Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
Make the base
In a large pot, combine the strong beer, molasses, and brown sugar.
Simmer the mixture, skimming off any scum that rises to the surface.
Flavour and bottle
Dissolve the tartaric acid in the water.
Add the dissolved tartaric acid and the essences of lemon, wintergreen, and sassafras to the pot.
Bottle the mixture, cork it, and secure with twine.
