Sorry George i just put the Base Gravy in freezer bags, i use two measuring jugs to do this.
I put a freezer bag inside one jug & use the second jug to pour the Base Gravy in until it gets approximately the 500 ML mark.
The spoons are all just slightly heaped,remember because of the large quantity of the Base you don't have to be exact as your margin for error is so large etc..
Hope this helps.
