I can't remember where I found the recipe this is based on but I'm fairly sure it was one I found while trying to use up an enormous glut of courgettes. My Mum grows courgettes and apples so from August until the damn things die off we're inundated with them. Now I live away from my parents the effect on me is lessened but I still get the occasional vegetable delivery.

ABC stands for Apple-Banana-Coconut, which is the version I made for Ceilidh & Warwick's party but this recipe is pretty adaptable:
- I've used courgettes, apples, and carrots individually and in mixtures and they all worked fine.
- Walnuts are the classic choice of nuts but coconut works surprisingly well
- Dried cranberries or other fruit make for a sweeter & more exciting cake
- It's quite easy to turn this vegan as the only non-vegan ingredient is the eggs. I've made it several times successfully using flax eggs - one egg = 1tbsp ground flax (golden linseed) + 3tbsp water.
- I usually use brown sugar for the flavour
- C&W version had ~1/2tsp each of cinnamon, nutmeg, & ginger instead of the 1tsp of cinnamon
