In the dehydrator I have done onions overnight. It definitely causes you to keep your nose in the pillow.

In the crockpot I've made Apple Butter which included Apple Cider in it and it simmered for several days. The aroma just drove me crazy. Turkey or Chicken Stock have also been simmered all night.

I'm having visions of tomato puree.......

best puree ever!

I'm not a sleeper - so its not unusual for me to be baking in the middle of the night - been like that all my life -

I have dried onions, garlic and tomatoes in the dehydrator over night. Basil and other herbs I have dried on low over night. I have left lots of things in the crockpot to cook over night and some of it has def made it hard to sleep. Apple butter is probably the most pleasant smelling thing I have made over night. I am a very light sleeper any way lol.
My brother was here the other day and he said the kitchen always smells good. I told him there is probably a permanent garlic smell in these walls now lol.

Yeah Cookie, modern convieniences are certainly SWEET!!! I think the one I most want but have never broke down and bought one is the Robot Vaccum Cleaner, really way too cool!!!!!! Vaccums the house while you are at work:D Gotta love the guy or gal who invented that!
