No. But you have to be scrupulous about cleanliness and getting the temperatures and proportions of preservatives like salt and sugar right. And eating preserved foods or it’s not worth the bother.
You can make just a few pots of jam etc. in the microwave and this is fun and easy. Google up microwave preserving and enjoy the process and results!
Fruits and anything rich in sugar, and anything fairly acidic like tomatoes is easy. I recommend starting with apples - and new season apples are not far away time wise. Or kimchi - that’s a good starting point too.
Other vegetables like beans or zucchini preserving has some traps for the unwary so probably don’t start with these. Meats are for pros only. Cos botulism and other problems.
