— Why not just cornstarch

Cornstarch clouds, breaks, and weeps in the freezer. These don't.

Modified starches are engineered to do what plain cornstarch can't: hold a glossy, clear set, stand up to acidic fruit, and survive freezing and reheating without turning to water. If you've ever had a pie filling weep or a freezer jam go grainy, this is the fix.

These are pantry workhorses for anyone who cans fruit pie filling, bakes in volume, or makes freezer jams and sauces. A 50-pound bag lasts a small bakery a long while — and they keep indefinitely if stored dry.

— Finish the job

A clear, glossy filling deserves a proper pan under it.

If you're thickening pie filling by the batch, you'll want pans that bake evenly and a domed lid to carry the result. Our Nordic Ware bakeware is the natural companion to a canning afternoon.
