Edge of the American West has helped us catch up with the Angostura Bitters shortage of 2009–10, since we've been taking a bit of a break from the cocktail-shaking scene.

If only Angostura, now a division of Bacardi, were still manufacturing its concentrate for U.S. distribution in Jersey City, as it was at the time of a 1934 Talk piece about the secret recipe, protected by the evasive wiles of the then custodian, Alfredo Galo Siegert:

It takes eight months to make Angostura Bitters. "After the first four months, we do different things for the next four months," Mr. Siegert told us in a burst of confidence.

But you don't need fancy bitters to make an authentically pre-Prohibition mixed drink. The 1910 Siegert-sponsored Complete Mixing Guide at my elbow contains numerous recipes using the bitters, but also a ton of others, mostly with this rough structure:

WHITE PLUSH
Use whiskey glass.

Allow customer to help himself to bourbon or rye whiskey, then fill glass with milk.
