  • Step 1

    Grease and line a square 20cm (8″) cake tin (or a loaf tin) and set to one side.

  • Step 2

    Melt 1 tablespoon of the butter in a large, non-stick saucepan and add the garlic paste. Fry for 1 minute then add the vegetable stock and bring to the boil.

  • Step 3

    Remove from the heat and rapidly whisk in the polenta until smooth. Return to the heat stirring until boils and thickens. Whisk in the remaining 3 tablespoons of butter.

  • Step 4

    Pour the polenta into the lined tin, refrigerate for at least 3 hours but preferably overnight.

  • Step 5

    Remove the polenta from the tin and cut into 1/2″ slices. You can cut into squares first then slice into smaller triangles or any shape you wish. Brush with olive oil and set to one side.

  • Step 6

    Insert the grill plate into the cooking pot. Select GRILL, set the temperature to HI, and time to 14 minutes. Press START/STOP. Once the pre-heat cycle has finished place half of the polenta into the grill. Close the lid to cook.

  • Step 7

    When the unit displays the ‘FLIP’ prompt open and close the lid. After 10 minutes of cooking carefully flip the polenta using silicone tongs and cook for the remaining 4 minutes. Repeat steps 6 to 7 until all polenta is cooked. Serve immediately.

    For a richer, creamier flavour replace the vegetable stock with milk and season accordingly.
