Floriade Recipes: Mandarin, chick-pea cake, blueberry spelt muffins, homemade buttermilk and homemade baking powder

I'm doing a few shows at the fabulous floral festivos of Floriade again this year. In the 'Tasting Plate' kitchen under the theme 'The other flour festival' I cooked up some treats. Here they are. Good luck with them and let me know how you go.
MANDARIN AND (SNEAKY) CHICK-PEA CAKE
Here is the fabulous recipe from Chrissy Freer's book 'Super Legumes'. If you like the idea of incorporating the super vegetable into all manner of recipes, this is a great book.
