To Sweeten Rancid Butter.
Оглавление—I.—Wash the butter first with fresh milk and afterwards with spring water, carefully working out the residual water.
II.—Add 25 to 30 drops of lime chloride to every 2 pounds of butter, work the mass up thoroughly, then wash in plenty of fresh, cold water, and work out the residual water.
III.—Melt the butter in a water bath, along with some freshly burned animal charcoal, coarsely powdered and carefully sifted to free it from dust. After this has remained in contact for a few minutes, the butter is strained through a clean flannel. If the rancid odor is not completely removed, complete the process.
