I like seasonal products because you have to wait to the right time of the year, and when they arrive, they are much more appreciated. Furthermore, we link them to certain habits and ideas, so you are transported to that time of the year just by remembering them.
That happens to me with horchata. Its season is limited to summer, and that is why it is inseparable from the heat, the sun and the muggy weather.
And in Barcelona it is clear that drinking horchata is already a tradition, especially at a terrace. There are historical horchaterías, like "Tio Che" at La Rambla del Poble Nou, which this summer celebrated its Centennial! The founders were Joan and Josefa, who, coming from a village in the province of Alicante, began serving horchatas in the Born one century ago. And their family is still cooling the hot afternoons in Barcelona with this nutritious drink. Congratulations Tío Che!
