These hearty, golden-brown pasties are filled with tender, slow-cooked beef shin and smoky black beans, all encased in a unique cheesy mustard pastry. A perfect handheld meal for cozy dinners or outdoor picnics.
Set aside 2 tbsp of the flour and season it with salt. Toss the beef shin pieces in the seasoned flour until well-coated, shaking off any excess. Heat the vegetable oil in a large flameproof casserole dish and brown the beef on all sides for 5-6 minutes until deeply golden. Remove the beef to a bowl. Pour 50-70ml of water into the pan and scrape up the browned bits; if the liquid tastes savory and meaty, keep it in a separate bowl to add back later.
Add a little more oil to the dish if needed. Sauté the chopped red onions over medium heat for 10-12 minutes until they are soft and lightly golden at the edges. Stir in the grated garlic, chipotle paste, tomato purée, cumin, coriander, and chili powder. Cook for 3-4 minutes, stirring constantly, until the mixture is darkened and highly aromatic.
Pour in the chopped tomatoes and the reserved deglazing liquid. Rinse the tomato can with a splash of water and add that to the dish as well. Crumble in the stock cube and bring the mixture to a boil. Return the beef to the pan and reduce the heat to a low simmer. Cover the surface directly with a piece of damp baking parchment and cook on low for 2-3 hours until the beef is fall-apart tender. Stir in the black beans during the last 20 minutes of cooking. Allow the filling to cool completely before using.
To make the pastry, whisk the soured cream, English mustard, and one egg together in a jug. In a food processor, pulse the remaining flour and a pinch of salt with the cold cubed butter until the mixture resembles fine breadcrumbs. Add the grated Red Leicester and pulse briefly to combine. Pour in the wet ingredients and pulse again. Gradually add cold water, 1 tbsp at a time, until a soft dough forms. Tip the dough onto a floured surface, knead gently, then divide into two discs. Wrap and chill in the fridge for at least 30 minutes.
Preheat your oven to 200°C (180°C fan/gas 6). Remove the pastry from the fridge 30 minutes before rolling to make it easier to handle. Roll each pastry disc out into a thin sheet, approximately 0.5cm thick. Use a 16cm round cutter to stamp out 12 circles, re-rolling any pastry offcuts as needed.
Working with one circle at a time, spoon a few tablespoons of the cooled chili filling onto the lower half of the circle, then sprinkle with mozzarella. Fold the top half over the filling and seal the edges tightly, using a fork to crimp them. Beat the remaining egg and brush it over the top of each pasty. Arrange them on two large baking sheets lined with parchment paper and bake for 25-30 minutes until deeply golden. Serve warm or allow to cool fully for a picnic.
For the best results, make the chili filling a day in advance; a cold filling prevents the pastry from becoming soggy during assembly. If you don't have a 16cm cutter, you can use a small side plate as a template. These pasties freeze beautifully once baked and cooled—just reheat in the oven to restore the crispness.
