OK, I have a few....

when cutting onions when your eyes really tear up--run some cold water and let your fingers rest in the stream--gets rid of the pain right away--have no idea why--but works!

Eggs--sunny side up--I hate over done eggs, heat pan, (never use nonstick), I use butter till it is bubbly but not burning the butter--a low/medium heat--crack the eggs into the pan, and turn the heat off--cover and they will be done to perfection in a few minutes and never over cooked!

Parchment paper--I love parchment paper--

I line pans, use on cookie sheets---makes for easy clean-up. Wrap fish in it to bake...

I use the non-bleached brown parchment paper.
