Rhubarb, almond and polenta cake

IMG_2529In future, do you think historians will be able to use the number of cakes baked as a measure of how happy and secure people were feeling? Cake is a reassuring treat in times of anxiety, not just for celebrations. If so, Bake Off, cupcake mania and the explosion of cake recipes in the blogosphere carry a clear message about a nation in need of comfort. On the upside, we are getting to eat a lot of cake!

Today’s contribution to cheering us up is a variant on Nigella’s Rhubarb Cornmeal Cake from How to be a Domestic Goddess. I had a small amount of rhubarb that needed eating, and thought that this cake might be even nicer if I replaced the flour in the original with ground almonds (which also makes the cake gluten-free – use GF bicarb if necessary) – so this baby Rhubarb, almond and polenta cake was born. And it gave us an excuse to use Irene’s dinky cake forks, which come from Cecil, the restaurant her grandparents used to run in The Hague.

I had around a third of the quantity of rhubarb specified in the original recipe, so divided the original quantities roughly by three: Nigella uses 500g rhubarb and 2 large eggs for a 23cm cake tin. These quantities were just right for a 15cm tin.

160g rhubarb
100g caster sugar (I used 50.50 sugar and xylitol)
50g ground almonds
scant ½ tsp bicarbonate of soda
pinch of salt
55g fine polenta
scant ½ tsp ground cinnamon
1 medium egg
scant ½ tsp vanilla essence
40g soft unsalted butter
80g natural yoghurt

Preheat the oven to 180ºC/165ºC Fan/Gas 4. Butter and line the base of the cake tin.

Wash and trim the rhubarb, pulling off any strings as you cut off the ends. Slice into 0.5cm pieces, put into a dish and sprinkle over a couple of spoons of the sugar, and let it macerate while you continue with the recipe.

Mix the ground almonds, bicarb, salt, polenta and cinnamon together. Beat the egg and vanilla essence in a small bowl. Cream the butter with the remaining sugar. I did this by hand but, in retrospect, wished I had gone to the trouble of hauling the mixer onto the bench – it makes such quick work of the job.

Add the beaten egg and vanilla bit by bit, beating each addition in with a small spoonful of the almond/polenta mixture. Then lightly mix in the rest of the almonds and polenta alternately with the yoghurt. Finally, fold in the rhubarb with its juices, and pour into the prepared tin.

Check after 40 minutes and cover the tin with foil if the cake is getting very brown. Leave to cool a bit in the tin before taking it out.

Serve still warm with cream, with custard as a dessert, or just with a cup of tea.
