Well, Prospero has had a good first day :)
This morning he made a lemon-cream meringue for a dinner party this weekend. Nothing too tricky, just whisking egg whites and then double cream. But it would have taken me forever by hand, it was lovely having Prospero do it! It is now in the freezer, looking gorgeous 
Just made fairy cakes, going to taste test soon. I only did a 1 egg/2oz mix (as I really didn't need to make cakes, just wanted an excuse), and I did notice when I licked the K-beater washed up that there was some butter/sugar mix still on the beater, hadn't fully mixed in.
I usually use marge, but had butter in, so used that instead - could this have been the reason? Or just too small a mix (= excuse to make lots of cakes next time)
