Grass Fed N.Y. Strip Steak with Bone Marrow-Sage "Chimichurri"

If someone were to ask me to identify my favorite ingredient, I could quickly focus on a handful of ingredients. One of those ingredients is bone marrow.  The health benefits of bone marrow are still under study, but there are some preliminary findings that are very favorable.  Bone marrow is full of polyunsaturated fatty acids.  Those are the good type of fatty acids, as best demonstrated by one of the most well known polyunsaturated fatty acids ... Omega 3.  Bone marrow also contains iron, phosphorus and vitamin A.   However, the most interesting nutritional fact about bone marrow is that it contains alkylglycerols or AKG.  Alkylglycerols are a form of lipid that stimulate the generation of white blood cells known as neutrophils, which are cells of the immune system that defend against bacteria and fungi. AKGs are also believed to stimulate the production of microphages, which are immune cells that actually digest pathogens and foreign invaders.  

The common wisdom is that if something is that good for you, as bone marrow seems to be, it could not possibly taste good.  I am happy to say that this is where the common wisdom fails. In this recipe, bone marrow is used as a substitute for olive oil and sage is used for a substitute for cilantro and parsley.  The substitutions created a great flavor pairing ... bone marrow and sage ... that led to a great sauce to top a New York Strip Steak. 

A Chef Bolek Original
Serves  2-3

1 N.Y. Strip Steak, about 3/4 to 4/5 of a pound
3 marrow bones
1 teaspoon of pink peppercorns (substitute black peppercorns)
2 cloves of garlic, sliced
2 tablespoons of fresh sage, chiffonade
1 teaspoon of ground black pepper
1 teaspoon of ground sea salt
1/4 teaspoon of crushed red pepper

1.  Roast the marrow bones.  Set the oven at 425 degrees Fahrenheit.  Place the marrow bones in the oven and cook them for about thirty minutes.  Remove the bones from the heat and scoop out the marrow into a bowl.  

2.  Cook the strip steak.  Start the broiler.  Season the steak with salt and black pepper on all sides.  Cook the steak to the desired doneness.  

3.  Prepare the "chimichurri."  While the steak is cooking, add the bone marrow and the other ingredients (sage, black pepper, peppercorns, sea salt, crushed red pepper) to a food processor.  Use the food processor setting and pour in any liquid fat from the bone marrow.  (If there is no liquid fat, use about one to two tablespoons of olive oil.)  

4.  Plate the dish.  Slice the strip steak and spoon the "chimichurri' over the meat.
