Just dropped in on your site for the first time. Read your remark about onions burning your eyes when you chop them (in the bialys recipe). I too have tried many things to prevent the inevitable crying when I chop onions. Nothing worked satisfactorily until I read this tip somewhere. Have you tried wearing safety glasses (don’t laugh) or sunglasses (if they’re fairly large ones)? This usually works for me and now I am no longer teary-eyed.

Happy baking!
