Begin by preparing the dough. In a bowl, combine the all-purpose flour, salt, sugar, turmeric powder, cold butter, and beef fat. Mix these ingredients well.

Gradually add ice-cold water to the mixture until a dough forms. Once combined, wrap the dough in plastic wrap and refrigerate for 35 minutes.

While the dough chills, heat two tablespoons of oil in a pan over medium heat. Add the finely chopped onion, minced garlic, and chopped sweet pepper to the pan.

Stir in the fresh thyme and chopped scotch bonnet pepper, followed by the chopped cherry tomatoes. Cook for a few minutes until the vegetables soften.

Next, add the ground beef to the pan and break it apart as it cooks. Season the mixture with allspice, black pepper, and salt.

Pour in the beef broth, soy sauce, and Grace Browning, mixing everything together thoroughly. Allow the mixture to simmer for a few minutes.

Once the beef is cooked, stir in the breadcrumbs, blending the mixture gently to combine without over-mixing.

After the dough has chilled, roll it out on a floured surface. If desired, add a bit more butter to the dough before rolling it out again.

Place the beef filling onto the rolled-out dough, then fold and seal the edges to form the patties.

Preheat your oven to 375 degrees Fahrenheit. Arrange the patties on a baking sheet and bake them for 30 minutes until golden brown.
