Agua de horchata: what it is, how to make it and its taste

What is it?

Mexican agua de horchata is a refreshing white and creamy drink prepared with soaked and blended rice, cinnamon, sugar, milk and vanilla. Its sweet, mild and spiced flavour makes it one of the most iconic aguas frescas of Mexico. It is served daily in fondas, restaurants and markets across the country, forming, together with jamaica and lime water, the classic trio that accompanies everyday Mexican meals. Although it shares a name with the Spanish Valencian horchata (made with tiger nut), Mexican horchata is a distinct preparation, derived from the colonial substitution of tiger nut with rice, an ingredient abundant in American territory. It is consumed in all regions of the country with slight variants in the proportion of cinnamon and milk.

Origin and history

The horchata as a category has a Mediterranean origin: the Valencian tiger-nut horchata is documented from the thirteenth century in the Iberian Peninsula, derived from Arab drinks with almonds and seeds. The Spanish brought the concept to New Spain in the sixteenth century, but the tiger nut did not acclimatise well to Mexican territory. The colonial convents adapted the recipe by replacing it with rice, an equally starchy and affordable ingredient, giving rise to Mexican horchata around the seventeenth and eighteenth centuries. Larousse Cocina notes that the Mexican version is distinguished by the obligatory use of cinnamon and, in many regions, cow's milk. The addition of milk is relatively modern; in the traditional rural version it was prepared only with water and the prolonged soaking of the rice gave the natural creaminess. In Yucatán a variant is made with grated coconut; in Oaxaca crushed red prickly pear is added at the end, creating a white-red contrast characteristic of Oaxacan horchata.

Characteristic ingredients

Common white rice is the main ingredient; some recipes use brown rice for more rustic variants. It is soaked for six to twelve hours in cold water with a cinnamon stick to hydrate the grains and release the starch. It is then blended with all the soaking liquid, strained through muslin cloth or a fine sieve and mixed with additional water, milk, sugar and vanilla extract. The usual proportion is one cup of rice per two final litres of water. Variants: Oaxacan horchata incorporates blended red prickly pear and chopped nuts as a garnish; Yucatecan horchata carries grated coconut or coconut milk; coastal horchata replaces part of the water with evaporated milk for greater creaminess. Ground cinnamon sprinkled at serving is an almost obligatory decoration. Some families add peeled almonds soaked with the rice, evoking the original Arab recipe. The ideal texture is slightly thick but drinkable, with fine rice sediments that settle to the bottom of the glass.

Cultural significance

Horchata is one of the most recognisable drinks of Mexican popular cooking, a symbol of fondas, markets and family meals. It is served daily alongside jamaica and lime water in the classic trio of aguas frescas that defines the experience of eating in Mexico. It has a prominent presence at family celebrations, rural weddings, patron-saint fairs and Day of the Dead festivities. Traditional Mexican cuisine, UNESCO Intangible Cultural Heritage of Humanity since 2010, includes the aguas frescas as an everyday expression of its heritage. Oaxacan horchata, with its characteristic red prickly pear, is one of the icons of the Guelaguetza and of the state's regional festivities. In contemporary popular culture, Mexican horchata has crossed borders: in the United States it is part of the standard menu of any Mexican restaurant, and its consumption grows annually among Hispanics according to US food-industry data.

Frequently asked questions

What is the difference between Mexican and Spanish horchata?

Spanish Valencian horchata is made with tiger nut, a Mediterranean tuber; the Mexican one uses rice as a base. The Spanish one is richer and nutty-fruity; the Mexican one is lighter, sweeter and spiced with cinnamon. Both share an Arab-Mediterranean origin but evolved separately after the conquest. The tiger nut was not grown in America, which is why the New Spanish convents replaced it with rice.

What does Mexican horchata taste like?

It tastes of sweet rice with milk and cinnamon, with a vanilla background and a slightly grainy texture when home-made. It recalls drinkable rice pudding but lighter and more refreshing. Its mild, creamy and spiced profile makes it ideal for balancing the heat of salsas and stews. Served well chilled it is one of the most comforting aguas frescas of the Mexican repertoire.

What is the difference between Oaxacan and ordinary horchata?

Oaxacan horchata contains blended red prickly pear added at serving, creating a contrast of white and intense red colour, plus chopped nuts and finely cut melon. Ordinary Mexican horchata is white, without fruit, only with sprinkled ground cinnamon. The Oaxacan one is more festive and complex in flavour; both share the base of soaked and blended rice.

Does it necessarily contain milk?

It is not obligatory but very common. In the traditional rural version, the rice was soaked long enough for its natural starch to give the white creaminess, without the need to add dairy. Whole, evaporated or condensed milk was incorporated in the twentieth century to standardise and enrich the texture. There are vegan versions with almond or coconut milk that respect the original spirit.
