Ingredients

Onion Filling:

  • 2 pound red onions or other onions, peeled, sliced
  • 1 cup balsamic vinegar
  • 1/2 teaspoon honey
  • salt and freshly ground pepper to taste
  • sprig chervil and a little reduced balsamic vinegar, for garnish

Pastry:

  • 1/2 cup whole wheat flour
  • 1/2 cup plus 2 tablespoons all-purpose flour
  • 1/4 cup oatmeal (not instant or 5 min)
  • 2-1/2 ounce softened butter
  • 3/4 cup shredded Swiss cheese
  • 3/4 teaspoon salt
  • 3 tablespoon cold water

Blue cheese topping:

  • 4 ounce soft blue cheese
  • 2 tablespoon plain yogurt

Preparation

To prepare onion filling:

  1. Place onions and vinegar in heavy saucepan. Cover with wax paper and lid. Cook gently for 30 minutes.
  2. Remove lid and paper, add honey and cook until liquid has almost evaporated. Season to taste. Keep warm.

To make pastry:

  1. Blend flours, oatmeal, butter, cheese and salt in blender until consistency of fine crumbs. Add cold water and form a ball.
  2. Let pastry rest for 30 minutes, and then roll out. Line six 4 inch round fluted tins with pastry, prick with a fork, and then allow pastry to rest for at least 30 minutes in the refrigerator. Preheat oven to 325. Bake tarts until pale golden brown.

To prepare cheese:

  1. Mash blue cheese with a fork and blend with the yogurt.
    • Remove warm baked pastry tarts from tins; place on large warm plates. Fill each with enough red-onion mixture to cover base, and place 1 spoonful of blue cheese mixture on top.
    • Garnish with a drizzle of reduced balsamic vinegar and chervil sprigs.
