The reason you should grow your own food to eat, is because it tastes better.
The pie above (and yes the photo could be better but we were too eager to eat the thing) was as local as it could get.

Blackberries from the garden
Apples from the tree in the garden
OK, frozen pastry from Sainsburys (c’mon gimme a break)

Made the best blackberry and apple pie I have ever tasted. Eating local food isn’t just for the hippy dippy types to drone on about at dinner parties. It really does make the food better.

You are only going to eat a finite number of pies before you die, so make everyone the best tasting you can. Growing your own food, making your own food really does taste better.
