I’m crazy. Does the name ring a bell? If the answer is no, we’ll tell you. An entrecula is a cut of beef, also known as “butcher’s brisket”. A small piece that has no appetite that, on the contrary, is super juicy and precious. It comes from the animal’s diaphragm and is very tender.

Precisely because of its tenderness and taste, It’s the part that Karlos Arguiñano uses to prepare his homemade hamburgers. but the chef mix the minced meat with an ingredient you would never imagine: cooked rice! The reason is that the rice makes the burger even juicier.

We saw it on the Antena 3 program Open Kitchen, and although the chef did not give the quantities of the ingredients, we provide them so that you can prepare these delicious hamburgers at home.

In addition, while preparing the meat mixture, Karlos Arguiñano cooks some roasted potatoes with spices that are a real miracle. And we also tell you how they are made.
