I was making fries and started a grease fire but luckily I always keep a box of baking soda on hand when I cook and I was able to quickly put it out.
That is super unfortunate, did you manage to save any of the fries by chance? 
I did, it was just one of many batches. I usually have to go through like 10 or so every time I make fries. 
I'm glad that you did not lose all of them, it would be terrible if you did all that work for nothing!
