So it begins.....
Egg yolks cured and dried. I had to use the oven at it‘s lowest setting to finish drying them. One recommendation? Make sure you put a pretty thick salt/sugar base below the yolk before curing. A Dehydrator might be nice as well. They’re dry enough to grate now though.
Bone marrow cooked waiting to be scooped out. There’s a lot of bone marrow that is melted in the bottom of the pan, you want to use this too. It comes out cooked (and pretty tasty considering there’s no seasoning yet) with chunks.
I dug all the marrow out and drained the pan into a measuring cup. Since it was chunky I thought i should blend it with my immersion blender
This is the contents of three full bones. Roughly five ounces per bone. This will make

loads of butter. To bad y’all don’t live closer, I’d gift you some. I had a fourth bone (split). I stuck it into the freezer for my brother, he wants to make some as well.
So the ingredients call for two parts butter to one part bone marrow! So yes, that means 30+ ounces of butter....
Luckily I just so happen to have four eight ounce blocks. Yes, I know that’s three in the picture, I had a fourth in the fridge.
That leaves a little extra to use for basting the steaks while cooking tomorrow.
I‘ve got to do some clean up and let the marrow cool a bit right now before I do the blending of all the ingredients.
