The Carmel Sugar
Is known by boiling yet longer, and is proved by dipping a Stick, as aforesaid, first in the Sugar, and then in the Water: But this you must observe, when it comes to the Carmel Height, it will snap like Glass the Moment it touches the cold Water, which is the highest and last Degree of boiling Sugar.
Note, There is this to be observed, that your Fire be not very fierce when you boil this, lest flaming up the Sides of your Pan, it should occasion the Sugar to burn, and so discolour it.
