Roast butternut salad

Preheat the oven to 160°C and line a 23 cm cake tin with baking paper.
Combine the polenta, almonds, coconut and baking powder with the lemon zest.
Cream the butter and sugar until pale and fluffy. Add the eggs, 1 at a time, and beat.
Fold in the lemon juice and dry ingredients until just combined.
Spoon into the prepared cake tin and bake for 1 hour, or until a skewer inserted comes out clean. Cool, then pour over the glaze.
To make the lemon glaze, place the icing sugar in a bowl and add a little lemon juice at a time while beating into a smooth paste.
