• Short crust pastry
• 500 gm onions
• 50 gm butter

Prepare the pastry pie shell and set aside in a cool place while you prepare the filling. Peel and slice the onions and place them in a pan with the butter. Cover and cook gently for 15-20 mins. Remove the lid and cook quickly until browned. Remove from the heat. Lightly mix the eggs and sour cream and stir into the onions and seasonings. Pour the filling into the base and cook in a moderate oven for 40-45 mins.
