The Egg (Gallus gallus domesticus)
Culinary Schools & Ratio Comparison
The egg-to-potato ratio defined by regional style and desired fluidity
Classic Tortilla
Balanced1 egg per 100 g raw potato. Uniform structure, stable juiciness, and clean sliceable texture.
Betanzos Style
Yolk Dominant12 eggs per 350 g potato. Highly fluid center with rich, unctuous yolk flow.
Competition Style
Extreme Creaminess12 eggs + extra yolks per 700 g potato. Exceptionally creamy texture with flawless thermal binding.
Beating Technique & Preparation
Mechanical and thermal factors determining the final texture
Gentle Mixing (No Foam)
Mix gently without aerating to prevent a spongy soufflé or cake-like texture.
Betanzos Method (Unbeaten)
Crack eggs directly over hot potatoes to start gentle pre-coagulation before hitting the pan.
The Resting Rule (3 to 5 min)
Rest the warm potato-egg mixture at 60 °C – 70 °C so gelatinized starch absorbs yolk and stabilizes emulsion.
