Break into your preserving Pan the White of one Egg, put in four Quarts of Water, beat it up to a Froth with a Whisk, then put in twelve Pounds of Sugar, mixed together, and set it over the Fire; when it boils up, put in a little cold Water, which will cause it to sink; let it rise again, then put in a little more Water; so do for four or five times, till the Scum appears thick on the Top; then remove it from the Fire and let it settle; then take off the Scum, and pass it through your straining Bag.
Note, If the Sugar doth not appear very fine, you must boil it again before you strain it; otherwise in boiling it to an Height, it will rise over the Pan, and give the Artist a great deal of Trouble.
The boiling Sugar to the Degree called Smooth.
When your Sugar is thus clarified, put what Quantity you shall have Occasion for over the Fire, to boil smooth, the which you will prove by dipping your Scummer into the Sugar; and then touching it with your Fore-finger and Thumb, in opening them a little you will see a small Thread drawn betwixt, which immediately breaks, and remains in a Drop on your Thumb; thus it is a little smooth; then boiling it more, it will draw into a larger String; then it is become very smooth.
The Blown Sugar.
Boil your Sugar yet longer than the former, and try it thus, viz. Dip in your Scummer, and take it out, shaking off what Sugar you can into the Pan, and then blow with your Mouth strongly through the Holes, and if certain Bubbles or Bladders blow through, it is boiled to the Degree called Blown.
The Feathered Sugar,
Is a higher Degree of boiling Sugar, which is to be proved by dipping the Scummer when it hath boiled somewhat longer; shake it first over the Pan, then giving it a sudden Flurt behind you; if it be enough, the Sugar will fly off like Feathers.
