Ratafia
Popular during the 17th and 18th centuries, ratafia is a cordial or liqueur flavored with kernels of cherries, apricots, etc., 1690s, from French ratafia (17c.), word of unknown origin, perhaps of West Indian Creole origin. Ratafia is sometimes used to refer to a bitter almond flavor, as in Ratafia Biscuits.
A ratafia was an infused alcoholic cordial water which was produced without distillation. The classic flavour was made from the kernels of apricot or cherry stones. As a result, the English sometimes called these drinks 'kernel waters'. Ratafia made from peach kernels was called persico, while that from bitter almonds was known as noyeau. They all have a sweet marzipan flavour like the Italian liqueur amaretto, which is in fact a ratafia. The crushed kernels were infused in brandy or aqua vitae for a couple of months before being filtered out and sweetened. There is a danger in trying to replicate these drinks, because the stones of these fruits all produce a small amount of cyanide when soaked in water! Be warned. It is much safer to make quince ratafia from La Chapelle's recipe.
The recipe quoted here is that of Vincent La Chapelle, master cook to the Duke of Chesterfield in the 1730s. La Chapelle first wrote The Modern Cook, in English while in Chesterfield's employment. A French edition was published in 1735. It is one of the great eighteenth century classics and had a strong influence on upper class food in England. To some degree, La Chapelle borrowed some of his recipes from his predecessor Massialot, who composed a book on court cookery and confectionery in 1692. Massialot included a recipe for a ratafia flavoured with the juice of muscatel grapes and orangeflower water which is still made in some villages in Champagne and Burgundy.

From Vincent la Chapelle, The Modern Cook (London: 1733)
Recipe for Ratafia from Robert's Guide for Butlers & Other Household Staff, published in 1828.
Into one quart of brandy pour half a pint of cherry juice, as much currant juice, as much of raspberry juice, add a few cloves, and some white pepper in grains, two grains of green coriander, and a stick or two of cinnamon, then pound the stones of cherries, and put them in wood and all. Add about twenty five or thirty kernels of apricots. Stop your demijohn close and let it infuse for one month in the shade, shaking it five or six times in that time at the end of which strain it through a flannel bag, then through a filtering paper, and then bottle it and cork close for use; you can make any quantity you chose, only by adding or increasing more brandy or other ingredients.
