Knife was sharpened. Onions had the ends cut off and then straight into water to be peeled. They were then sliced in the food processor, which was opened under the exhaust fan to put into the pan. I managed to get away with only needing to wash my face to end excessive teariness once, which is pretty good for me as I seem to be very sensitive to onion.

I wish that was all it took. I am very sensitive to onion and end up in tears cutting them as a regular occurance. With large batches like this tears are guaranteed.
