Cakes are best the day you make them; leftover cake is great for breakfast the next day. (This is their tip) You can use plums, apricots, nectarines or peaches according to the recipe. I expect pineapple would work well also and pears would probably work too. I forgot the butter dots on the cake top and I didn't miss them. The recipe advises to use fruit that is just shy of being fully ripe- not hard but not soft. The apricots I used were a little over-ripe and they were awesome however.
