PWB, I have not yet made bagels, but I always work on the principle that if the ingredients are not poisonous, what you bake won't be either. Give it a whirl. Most failures can either be sliced very thinly and toasted (bread), or eaten hot with custard (cakes). One should never be scared of baking, provided you have time to have several attempts. Don't try something complicated for the first time when cooking for a wedding!
I think since I've had DC and currently pregnant, all baking has gone out the window and I've lost my confidence I think. I will definitely give it a go as I am possibly slightly addicted to cinnamon and raisin bagels!
