Eliza Leslie,
Miss Leslie's Lady's New Receipt-Book…
“ TO PRESERVE LEMON-JUICE FOR A VOYAGE.—Select only the best and freshest lemons. One that is in the least tainted will spoil the whole. Roll every lemon under your hand upon a table to increase the juice. Then squeeze them well through a strainer. To every quart of juice add an ounce of cream of tartar. Let it stand three days, (stirring it frequently,) and then filter it through thin muslin pinned tightly on the bottom of a sieve. Put it into pint-bottles ”
