Treacle, syrup, and molasses are all products of the sugar-making process.
Borrowing from a couple of Wikipedia articles:
I also visited Ask.com to find some more answers--really a great site to find out stuff. :nod: This came from a link to BlurtIt.
I've got to take issue with one thing in this article because I think that there is a difference between treacle and molasses because treacle is thicker. This next bit from FunTrivia makes a bit more sense in that regard.
...........and, BTW, it takes approximately 40 liters (10 gal) of maple sap to be boiled down to 1 liter (1 quart) of maple syrup.
