I have a 7 or 8 year old foodsaver, no chamber sealer (yet?). My fridge has a quick-chill drawer with fan that will be perfect to cool things down.
Let us know if you notice a difference with the vacuumed base. My wootcreami arrived yesterday, 11 days earlier than expected, and sadly I don't have time until the actual expected delivery day to play with it. Meantime I should probably order some exotic ingredients like gums and add ins I suppose - take the easy route and go with the modernist pantry mixes, or pick up individual types mentioned in MC and member Paul Raphael's web log?
