Hmmm, for me it depends whats available and what tastes the best.
Everything here is seasonal pretty much, with less choice of organic.
But its also expensive. e.g about £5 for two corn on the cobs.
Also the milk here is fantastic anyway, the swiss certainly do dairy well!
For Flint he gets what we are having - or frozen. But always well washed.
So in the end its a mix I guess.
