Hey esshup, we boiled down 8g of black walnut sap to syrup. keeping to the math that turned out to be 5 8oz bottles of syrup finishing at 218F, filtered twice (once off the outdoor stove and the second into the bottle indoors using doubled over cheesecloth both times).
One could boil farther, more water than what I thought but I stayed to the temps and holy cow get out the vanilla ice cream, it's butterscotch. Maybe a hint of walnut but, it's butterscotch.
Enjoy the rest of the season.
