Kale and Pancetta Quiche

Sour Cream Pastry: In bowl, whisk flour with salt. Using pastry blender, cut in butter and lard until in fine crumbs with a few larger pieces. Whisk water with sour cream; drizzle over dry ingredients, stirring briskly with fork to form ragged dough. Press into disc. Wrap in plastic wrap; refrigerate until chilled, about 30 minutes. (Make-ahead: Refrigerate for up to 24 hours.)

On lightly floured surface, roll out pastry to generous 1/8-inch (3 mm) thickness. Fit into 9-inch (23 cm) glass pie plate. Trim to 3/4-inch (2 cm) overhang; fold overhang under and flute edge. Prick all over with fork. Refrigerate for 30 minutes.

Line shell with foil; fill with pie weights or dried beans. Bake in bottom third of 400°F (200°C) oven for about 15 minutes or until rim is light golden. Remove weights and foil; bake for 8 to 10 minutes or until pastry is golden. Let cool on rack. (Make-ahead: Cover and store for up to 24 hours.)

In skillet, fry pancetta over medium-high heat until crisp, about 5 minutes; drain off fat.

Add oil; fry onion and garlic over medium heat until golden, about 3 minutes.

Add kale and water; cover and cook until wilted, about 5 minutes. Uncover and fry for 1 minute. In bowl, whisk eggs, milk, cream, salt and pepper. (Make-ahead: Refrigerate pancetta and egg mixtures separately for up to 24 hours.)

Brush pastry shell with mustard; sprinkle with 1/2 cup (125 mL) of the cheese and the pancetta mixture. Pour in egg mixture. Sprinkle with remaining cheese. Bake in 375°F (190°C) oven for about 35 minutes or until knife inserted in centre comes out clean. Let cool on rack for 10 minutes. Cut into wedges.
