1/4 cup (1/2 stick) unsalted butter
In a large (12-inch) nonstick saute' pan, melt the butter over medium-low heat. Add the pork and the garlic, and cook, stirring and breaking up the pork, until the meat is just cooked. Add the demi-glace and stir well.
Add the flour, oregano, salt, and pepper, and cook stirring, until the flour is cooked and the mixture bubbles.
Stir in the juices and sugar and raise the heat to medium. Stir constantly until the mixture bubbles and is thickened. Taste and correct the seasoning.
Spoon the pork onto a large platter and sprinkle with the chopped cilantro. This dish goes well with hot cooked rice.
