Beat butter and sugar in an electric mixer until pale and fluffy, then add eggs one at a time, beating well after each addition. Add honey, flour, polenta and ground almonds and stir to combine. Spoon into a buttered and floured 11cm x 21cm loaf pan, smoothing top. Bake in centre of oven until a skewer inserted into centre withdraws clean (1 hour 20 minutes).
