What sprung to mind over here were individual strawberry tarts - in fact, fruit tartelets in general - and possibly pavlova. I've never tried handling a slice of my pavlova while standing up drinking coffee, but it might just be possible <g>. Or you might be able to make individual pavlovas. Anyway, if you want the recipe for proper pavlova (as distinct from a normal meringue recipe), email me. It's a fantastically easy recipe, it's never failed me yet, it looks really festive and it tastes great.
I've also got three recipes for tray bakes (things you make in a tray and then cut into squares) together with something called chocolate logs which I haven't made in years but so far as I remember are pretty okay.
