The one appliance I will insist on when we have the room is an extra freezer.
My parents had an old upright freezer in the garage, and that thing was ALWAYS full of meat.
This stupid side-by-side we have now has enough room in the freezer for one half-gallon of ice cream, 10 of those zero-calorie Italian ices in the tube, and two bags of unidentified vegetables Xena's Guy brought home from some family dinner. Nothing else may enter.
My freezer is actually bigger than my refridgerator/freezer....it's a 25cubic foot upright and the one in the kitchen is only 19cf.
Right now it desperately needs to be defrosted........
I cannot believe how much money I save on meat by having an upright freezer in the laundry room. I would make room for one in just about any room in the house, if I had to.
And now I am going to start baking more snack type foods to save on the expensive granola bar scene. Unless I want to be baking 24/7, I have to make a lot at once and freeze it.
Finally, in extolling the joys of a stand-alone freezer: we take an afternoon and everyone makes a pan of lasagne. After chilling it overnight, I cut it into portions and freeze individually. Wonderfully delicious and so convenient to be able to pull out how ever many servings are needed. All kinds of casseroles and home-made prepared foods---soups, curries, meatloaf, meatballs, the list goes on-- can be made at a fraction of the storebought cost and frozen at home.
