Place mandarines (skin and all) in SC and add water so they are just covered. I left mine on low for 7 hours, but they could be done after 2 on high. Allow to cool then drain.
Place mandarins and sugar in the food processor and process until liquid, add other ingredients and blend into a batter.
Line a 20cm cake pan or 25 cupcake pans. Poor batter in. I made 20cm pan plus 6 cupcakes from this quantity.
Bake for approx 1 hour in oven or until cooked or on low in SC for approx 2 1/2 hours (I haven't made the cake in the SC yet).
The recipe I adapted this from used fresh mandarins and coated cake in sugar glaze, slitered almonds and mandarins segments. I didn't do this but you could.
