German Lip Salve, 1863

 Finally, reasonably-sized cosmetic receipt: 

GERMAN LIP SALVE Butter of cacao 1/2 oz., oil of almonds 1/4 oz.; melt together with a gentle heat and add 6 drops of essence of lemon. 

--The Druggist's General Receipt Book (1863)

For once, I didn't scale anything down. Just weighed out a half ounce of cacao butter, measured 1/4 oz almond oil (1/2 Tbsp), and heated them together in my makeshift double boiled (a glass bowl set in a saucepan of water on the stove). The lemon was essence stirred in after taking it off the heat, then the mixture was poured into 2 small tins (~1/2 oz each) to cool. 

Chocolate-scented lip salve.

This is one of the few mid-19th century recipes I've seen which calls for cacao butter rather than animal fat or beeswax, so I was eager to see how it would turn out. The cacao has a lovely chocolate scent and is distinctly yellow in color. Similar receipts mostly use white solids--lard, suet, tallow, white wax--so I did start to wonder about the intentionality of this yellow fat being used in this particular recipe, which does not add a coloring agent. I also started wondering if the recommendation to scent it with lemon essence was related to the yellow cacao butter. 

As it happens, the chocolate aroma from the cacao completely overwhelms the lemon, so this is mostly just a fun chocolate-scented lip salve.
