this recipe from Mark Hix with fine cornmeal. I also made a small amount of lemon syrup with the juice of the lemon and 2 tablespoons of sugar, to pour over the hot cake, which increased the lemony flavour.
I used an 8" round tin which was almost filled with the batter, giving some cause for concern. It did mean the finished cake was nice and deep though. Using the smallest suggested tin meant the cake took a few minutes longer to cook than suggested in the recipe - I think it was in the oven for nearer to 55 minutes, before I was satisfied that the centre was cooked, and I had to cover it with foil for the last 15 minutes. It sunk slightly in the centre, but not because of under-baking - there was no change in texture through the cake, which was very light. There were arguments here as to the stronger flavour - some thought it was a lemon cake, but the orange flavour was the stronger one for others.
I kept the cake plain, because I wanted to serve it as a dessert as well as a cake, but the lemon juice could have been used to make a glacé icing rather than a syrup. As a dessert, I served it with rhubarb and thick Greek yogurt again; I'm making the most of my home grown rhubarb!
