Maminha with Caper Sauce (Maminha ao Molho de Alcaparras)

Ingredients
3 lb (1.5 kg) maminha, in one piece
1 tbsp salt
2 cloves garlic crushed
3 tbsp capers, drained
2 tbsp extra-virgin olive oil
3 tbsp Dijon mustard
3 tbsp Italian parsley, finely chopped
3 tbsp green onion, green part only, finely chopped
3 tbsp fresh basil, finely chopped
3/4 cup creme fraiche or sour cream
 

Mix the salt and garlic in a small bowl with the back of a wooden spoon, or use a mortar and pestle to create a paste. Spread the paste on the top of the piece of beef and let it rest for 15 minutes.

Place the beef in a roasting pan, cover it with a lid or with aluminum foil, and put it in a preheated 350F (175C) oven. Remove the cover and continue to cook for approximately 15 minutes, or until the top is browned.

Meanwhile, put the olive oil in a medium-sized frying pan and heat over medium heat. When the oil is hot, but not smoking, add the capers and fry for one minute. Add the mustard, parsley, green onion and basil and stir to mix thoroughly. Turn off the heat, and slow add the creme fraiche or sour cream, stirring constantly to avoid lumps. When the creme is all added, test for temperature, and if necessarily return to heat briefly to heat the sauce through, but do not let it boil.

Remove the roast from the oven, place it on a carving board, and slice into 1/2 inch (1 cm) slices, cutting across the grain of the meat. Arrange them decoratively on a serving platter, and drizzle the caper sauce over. Serve immediately.
