Wikipedia: Horchata
Horchata or orxata is the name for several kinds of vegetable beverages, made of ground almonds, sesame seeds, rice, barley or tigernuts (chufas).
 
Etymology
The name comes from Valencian orxata, probably from ordiata, made from ordi (barley) (Latin *hordeata < hordeum). The French and English ‘orgeat’, the Italian ‘orzata’, and the Surinamese Dutch orgeade have the same origin, though the beverages themselves have diverged, and none of them are typically made from barley any more. One legend links the origins of the name to King Jaume I, who after being given the drink for the first time by a local in Alboraya, was said to have exclaimed “Això es or, xata!” (“That’s gold, girl!”)
 
Spain
In Spain, it usually refers to orxata de xufes (horchata de chufas), made from tigernuts, water and sugar.
 
Originally from Valencia, the idea of making horchata from tigernuts comes from the period of Muslim presence in Valencia (from the 8th to 13th century).
 
It has a regulating council to ensure the quality of the product and the villages where it can come from, with the Denomination of Origin. Classics get an A. The village of Alboraia is well known for the quality of their horchata.
 
It is served ice cold as a natural refreshment in the summer. Tigernut horchata is also used in place of milk by the lactose intolerant.
 
Latin America
While in some countries the drink is usually tan and “milky”, some recipes call for milk, and others do not. Other ingredients often include sugar, cinnamon, and vanilla. Though horchata was once typically homemade, it is now available in both ready-to-drink (shelf-stable or refrigerated) and powdered form in grocery stores.
 
In the US, rice-based or morro horchata is served in many Mexican restaurants, and the horchata de chufas (tigernut) is virtually unknown. Rice-based horchata is also sometimes available in US grocery and convenience stores, especially in Latino neighborhoods.
 
Horchata, together with tamarindo and jamaica, are the three typical drink flavors of Mexican aguas frescas.
 
In Puerto Rico, horchata is made of powdered sesame seeds, milk, cinnamon & vanilla.
 
The horchata found in El Salvador is often made of a mixture of herbs, not rice. The horchata is typically flavored with Morro (Calabash tree) seed, ground cocoa and cinnamon as well as sesame seeds, and in some cases is strained.
 
In Nicaragua and Honduras horchata refers to the drink known as semilla de jicaro, made from the Jicaro seeds ground up with rice and spices. The drink is made with cold milk and sugar and is very popular nationally. Recently Nicaragua has began exporting this product primarily to the United States.
