So, I am growing eggplant/aubergines for the first time successfully (bees love the flowers which is a huge bonus - the plant is on a sill outside the window by the dining table so we get to watch the bees come and go over meals). However, not sure when to harvest. Fruits are about ..well... egg size just now. Are they like courgettes in that smaller fruits are more tasty, or should I let them grow more? Should say that for us, taste is more important the quantity of crop.
