Alexander
Shake with ice and strain into a pre-cooled cocktail glass.
The original receipe was made with White Crème de Cacao, but Brown works also quite well.
Garnishing with grated nutmeg was not part of the original receipe (which resulted in a plain white cocktail), but is common today.
There are many variants in terms of the ratio of the ingredients. Most common is an increased amount of gin.
The Alexander is the ancester of many of todays famous cocktails, like the Brandy Alexander, the Grasshopper, the Golden Dream or the White Russian. The receipe was first mentioned in Hugo Ensslin's Recipes for Mixed Drinks in 1916.
One legend says that the Alexander was created to celebrate the advertising character of Phoebe Snow, who was dressed completely in white.

Curated this: removed references to fresh ingredients - that's assumed here at Kindred Cocktails. Changed amount of cardamom powder from dash to pinch. Changed amount of tamarind from dash to teaspoon (I'm guessing you want a small amount of tamarind paste muddled with the ginger).
When you say "shake with ice in batches", do you mean that all the liquid is batched, then shaken over fresh ice for each drink? Are the muddled ingredients meant to be quartered and added to each fresh shaker? Thanks, Zachary
