I love bone marrow all the way, i even proudly said that i literrary grown up with it. My mom used to make a hearthy and comforting broth out of it and made it into Pindang Tulang (Hot and Sour Beef Bone Marrow Soup). I think that’s why beef bone marrow is a traditional ingredient in certain cuisines around the world.  Beef bone marrow is high in certain nutrients, but it is also high in fat, so be creative and use it properly because the large ammount of calories on it, so work your butt out  once you consume  it. A single  14 grams serving of beef bone marrow contains 125.59 calories, eversince beef bone marrow is so rich and high in fat, a serving is smaller than a serving of other common protein items such as steak or fish.

Trust me, you’ll gonna love this spicy bone marrow crusted beef steak because it’s irresistibly delicious. My sister even eat the crust first before digging the tender and moist slow cooked sousvide beef striploin steak.

Enough for the bone marrow crust verdict, now were talking a sous vide beef steak method. Well, actually this is not the real fancy equipped sous vide method with sousvide waterbath circulator and vaccum sealed pack machine involved, instead this sort of sousvide method using amateur kitchen tools, but don;t worry, i take care all the basic principle of sousvide on this recipe. The black angus striploin beef seasoned well and sealed with ziplock bag to ensure no moisture loss out of it. The waterbath only act to transfer heat evenly and slowly to the beef steak. Why the heck of sousvide method??? it’s pricey and require lot’s of energy to do. The glorious of sousvide is about the very minimum ammout of moisture loose during the cooking, it create a very moist and tender steak, trust me, it’s worthed.

Sous-vide is French term for “under vacuum”, a method of cooking food sealed in airtight plastic bags in a water bath or in a temperature-controlled steam environment for longer than normal cooking times for up to 96 hours, in some cases; at an accurately regulated temperature much lower than normally used for cooking, typically around 50°C (131 °F) to 60 °C (140 °F) for meats and higher for vegetables. Sous vide also used to pasteurized egg, beef and other meat to made it save to be eaten raw without cooking it. I pasteurized my beef tenderloin to make Yukhoe (Raw Korean Seasoned Beef Steak Tartare with Asian Pear).

Since this is sort of-sousvide, the beef sirloin is vaccum packed with ziplock manually without any vaccum machine by simply submerged the ziplock package under water partially to pushed away the air. The ziplock package silicone seal then zipped once the air removed from the bad. This ziplock bag submerging method is quite efficient to pushed the air from the bag. Choose the heatproof and foodgrade ziplog with a good sealing quality, cheap ziplock bag may burst out while and ruined your entire pricey batch.

I’m using my old rice cooker (warmer mode) for this sort of-sous vide cooking. As you can see from the photograph, my waterbath temperature was 59.1°C , but it’s actually fluctuated from 58-60°C if i put the lid on it, just perfect temperature for sousvide beef sirloin for medium done. I let the beef steak sit in the rice cooker waterbath for about 2 hours, don’t get hesitate to leave it longer int he waterbath because it’s not a single chance your steak will overcooked. The heat source of my rice cooker is on the bottom of the metal container, so the temperature in the bottom and the surface of the the water bath is different with about 0.5°C range, so it’s necessary to flip it every 20-30 minutes to made the sous vide steak evenly cooked. Do not forget to submerged the vaccum packed beef sirloin completely on the waterbath during the sous vide cooking, putting some weight may help.

This is what sirloin steak sousvide in 58°C for about 2 hours look a like, it’s definitely not fancy looking at all, but wait until you see what’s happen on the inside. The sous vide beef sirloin fat is tender and the meat part looks pale and greyish, totally unpleasant for my eyes.  The texture of the beef is still medium done bouchy with a little pinkish juice color in the middle. Note the very little ammount of juice running out of the steak, i guess it’s a good sign that not much moisture driven out during the low heat and slow cooking. I set aside the juice from the plastic bag and served it later with the steak.

The sousvide sirloin steak then seared in a sizzling and smoking hot pan until browned for about 1 and half minutes each side until the  surface had a nice brown color. A little ammount of avocado oil or other high smoke point oil added into the pan heated until smoking hot and then the fat cap of the sirloin steak rendered first before searing the meat side. Now the seared sousvide striploin steak looks delicious, and i also observed that very little ammount of juice running out of it once i  resting it after pan fried. The striploin steak consist of  Longissimus Dorsi  (large part) and Longissimus Costarum (the small part) muscles, i cut the Longissimus Costarum to let you know what’s happen inside of the sous vide steak.

Look out the sagital cut of sousvide steak, it’s evenly cooked from edge to edge of the flesh, to exactly the doneness you want. The sous vide had perfectly throughout doneness, the meat has begun to turn pink and significantly firmer. Moisture loss is still minimal and the marbled  intramuscular fat has began to render, which not only lubricates the meat, making it taste juicier and more tender, but it also delivers fat-soluble flavor compounds to the tongue. My first verdict of it, damn!!! this is the most tender and juicy steak i ever had, cross my finger!!!!

Now we should compare the sousvide steak with my previously common grill pan Recipe Wagyu Ribeye Beef Steak with Creamy Green Peppercorn Sauce. Look out the central cut of the common grill pan steak you’re cooking with old school sizzling hot pan. This pricey wagyu ribeye had several level of doneness from the edge to edge, the edge of the steak reach much higher temperature than you ever want your food to reach and turn into overcooked and tough grey mess if you leave it a little bit too long in the pan And, even if you do achieve a medium-rare interior, the high heat environment of traditional cooking creates bands of overcooked areas around the outside. So, please use a slow cooking method from now on!!!

Now were making the bone marrow and herbs crust for the steak, while the steak is slowly cooked int he rice warmer waterbath, shall we begin to prepare the herbs for the bone marrow crust. The dryness of the ingredients is the key of making perfectly crispy crust. Any remaining moisture can made a diaster and ruined the crust layer and turn it into soggy and mushy disaster. Completely drained and carefully pat dry the fresh green herbs ingredients; the basil and chives, with kitchen towel first after you washed it with running tab water. You can use dried herbs instead, but the color isn’t as favoured as the fresh herbs.

I infused the crusted layer for the steak with fresh lemongrass, onion, garlic, chilies, lemon basil leaves and garlic chives. All the ingredients is finely chopped, i suggest to pat it dry further more with kitchen towel. Please do it carefully, make sure you absorb the excess moisture of it before mixed with breadcrumbs and bone marrow.

The bone marrow extracted from the bone then put it in the freezer until frozen, finely diced and mixed it quicly with the breadcrumbs and the the chopped mixed herbs. The bone marrow crust mixture then spreaded over a plastic film, rolled until had an even thickness and  sufficient to cover the beef steak. The bone marrow and herbs crust then transfered into freezer once more until firm and ready to use.

The firm chilled bone marrow crust placed over the seared beef steak and then broiled in the preheated oven using the high heat about 250°C for about 3 minutes and then lower the temperature to 200°C for another 5-7 minutes until the bone marrow crust browned and crispy.  You can adjust the position of the crust in the oven to let the bone marrow crust evenly cooked.

This is the bone marrow crusted sirloin steak freshly broiled out in the oven, the rendered bone marrow fat dredged the beef steak in the botton of the oven tray. You can scoop it out, mixed it with the juice from the sousvide bag and served is as a sauce for it.
