I have always thought stewed rubarb would be nice as a pav topper. But too lazy to try and make it! No, not true - we don't have an electric mixer and whipping egg whites by hand doesn't tend to motivate me.
Hee hee,

My brother did do one by hand once, he was sooo desperate to have a Pav! We all chipped in and took turns at the mixing and it tasted absolutely beautiful!!

NB: yes, my brother who's cooking exploits so far involve opening packets of pre-made meals actually cooked a pav!
