Pour 1⁄4 l boiling salted water over polenta. Leave to stand for about 10 minutes. Peel garlic clove, chop finely. Stir 50 g of gorgonzola in pieces into the hot polenta. Smooth out in greased portion cups or pans.
Spread the rest of the cheese on top. To serve, bake in a hot oven (electric cooker: 225 °C/circulating air: 200 °C/gas: see manufacturer) for approx. 10 minutes.
