LadyMary I think the stir frying was my own invention, did you find anything googling it? Cubes of polenta, small broccoli florets, quorn (I suppose you could substitute chicken), lemon rind and garlic, I think I use sesame oil, then a bit of stock and lemon juice then a bit more stir frying.
My simplified version of Nigella's lemon polenta cake:
For the cake:
200g sugar
200g ground almonds
100g polenta
1.5 teaspoons baking powder
200ml light and mild olive oil (or other vegetable oil)
3 medium eggs
2 medium lemons (zest - save juice for syrup)
For the syrup (optional):
2 lemons
125g icing sugar
Preheat oven to 180g, grease a cake tin if not using a silicone pan. Combine the dry ingredients in a mixing bowl then in a separate bowl or jug, beat the eggs and add the olive oil, beat together. Pour the eggs and oil into the dry ingredients and mix to combine, add the lemon rind.
Pour into cake tin and bake for about 40 minutes.
For a truely sweet sticky cake, make the syrup by heating the icing sugar and lemon juice until sugar is dissolved then pierce cake with cocktail stick and pour over the syrup to allow it to soak in.
This cake can be sliced up when cool and frozen in pieces ready for packed lunches. It is quite sticky and crumbly with the syrup but utterly delicious, without the syrup is still worth making and easier to handle for a packed lunch.
Nigella may shop somewhere where ground almonds are sold in 200g bags but mine come in a bag of 150g so I use half ground almonds and half polenta.
