There's a recipe if you click here. .
And all because of a conversation yesterday. They're a Scottish favourite, renamed Empire biscuits after World War I.
Two shortbread rounds, sandwiched together with jam, and iced - sometimes with a cherry on top. For a few minutes I was convinced the name was a corruption of 'Jam-on-biscuits', but the theory is that they are related to Linzertorte.
Meanwhile we ate a delicious aubergine and egg bake, and a Pavlova with raspberries, strawberries and blueberries. Many thanks to Alison and William for a lovely evening.
