Some of the drinks my alcoholic anti-heroes put away during their treks around London sounded frankly delicious to me. Here are a couple of tap-room tipples you could enjoy in 1831:

Egg Hot: boil up in a saucepan one quart of strong ale, some sugar, cinnamon and a dash of lemon. Remove from the heat and add a glass of cold ale. In a jug, beat 6-8 egg yolks and add some sugar and nutmeg. Pour the ale into this jug and stir.

A variant was Egg Flip:
add extra eggs and cream to the above and then thrust a hot poker into the jug, making it bubble and giving a more bitter and burnt flavour.
For extra strength, add one or two glasses of gin and/or rum, as preferred.

If you really wanted to get out of it (or get somebody else out of it, in order to rob, assault or burke them), “locus-ale” was beer that had had laudanum (liquid opium) added in. The act of spiking someone else’s drink in this way was known colloquially as “to hocus” or “to locus” someone.
