We just recently purchased this gadget called a Food Saver; it is very similar to the Seal-A-Meal. Well so far we love it, after reading KYH's recipe for the Avacado/Fish recipe I bought a perfectly ripe & ready avacado Sat. to use for the recipe, knowing I'd not get around to using the avacado right away I stuck it in the Food Saver plastic bag and sealed it. Today the avacado still looks as fresh as the day I sealed it, and I did not apply any lemon or vinegar to the avacado flesh to help preserve it. The avacado sealed and has not turned the least bit black or brown as avacado's exsposed to air normally do. I am very pleased with this gadget, and we are adding (slowly) accessories for it. I plan on using it for freezing all our excess veggies from the garden, meats that we freeze (large pkg's that we have to break down) and leftovers that we want to freeze for later on, as well as any sun-dried tomatoes that I may manage to dry properly (in my car
). Just thought I would pass the word on...
