relishes, home canning is one of the oldest — and most rewarding — ways to reduce food waste and capture peak-season flavor. Whether you're preserving a garden harvest or stocking your pantry with farmers market finds, understanding the basics of safe food preservation is the first step.

The History of Home Canning

Long before refrigeration, people preserved food through drying, curing, fermentation, pickling and salting.

Modern canning began in the early 1800s when French confectioner Nicolas Appert developed a method for preserving food by sealing it in glass containers and heating them to prevent spoilage. His work, inspired by Napoleon's search for reliable food preservation for the French military, laid the foundation for modern home canning.

Scientists later discovered why the process works, thanks to Louis Pasteur's research on microorganisms. In the late 1850s, John Landis Mason introduced the threaded glass Mason jar with a reusable lid system, making home canning more practical than ever.

Today, home canners rely on tested recipes and modern equipment to safely preserve everything from fruit jams to pickled vegetables.

Preserve Peak-Season Produce

One visit to Brooklyn's Grand Army Plaza Greenmarket inspired Chef Jenny McCoy to stock up on late-summer produce from Phillips Farms. Her haul included:

Blackberries
Blueberries
White nectarines
Pluots
Jersey peaches
Kirby cucumbers
Serrano chiles
Jalapeños
Tomatoes

After sharing the bounty with a neighbor, an afternoon of canning produced a pantry full of sweet and savory preserves, including:

Blueberry-thyme jam
Blackberry jelly
Peach preserves with lemon and vanilla bean
Nectarine-coriander mostarda
Tomato-peach salsa
Garlic dill pickles
Bread and butter pickles
Pickled peppers

The result? A delicious reminder of summer that can be enjoyed for months to come.
