Trying to complete my catalogue for cooking products and am aware of certain items being unobtainable, but came across scrambled marrow and haven't seen it mentioned as a problem. Am I doing something wrong?

The recipe appears to be bone cream and one of the eggs (I used creature egg), but that does not yield scrambled marrow.

I have noticed that there was a previous bone cream that had the butter graphic, as opposed to the one I'm using that has the standard milk/cream graphic.

Does anyone know what the proper recipe is or is this a current bug?

Thanks!

In case anyone doesn't know, the "butter"-icon bone cream is made with bone milk and wild yeast. This bone cream can be added to a creature egg to successfully make scrambled marrow.
