Horchata Flavor

Horchata is a family of sweet, milky-looking drinks made by soaking something starchy, blending it with water and straining it. The name probably comes from the Latin for barley, the original base. Which base you soak now decides what horchata tastes like, and two versions matter commercially.

Mexican horchata: rice and cinnamon

Agua de horchata is one of Mexico's aguas frescas, the sweet, cold drinks served alongside food. Long-grain white rice is soaked with cinnamon, blended, strained and sweetened. Many recipes add milk, evaporated or condensed milk, vanilla, or a few almonds.

It tastes of cinnamon first, then sugar, then a soft, slightly chalky cereal body from the rice. This is the horchata US taquerías serve, and it is what US shoppers expect when they see horchata on a coffee drink or an ice cream. Like taro milk tea, it is a flavor people know from a cup.

The cinnamon matters. Mexican cooks generally use canela, which is Ceylon cinnamon. It is softer, more floral and less hot than the cassia most US cinnamon products use.

Spanish horchata de chufa: tiger nuts

The older horchata, from Valencia, is made from tiger nuts (chufa). Despite the name they are not nuts but small tubers of a sedge, Cyperus esculentus. They are soaked, ground, pressed and sweetened. The drink is nutty and earthy, a little like a sweeter, earthier almond milk, with cinnamon or lemon peel as an optional extra.

Tiger nuts grown around Alboraya, just north of Valencia, carry the protected designation "Chufa de Valencia", and horchata made from them can carry the regulatory council's seal.

It is hard to sell far from home. Fresh tiger nut horchata spoils fast, and its starch thickens during pasteurization and then sets as it cools. So producers either skip heat treatment, which limits shelf life, or remove the starch, which takes some of the nutrition with it.¹

Central America has a third style, horchata de morro, made from ground jícaro (morro) seeds, often with rice and cocoa. It is a different profile again, which is one more reason to ask which horchata a brief means.

Building a horchata-type flavor

• Assume the Mexican profile in the US unless the brief says otherwise.
• Cinnamon, vanilla and a cereal note. A horchata-type flavor is built on cinnamaldehyde-led cinnamon and vanilla, plus a milky, cereal or toasted-rice note. The cereal note is what separates it from plain cinnamon-vanilla. Leave it out and people taste a cinnamon latte.
• Choose the cinnamon on purpose. Ceylon reads as authentic. Cassia is hotter and sharper and can tip into cinnamon candy. Cassia also carries far more coumarin, which the EU caps in several cinnamon-containing food categories. Check this if you sell there.
• Real rice or tiger nut brings body and trouble. Both starches thicken when heated and can set or separate as they cool. A ready-to-drink with real solids usually needs homogenization and a stabilizer, or enzyme treatment of the starch. See heat stability.
• Sugar is doing body work. Traditional horchata is sweet. Cut the sugar and you lose body as well as sweetness, the same problem covered in sugar reduction.
• Test in the real base. Cinnamon usually reads weaker in high-protein and high-fat bases than in water. A flavor tuned in oat milk will not behave the same in a whey shake.
