Serves: 4 

  • 2 tablespoons fresh or dried wholemeal breadcrumbs
  • 2½ cups (350 g) instant polenta
  • 1 teaspoon mustard powder
  • 400 ml boiling water
  • 2 large eggs, separated
  • 420 g can corn kernels, drained
  • 8 spring onions, chopped
  • 2 tablespoons snipped fresh chives
  • ⅔ cup (75 g) coarsely grated mature cheddar cheese
  • 150 ml buttermilk

Preparation:25min  ›  Cook:45min  ›  Ready in:1hour10min 

  1. Preheat the oven to 220°C. Lightly grease a large ovenproof baking dish of about 2.4 litre capacity, then sprinkle the breadcrumbs around the inside of the dish, including the sides.
  2. Put the polenta in a large heatproof bowl and stir in the mustard, then pour in the boiling water and stir until smooth. Cool slightly, then stir in the egg yolks, corn, spring onions, chives and about half of the cheese. Add the buttermilk and stir to form a thick batter.
  3. Whisk the egg whites in a separate bowl until stiff peaks form. Beat 1 large spoonful of the egg whites into the batter to lighten it, then gently fold in the remaining egg whites.
  4. Spoon the mixture into the prepared dish and sprinkle the remaining cheese over the top. Bake for 40–45 minutes until the top is set and golden brown. Serve at once, straight from the dish.


1 portions vegetables


Buttermilk, a tangy cultured milk product, contains slightly less fat than low-fat milk. It is stocked next to the cream in the chiller cabinet at supermarkets. If you can't find any, you can substitute low-fat milk mixed with 1 teaspoon lemon juice and left to stand for about 5 minutes before using.


Boost the vegetable content by adding diced steamed carrots, sliced leeks or frozen peas (no need to thaw) with the corn in step 2.
