Another way.
Pare a number of lemons according to the quantity you are likely to want; on the peels pour hot water, but more juice will be necessary than you need use the peels of. While infusing, boil sugar and water to a good syrup with the white of an egg whipt up. When it boils, pour a little cold water into it; set it on again, and when it boils up take the pan off, and set it to settle. If there is any skum, take it off, and pour it clear from the sediment to the water the peels were infused in, and the lemonjuice; stir and taste it, and add as much more water as shall be necessary to make a very rich lemonade. Wet a jellybag, and squeeze it dry, then strain the liquor, which is uncommonly fine.
