Root veg - fine, potato - roasting, old wrinkles. Otherwise, new is ok.
Carrot - young. Onion - ? Depends.
Bread I don't eat now, but generally, fresh on day - there is the odd bread that is good fresh and also good around 3 days later - you make yourself - the flour is very special, comes fro Privot ? Spelling in Launceston Tassie.
With fruit - orange is different - old is better than fresh - you need the skin to thin. _ it puts the sugars out of the skin into the fruit - it takes weeks for the process to complete.
