All you need to do is put onions in the fridge for a while before you use them. in fact l have always kept mine in the fridge and also have ready chopped ones in the freezer.
I have to agree with you, Crofton pans are really good quality. Better than ones l have paid four times the price for. My Crofton the deep glass lidded frypan, at $29.95 a real bargain.
I have to say that l waste very little. I freeze lots of things. Shallots, capsicum, celery, herbs, berries, cheese that l grate myself. And much more. I cook larger amounts of meals and freeze them in seperate containers.
