2024 - What I did today

Perhaps a hotbin is another thing I can talk myself out of then, along with an airfryer

.......and a dehydrator and a vacuum sealer????

..............mention of dehydrator above reminded me of something I did yesterday. I threw out dehydrated beef, pork & chicken which I had in tupperware in the fridge!
It had started to go mouldy!
How can you store dehydrated produce so it doesn't go mouldy. How are they able to sell dehydrated beef jerky in packetss that doesn't go mouldy?

The only way I can think of is to freeze it after drying? which sort of defeats the object?
