December in Chestnut Hill is when the cold settles deep into our cozy valley and the neighborhood turns inward — white lights on Germantown Avenue, magnolia wreaths on stone houses, and kitchens humming with slow, comforting projects. It’s also an ideal moment for a little Canning 101, winter-style: calm, small batches with none of the summer chaos. Unlike July’s tomato marathon, December canning is peaceful, almost meditative. A pot can simmer while you watch for flurries over Mermaid Lane, and jars can sterilize while the house fills with citrus steam.

Even in the region’s earliest days, winter preservation was a cherished ritual. Records note Martha Washington insisting on “winter stores” of pickled cabbage, citrus, and spiced berries, and local lore says Gulielma Penn — William Penn’s first wife — preferred the cold months for her “kept fruits,” trusting the chill to slow spoilage before anything met the fire. Their instincts still echo in Northwest Philly kitchens today. As a local green thumb, Daniel Preston, says, “By the time winter rolls around, I am thrilled for anything that reminds me of my garden.”

What to can in December

These are perfect for cozy afternoons at home — or for the nights when McNally’s is too packed and Tavern on the Hill feels a bit too far a walk.

Beginner: Pickled Red Onions are fast, foolproof, vibrant. Ideal for holiday boards and sandwiches.

Adventurous: Citrus Marmalade made from Fresh Market’s December oranges make bright, fragrant jars; requires a little patience and a candy thermometer.

Expert: Mincemeat Base — A rich, boozy nod to historic Philadelphia holiday tables; long simmering and precise ratios reward the experienced canner.

Mid–December may leave the branches bare along Germantown Avenue, but inside the neighborhood’s stone houses, it’s the perfect time to fill a few jars, warm the rooms with spice, and continue the quiet winter traditions — old and new — that make the season feel abundant. By summertime, you may even be ready to try your hand at tomatoes.
