However the bulk of my knowledge came from my family, in particular my grandmother and mother and from not being afraid to experiment and try things out. I grow vegetables and fruit, I keep hens and ducks and pigs. I cook, bake, preserve, brew. I give children's cookery classes and tutor adults on a professional cookery course (nutrition and food science). Teaching children has been the best experience to date. To hear an eight year old repeat stuff I have said in a lesson to her mother really gives me a thrill. To be honest I don't think they are even listening half the time but this just shows they do. Teach the children and you will educate the world.
