Wow, DD, that is indeed no yolk! What a scary thing to happen! So glad everything has worked out and hope that it continues to do so for you.
I had a TM5 demo fully expecting to think I didn't need it. i fell in love with it immediately as did my sister who was most determined not to love it at all!! I'm really loving it and using it multiple times a day. Love the recipe chip especially, something I thought I wouldn't like at all.
Re the egg whites. I often find I have left overs too. I forget about them and they lurk in my fridge. Friends is a good suggestion. Egg yolks can be kept in the fridge for a while if you put them in water, apparently.
