Add this to your list of things to NEVER DO with a grease fire.
NEVER PUT WATER ON THE FIRE! The water will boil, blow the now burning grease everywhere and the fire will flare up real bad.
A thing TO DO...Keep a large box of BAKING SODA where you can throw it on the fire. It will smother the fire and create CO2. Just make sure you don’t tell Al Gore!
We always had the BRB (Big Red Button) if things got out of hand, but covering it with a metal lid, removing the heat and retreating generally worked. Hand held over the BRB, poised to run out the door like the wind.... waiting to see if the fire was actually going out.

Baking soda has always been beside the stove. That was also Lesson #1 for my 4-H kids.
