You might not need a refrigerator!
I just tested, out of curiosity, how cold my lowest and smallest stovetop burner goes. I turned it down to zero, and it was cold to the touch. A great refrigerating temperature!
For reference, it's recommended to defrost poultry in the fridge, but I put some frozen chicken on the stove and it defrosted just fine, maybe even a little faster.
I've since added butter, fruit, vegetables, and everything looks perfectly okay so far. Just what I wanted! This will be really handy when cooking for just the two of us, and we have 5 days of leftovers.
No more bulky, energy-hungry, useless kitchen appliances for me!
