Mary’s Christmas cake tips

Mary advises that for best results you make your Christmas cake at least 3 weeks ahead of the big day. If you’ve left it later than that, don’t panic – your cake will still taste delicious! When the cake is completely cold, wrap it in a double layer of greaseproof paper and then in foil and store in a cool place for up to 3 months. You can even freeze it. Decorate your Christmas cake with crystalised fruit, ribbon or stars – you’ll find icing ideas in the link below.
