Everyday open sandwiches are called madder in Denmark. We eat them casually out of our lunch boxes or in the evening, when we don’t want to cook a warm supper; a quick bite if we don’t have time for more. Good rye bread is vital both for texture and taste. It has to be the very dense, dark, sourdough type.

My favourite approach is to slice rye bread, boil eggs, find some leftovers, then dig some tomatoes and cucumber out of the fridge and fetch the fruit bowl. Prepare the toppings then arrange them nicely on boards and serving dishes, and all sit around the kitchen table to assemble the madder of your choice.

SERVES

four

INGREDIENTS

For the aubergine mayonnaise (makes 300ml, or enough for 20 servings)

  • 2 aubergines

  • 2 tbsp olive oil

  • 2 organic egg yolks

  • 1 tbsp Dijon mustard

  • 1 tbsp lemon juice

  • 1 tbsp white wine vinegar

  • 250ml flavourless cold-pressed oil

To serve

  • 4 slices of parma or serrano ham

  • 4 slices of rye bread

  • 4 medium tomatoes

  • 8 tsp aubergine mayonnaise

  • 4 tbsp watercress

METHOD

  1. Preheat the oven to 200C/Gas 6.

  2. Cut the aubergines into medium-sized cubes, skin on, and mix with the olive oil. Season. Bake for 20 minutes. Leave to cool. Turn oven to 220C/Gas 7.

  3. Whisk the egg yolks in a bowl, then add the mustard, lemon and vinegar and whisk together for five minutes. I prefer to use a food processor or electric hand whisk for this. Gradually add about half the oil, very slowly at first, whisking continuously, until thickened and emulsified. Continue adding the oil gradually, then whisk in the baked aubergines. Season with a pinch each of salt and pepper. Store in a sterilised jar in the fridge for up to one week.

  4. Meanwhile, place the ham slices on a baking sheet lined with baking parchment, and cook for eight minutes. Take out of the oven and leave to cool, then crumble them with your fingers.

  5. Place the bread slices on a worktop. Slice the tomatoes and place them on the bread, then place two teaspoons of the mayonnaise on each.

  6. Divide the crumbled ham on top, decorate with the watercress and sprinkle with black pepper.
