Preserving corn by canning is safe and easy, if you use proper methods! If you are canning corn always use a pressure canner. Dehydrating and pickling are 2 other great options I've linked to below. Also below find a quick video on a super duper easy way to get the kernels off the cob!
This is my son and a couple of friends on a corn picking trip we took. What an adventure!
LOL We had a blast. What great memories.
No you should NOT use a waterbath when preserving corn. The reason is Botulism
Be safe… use a pressure canner.
Sweet corn is easy to can though it is time consuming. Get some help husking and cutting the kernels off the cob and it will go quick!
Blanch your corn, cut it off the cob, lay out on dehydrator trays and dry. Doesn't get any easier. Re-hydrated sweet corn is delicious with a splash of cream.
Pack into freezer bags or freeze the whole cob. Be sure and label and date your bags.
Boil your leftover cobs after you can or dehydrate. Add pectin and sugar and make a delightful jelly. Great as a present.
