My sister's cake

There are many times I feel incompetant with myself.  When you see that fabulously skinny woman doing an hour on the cross trainer when you've done ten minutes on the treadmill and you're bright red and sweating is one that i invision quite vividly, however my sister (as sisters do so well) is able to outshine me quite profoundly when it comes to baking.  Even the simplest instant mousse recipe easily overcame my competence: one sachet you mix with milk, the other with water.  You'd think it would be hard to get it wrong, right?  But beside the point, any prospects of being a model have been quite firmly bodyslammed to hte ground with the fluffy raspberry and vanilla cake she produced.  Alas, all i could do in return was appreciate her heavenly masterpiece was to devour it, like a rabid dog.  Foaming at the mouth.
