Don't fridge yacon tuber. Only the rhizomes, if you need to fridge any of it. Cool cupboard or hung in a cotton bag in the garage in a dark spot works well. These will last many months. Most yacon people watch for when the outside starts to grow some surface mould and then consume the last ones quickly. The mould just cuts off, hasn't entered the tuber. Yacon will look AWFUL and squishy and gross in a matter of weeks and that's when they are best consumed. So age them for a few weeks at least. I'd say 5 months is a minimum to be able to store them and last year I got mine to 8 months before I saw any issues. I'm in a cool and dry climate. The only overdose you'll achieve on yacon is a lot of insoluble fibre that many westerners are not used to and your belly bugs will love and you and others around you may not appreciate. It has no ill effect though and is healthy. If you eat predominantly a vegan or veggo diet than it may not have this effect for you.
