Norfolk Cockles

What have I thought about today?....

I`ve watched a programme about food along the Norfolk coast, watched them digging for cockles - that made me wonder - Who first found that you could dig up cockles, then cook them and eat them?!
Same with all our food, who first found it was edible? and how to cook it??
How many made theirselves ill by trying out things that were poisonous in the process?
We should be grateful to them, for the variety of good food we enjoy today

It`s a thought, isn`t it?!
