at the beginning i thought the same! it is not so useful and it is expensive..!
but recently I went to a culinary meeting in which a few professional explained the importance of eating the right food (fresh food) and the good eating habits and the food preservation!
They show us the blast chiller and his functions (thousand function! I was surprised)
When I came home I wasn’t sure, probably too many information ;) i thought it was a way to make me spend money! so I get informed …. Lot of people recommend it!
It is useful in keeping food fresh longer without bacterical ploriferation and deterioration, the taste of the food is much better and so on! Ah I was forgetting…more time for ourselves because the cooked food last 5/7days, and less money to spend in food!
If this is the reality I have to buy it!! ;)
