Overview
- Observed on March 9, the celebration honors the tortilla de patatas and its many styles, with origins variously attributed to Cádiz or Navarra and other historical accounts.
- La Vanguardia marks the day with six recipes that range from the potato‑onion classic to zucchini with goat cheese and Padrón peppers, chorizo, chard, cod, and an open tortilla with chistorra and straw potatoes.
- Key technique from the guide includes roughly eight eggs per kilo of potatoes with one onion, low heat for a firmer set, or high heat for a runny center.
- Practical touches call for tender onion to soften the flavor and a pinch of guindilla in the Basque‑style cod tortilla popular in Euskadi’s cider houses.
- In Buenos Aires, venues such as El Casal de Cataluña and Pepito showcase their versions, advising very hot oil for frying potatoes and no more than five minutes in the pan for a babé texture.
