Sending Canned Christmas to High Altitude?

cannond
10 years ago

I need help again. Each year I give my children special canned treats (Preserves, salsas, pickles, etc.) for Christmas.

My youngest daughter has moved to Colorado Springs. When I've visited there I've noticed jars of marshmallow fluff oozing from jars at the market. I expect they were processed at lower altitudes.

Will my canned jams and goodies react to the higher altitudes? Will the contents swell? Will they come unsealed? Help, please.
