I picked up one of these vacuum-seal devices last summer and love it. It's really changed the way we eat onboard. While I love cooking
aboard, sometimes we just want to eat and play. Since we hop between our land-bound home and our floating home it really works well for us.
If, for instance, I'm cooking
up a spaghetti sauce, or cooking a ham, I'll make an extra large portion, thenseal and freeze the rest. Same with hamburgers or steaks, I'll buy a larger portion, then freeze them raw. After a while I build up quite a lauder, and when we head
down to the boat I can easily have a weeks worth of meals
prepared (we tend to stay out for a week at a time).
To prepare them, just pop them unopened into a boiling pot of water
(for pre-cooked items) for ten or fifteen minutes, cut the bag open and pour it out. No mess, no cleanup, and the benefit of a healthy home-cooked meal. I've never had a problem with freezer-burn.
We also use it on non-food items we want to keep dry. The machines are a bit expensive (ours was around $100 US) but it's easily paid for itself in just waste reduction alone (and probably many times over in meals
we ate aboard instead of just eating ashore to avoid the hassle of cooking).
