Thanks all for the plum ideas @djyee100 @Thanks for the Crepes, @heidih, @kayb, @JoNorvelleWalker. And @Anna N that is the plum torte I mistakenly called plum cake. We've been out of town all week and the heat in Northern Calif ripened the plums. Picking, dehydrating and then freezing some until I have time to make jam/ chutney/something
