The year I had courgette-a-geddon, I did loads with them. Including courgette cake (which was very very tasty!! and not at all courgette-like), lots of stuffed courgettes and marrow chutney. (Please don't ask for recipes - I think I got most of them through people on the Grapevine - the forum on the website of a veggie gardening and allotment magazine, possibly called "Grow Your Own").
My bought yellow courgette plant is trying to set fruits - but there's no male flowers yet (usually it's all male flowers and no females for me!). But if I get lucky, I'll get 1 male, hand pollinate, and have a handful of courgettes before I go on holidays, perhaps a couple on my overnight in the middle and another glut when I get back.
I also hope to get a couple of peas (a handful of pods have emerged) and some strawberries before we go. Nicely early in the season this year.
It's amazing watching the back garden thrive this year - better than the past 4 years at least. I've been doing a LOT of watering at night, and I need to start feeding this week as well (normally it's mid-July before that happens). My main gripe is with my window-box of dwarf French and dwarf broad beans - they keep keeling over and dying off. I have 2 French plants, and down to 4 broadies - having started with 9 frenchies germinating and about 12 broadies.
Sorry to hear about your MIL Cupcakes, I hope the next while goes ok for the whole family.
