Tortilla Calculator
Estimate eggs, potatoes, onion, oil, and pan size for Spanish tortilla — then cook with olive oil discipline.
How this calculator thinks
Spanish tortilla is potatoes cooked gently in olive oil, bound with egg, and flipped. Ratios are starting points — wetter centers and firmer styles are house preference. Use enough oil to cook potatoes properly; do not starve the pan.
Gear that helps
A dedicated tortilla pan releases cleaner flips. Everyday EVOO is the cooking fat — see the tortilla pan buyer guide and olive oil which-bottle guide.
FAQ
Do I need onion?
Both styles are common in Spain. Pick one house rule and practice it — the calculator can include or omit onion weight.
Can I scale to twelve?
Yes in weight, but flip and thickness get harder. Two mid-size tortillas often beat one giant cake.
