The typical English High tea usually involves a cup (mug) of tea, bread, cheese, vegetables and some meat too. I did a search on the web to find out more about high tea. One possible reason I found states that "this type of meal was called high tea is the fact that it was eaten at a table", whereas afternoon tea is more casual and taken on sofas and comfortable chairs.
That afternoon, C and I did not have a cup of tea, bread, cheese, vegetables and meat. Instead, we started out with a glass of sparkling wine, followed by crustless finger sandwiches with four different fillings - roast beef with horseradish and baby cress; smoked salmon with rocket, lemon and capers; cucumber with cream cheese and chicken with wild herbs. The next tier had the sweets - lemon cheesecake, chocolate mousse cup, vanilla cupcake with passionfruit icing and fruit tartlet. On the top tier were the two scones which we had each selected - C chose the white choc and cranberry and I chose the lemon, pistachio and currant.
