How to eat your scone (or is it a 'scon'?) is more than just deciding on the cream/jam order. British etiquette includes knowing how to open the scone, how to add the cream and jam and then what to do after that (not just popping it in your mouth!).
Have you ever heard that expression before? It refers to preferring milk first in your tea, or tea first and add milk (if using it) after! But which way is the correct way? Which way is the 'posh' way?
