3-Step Execution Protocol

1
Preheat & Prep

Heat cast iron skillet over Low-medium — 300°F (149°C) surface, butter foaming but not browning until lightly smoking. Prepare fried eggs (sunny-side up) (2 large eggs cracked into a small ramekin first, then poured onto the pan).

2
Cook

Cook for 3–4 mins, undisturbed. Do not flip; allow surface to develop undisturbed.

3
Check & Rest

Whites are fully set with no translucent window near the yolk; yolks still tremble when the pan is nudged. Rest for 0 minutes before serving.

Verification Basis & Testing Rig

USDA FSIS egg-cookery guideline (cook until whites and yolks are firm, equivalent to ~160°F); FDA sanctioned pasteurized-in-shell egg carve-out for runny-yolk preparations served to at-risk populations.

Pro Tip: A well-seasoned cast-iron pan is the only home pan that will release a fried egg cleanly with butter alone — but only if it is preheated slowly. Crack eggs into a ramekin first so a shell fragment cannot drop straight into the pan. Sunny-side up leaves the yolk under 160°F, so if raw yolk risk is a concern (young kids, pregnancy, immune-compromised), use pasteurized-in-shell eggs or flip once for over-easy.
