Pink peppercorns are often used in savoury cooking, but they can work really well with sweet flavours too. This recipe combines them with tart, tangy rhubarb and a creamy cake batter to create an unusual but delicious sponge. This cake is great served cold with a cup of tea or warm with cream or custard.

Top Tip for making Rhubarb and pink peppercorn upside-down cake

Pink peppercorns aren't actually peppercorns at all! They're a type of dried berry, but get their name from their distinct peppery taste.
