In this guide, you'll learn the key steps to achieve a flawless texture and a sauce with the perfect consistency for four diners.

The key to success: the sealing and the vegetables.

To achieve meat that retains its natural juices and a sauce with depth of flavor, it is necessary to take care of two fundamental aspects during the initial cooking.

• The sealing of the meat: by cooking the sirloin in batches over high heat, we achieve the Maillard reaction, which gives that golden color and intense flavor to the surface, preventing the interior from drying out.
• The patient sofrito: gently poaching the onion and leek over medium heat allows the vegetables' natural sugars to caramelize slowly; this is the aromatic foundation upon which the rest of the ingredients will rest.

The master touch: the texture of the sauce.

Chestnuts are a versatile ingredient that not only adds flavor, but also acts as a natural thickening agent, giving body to any preparation.

• The trick of blending: separating a portion of the chestnuts along with some broth to process them and then returning them to the pot is the ultimate technique for obtaining a smooth sauce with a concentrated nutty flavor.
• Alcohol evaporation: it is essential to let the white wine reduce for a few minutes before adding the stock; this eliminates the sharp acidity of the alcohol and leaves only the fruity nuances that enhance the profile of the sirloin.

Ingredients

• 2 pork tenderloins
• 150 grams of chestnuts
• 2 cloves of garlic
• 1 piece of onion
• 1 piece of leek
• 150 milliliters of white wine
• 400 milliliters of broth or water with a bouillon cube
• 1 splash of olive oil
• 1 pinch of salt
• 1 pinch of pepper

Preparation

• Clean the pork tenderloins and cut them into uniform pieces about 2 to 3 cm thick. Season each piece with a pinch of salt and pepper.
• Heat a large saucepan with a generous drizzle of olive oil over high heat. Add the pieces of meat in batches to brown them evenly on the outside. Once seared, remove them from the saucepan and set aside.
• Peel and finely chop the onion and leek. In the same pan where you browned the meat, add a little more oil over medium heat and add the onion and leek. Let them soften for a few minutes, then add the garlic, either whole or chopped, being careful not to burn it.
• Peel the chestnuts. If the skin is very stuck, microwave them for a few minutes to make it easier to remove.
• Add the chestnuts to the casserole with the vegetables and brown them lightly, being careful not to burn them.
• Pour in the white wine and let the alcohol evaporate for a few minutes. Then, add the beef or vegetable stock and simmer the sauce over medium heat for 15 minutes. Season with salt and pepper.
• After this time, add the meat back to the pot. If you prefer your meat rare, cook it for 5 minutes; if you prefer it more well-done, you can leave it for up to 10 minutes.
• To give the sauce a thicker texture and a more intense flavor, remove some of the chestnuts and a little broth, blend them until you get a cream and add them back to the pot.
• Mix well and let everything blend for a couple more minutes.
• Taste the sauce to check the salt level and adjust if necessary before serving.

Enjoying this sirloin steak is an invitation to appreciate seasonal produce with a simple technique that highlights the quality of the ingredients. The combination of tender meat with the richness of chestnuts guarantees a nutritious and comforting dish that is always a hit at the table.
