There is no historical record of Miguel Hidalgo y Costilla having a documented favorite food. The "Father of Mexican Independence" (1753–1811) is remembered for his role in launching the 1810 insurgency with the Grito de Dolores, his parish priesthood in Dolores, and his progressive ideas on agriculture, industry, and indigenous rights—not for culinary preferences.
Popular culture sometimes attributes favorite foods to national heroes (e.g., Washington's cherries, Napoleon's chicken). For Hidalgo, no contemporary letters, diaries, or witness accounts mention a preferred dish. Any claim is speculative.
Hidalgo promoted agricultural diversification—encouraging vineyards, olive trees, mulberry for silk, and beekeeping—to reduce dependence on single crops and empower local economies. His legacy is economic vision, not a signature dish.
If you're celebrating Hidalgo (e.g., on September 16), serve regional Bajío fare: corn tortillas, frijoles charros, chiles rellenos, cajeta (goat milk caramel), and a glass of Mexican wine or pulque—foods he would have known and likely eaten.
