Polenta is an Italian store cupboard staple. This versatile ingredient finds its way into many savoury dishes replacing potatoes, rice and pasta. However, here I am delighted to be using our new yellow polenta to make a delicious citrussy sweet treat. Polenta is naturally gluten-free and gives its yellow colour to the cake, making it a vibrant centrepiece for afternoon teas and post-dinner indulgence. It is beautifully moist with a slightly grainy texture and just the right amount of zestiness. I think it is best served warm with a spoonful of mascarpone, drizzle of lemon syrup and a scattering of candied citrus peel.
