Rusa de Tonicol Sinaloense

This is from Sinaloa. From the Pacific coast, from the puestos along the Malecon de Mazatlan, from the abarroterias of Culiacan and Los Mochis where the Tonicol bottles sit in metal tubs of ice next to the door. La Rusa is the drink of a hot Sinaloan afternoon and it is built around one bottle that does not exist anywhere else: Tonicol, the vanilla soda made in El Rosario, Sinaloa, since 1947.

There is no substitute for Tonicol. People have tried. Cream soda is too sweet and tastes like cake. Vanilla Coke is wrong from the first sip. The Tonicol vanilla is softer, almost milky, with a faint salinity that the people of El Rosario will tell you comes from the well water they bottle it with. That vanilla is the spine of the drink. Remove it and you have orangeade with a chile rim. No me vengas con atajos.

The rest is honest northwest Mexico. Fresh orange juice, fresh lime, a real pinch of salt, a chamoy-Tajin rim sticky enough to leave fingerprints on the glass, a tamarindo pulparindo straw pushed down into the ice so every sip pulls a little sweet-sour-salt up through the soda. This is not a cocktail. It does not need to be. In Sinaloa, you give the Rusa to the kids at a quinceanera, to the tia who does not drink, to the man who is driving home after the carne asada. It is a mocktail because it was always a mocktail. The desert pours into the glass and you do not need anything else.

My mother never made a Rusa. She was from Jalisco and Jaliscienses drink tejuino. But I learned this drink in 2009 from a senora running a puesto outside the Mercado Pino Suarez in Mazatlan, who told me, mija, the secret is the salt, and the Tonicol must be cold enough to hurt your teeth. Cada estado, su propia cocina, and Sinaloa pours its sun and its sea and its sweet vanilla soda into a single tall glass.
