  • 200g wholemeal flour
  • 100g butter
  • 1 egg yolk
  • For the filling:
  • 2 medium onions, sliced
  • 2 cloves garlic, crushed
  • 200g hot-smoked trout, flaked
  • 150g watercress, chopped
  • Small bunch chives, chopped
  • 6 eggs
  • 200ml double cream
  • 2tsp garlic & horseradish mustard

To decorate:

  • 100ml double cream
  • 2tsp garlic & horseradish mustard
  • 20g cold smoked trout
  • Small bunch of chives

l Rub the butter into the flour with a pinch of salt. When the mixture resembles fine breadcrumbs, add enough cold water to bind into a pliable dough.

l Rest in the fridge for 20 minutes, then roll out on a floured surface and use to line a 25cm flan tin, leaving the edges to overhang until after the initial cooking. Prick all over with a fork, brush with egg yolk & bake for 10 minutes at 180c / GM4. As soon as it comes out of the oven, use the rolling pin to roll over the top of the tin - this will neatly trim the pastry edges and give the tart a professional finish.

l Fry the onion & garlic in butter until golden and sticky, then season and sprinkle over the pastry base. Top with the smoked trout, then add the watercress and chives in an even layer.

l Whisk the eggs with the cream & mustard, season with salt & white pepper, then pour gently over the tart. Bake for 15-20 minutes - it is ready when the centre is set, but still has a moist springiness. Leave to cool.

l Whisk the cream with the horseradish mustard and salt and white pepper to taste until stiff. When the tart has cooled, cut into thick wedges and decorate each one with a teaspoon of the cream, a morsel of smoked trout & a little tuft of chives.
