Chocolate and apricot sandwich cake
Instead of using buttercream or cream, use apricot jam to sandwich two chocolate sponges. The tartness of the jam works well with chocolate.
Fruit tart glaze
When making a fruit tart, such as a classic apple tart, apricot jam will give it a shiny finish. Warm a little jam in a pan with a splash of water then brush over the fruit, cool and put in the fridge to set.
