Throwing all the grated cheese into a pot at once guarantees a clumpy, separated mess of dairy solids and pools of oil. Fondue originates from the Alpine regions of Switzerland and France, developed as a practical method to utilize hardened cheese and stale bread during cold winters. Achieving a smooth texture requires understanding how starches and acids interact with dairy proteins.
Tossing the grated cheese with cornstarch before melting is the single technique that determines success or failure. Starch coats the cheese proteins, preventing them from binding tightly together into a solid mass when heated. Furthermore, the acid in the wine or beer lowers the pH of the mixture, which keeps the proteins relaxed and dispersed in the liquid. Add the cheese gradually by the handful over medium-low heat, stirring constantly in a figure-eight motion until each addition is fully incorporated before introducing the next.
