The other day, I was perusing Red Apron Butchery and saw that they had marrow bones. I LOVE marrow, but I had never made it at home before. It was time to fix that! You might be interested to know that while marrow is made up of fat, it is largely unsaturated; plus it has lots of vitamins and minerals like iron and Vitamin A, and it has been shown to boost the immune system!
Now you actually want to soak these bad boys in salt water overnight to draw out the blood. It's not going to kill you or anything if you don't, but it won't taste as good.
Then you just pop them into a hot oven and roast for 20 minutes. You could just sprinkle it with coarse salt and eat it with a spoon, I wouldn't blame you. But if you want the full experience, spread it onto some toasted challah bread and top with a tangy parsley salad to balance out the rich fattiness. Prairie butter, poor man's foie gras, pure heaven - whatever you want to call it, this stuff is delicious decadence.
Roasted Bone Marrow
8 3'-4'-long pieces beef or veal marrow bones (cut lengthwise or crosswise, doesn't matter)
1 cup fresh flat-leaf parsley, roughly chopped
2 small shallots, thinly sliced (about 1/3 cup)
2 tbsp extra-virgin olive oil
1 tbsp fresh lemon juice
1 tbsp drained capers
Coarse sea salt and freshly ground black pepper
4 1/2-inch thick slices challah or rustic white bread, toasted
To remove the blood from the marrow, place the bones in a bowl of ice water with 1 tsp coarse sea salt per 1 cup water. Refrigerate for 12 to 24 hours, changing the water every 4 hours and replacing the salt each time. Drain and refrigerate until you are ready to cook the marrow. Be sure to use it within 24 hours or freeze the drained bones for up to 3 months.
Preheat the oven to 450°. Place bones in an ovenproof skillet or roasting pan - wider cut side down for crosswise, cut side up for lengthwise. Roast bones until marrow is soft and begins to separate from bone but before it begins to melt, 15-20 minutes, depending on thickness of bones. Sprinkle with sea salt.
Meanwhile, toss parsley, shallots, oil, lemon juice, and capers in a medium bowl to coat. Season salad to taste with sea salt and pepper.
Serve bones with toast and parsley salad. Use a long, thin spoon or knife to scoop marrow onto toast and top with salad.
