How to prepare fried polenta crostini with mushrooms and Grana Padano fondue:

First, prepare the polenta: pour the water, oil, and salt in a high-sided pan and bring them to a boil. Then, slowly add the instant polenta flour while vigorously stirring with a wooden spoon to avoid lumps. Cook for about 10 minutes until it becomes fairly dense and compact.

Pour the still hot polenta onto a tray measuring 33×24 cm and spread it with a spatula until it reaches a thickness of 5 mm. To make it smoother on the surface, you can cover the tray with a sheet of parchment paper and level the polenta with a rolling pin. Put the tray in the refrigerator to set for at least one hour.

In the meantime, clean the mushrooms by removing the end of the stem with a small knife, then peel both the stem and the top. Finally, moisten a sheet of kitchen paper and gently rub to eliminate any residue of dirt. You will need about 250g of cleaned mushrooms.

Cut the mushrooms into thin slices, then chop the parsley and chives.

Slightly crush the garlic clove and fry it in a pan with oil for a couple of minutes, then add the mushrooms, parsley, and chives. Season with salt and pepper and cook over medium heat for about 5 minutes.

When it’s well-set, remove the polenta from the refrigerator and cut it into rectangles of 5×6 cm. Pour the semi-frying oil into a pan and heat it to a temperature of 160°C. Fry a few polenta rectangles at a time for about 3 minutes per side, then drain them on a sheet of absorbent paper.

Prepare the Grana Padano DOP fondue by pouring the milk into a small pot and bring it to a light boil. Then, add the grated Grana Padano DOP and cook over medium heat for about 10 minutes, stirring constantly with a whisk until it reaches a creamy consistency.

Now, you can assemble the crostini: pour a teaspoon of Grana Padano DOP fondue, garnish with a teaspoon of mushrooms and season with a pinch of pepper. Your fried polenta crostini with mushrooms and Grana Padano fondue are ready to be enjoyed!
