Meganjane, thanks for your help. Greatly appreciated.
I have made Thermomixer's Zucchini Cake - see http://thermomix-er.blogspot.com/2010/01/thermomix-zucchini-cake.html. Just tasted it and so so yummy! I had a similar situation as to what Thermixer says on the recipe - a neighbour gave me two massive zucchinis from their garden. Used almost one here and only used the outer flesh and skin. Recipe makes two loaves too. Hoping it should freeze ok.
