Nicely done. Been doing this lots myself. Will throw most of it into my freeze dryer to save me the freezer space.

Freeze dryer? I've never used one. Does it become dry enough to store at room temp?
Fortunately I have a lot of freezer space & reducing the volume of the liquid conserves a lot. One of those blocks is enough for a huge curry or meat sauce.
I add it late in the cooking because it can burn on the bottom of the pot if left unattended. In this way you can easily do a taste comparison of the difference. It's a significant improvement - much fuller taste & better texture.
I find I don’t have to reduce it as much because the freeze dryer eliminates all water. I’m left with powdered bone broth I then store in mason jars. Good on the shelf for 30 years.
It’s nice to use as you do, and can further be useful to thicken soups or stews; because it’s a powder, it’ll soak up some water and thicken meals.
