Lemon and Lime roulade

This lemon meringue roulade is a Mary Berry recipe, she has a really great book for Aga baking. Although we haven't devoured it yet (it's perfect for freezing) we trimmed off the edges to make it look better and they tasted yummy! It's a plain meringue baked with flaked almonds sprinkled on top then a lemon curd filling with lime zest.
