Ingredients
- 1 1/2 lb beef chuck, cut into 1-inch cubes
- 8 oz lamb kidneys, trimmed and cut into pieces
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1/3 cup all-purpose flour
- 2 tbsp vegetable oil
- 1 large onion, diced
- 2 tbsp tomato paste
- 1 tbsp Worcestershire sauce
- 2 cups beef stock
- 1 tsp dried thyme
- 1 bay leaf
- 1 lb puff pastry
- 1 large egg, beaten
Instructions
Follow each step in order. The directions below are written so a beginner can understand what to do, what to look for, and when to move on to the next step.
- Step 1.Trim the kidneys carefully, removing the white cores, then pat both meats dry and season them evenly with the measured salt and black pepper.
- Step 2.Toss the beef and kidney with flour, shake away the excess, and brown the pieces in hot oil in several small batches so a dark crust develops.
- Step 3.Transfer the browned meat to a clean bowl, lower the heat, and cook the onion until soft before stirring in tomato paste until it darkens slightly.
- Step 4.Add Worcestershire sauce and beef stock while scraping the pan thoroughly, then return the meat with thyme and bay leaf and bring the mixture to a simmer.
- Step 5.Cover and cook gently for about ninety minutes until the beef is tender, then uncover and reduce the gravy until thick enough to coat the meat generously.
- Step 6.Discard the bay leaf, cool the filling completely, and spoon it into a deep pie dish because warm filling will melt the butter in the pastry prematurely.
- Step 7.Cover with puff pastry, press and crimp the edge securely, cut steam vents, and brush the top evenly with beaten egg for a glossy golden finish.
- Step 8.Bake at 400°F for 30 to 35 minutes until the pastry is fully risen and deeply browned, then rest for ten minutes before serving the hot filling.
