Boil Time Formula:
From: | To: |
The Hard Boiled Eggs Calculator helps determine the optimal boiling time for eggs based on their size and your cooking altitude. Proper boiling time ensures perfectly cooked eggs with fully set whites and creamy yolks.
The calculator uses the following formula:
Where:
Explanation: The formula accounts for both the egg size (which affects heat penetration) and altitude (which affects boiling point).
Details: Correct boiling time prevents undercooked eggs (with runny whites) or overcooked eggs (with greenish yolks and rubbery texture).
Tips: Select your egg size and enter your altitude in feet. For best results, use room temperature eggs and start timing when water reaches a full boil.
Q1: Why does altitude affect boiling time?
A: Higher altitudes have lower atmospheric pressure, which lowers water's boiling point and slows cooking.
Q2: What are the size classifications?
A: Small (under 53g), Medium (53-63g), Large (63-73g), Extra Large (over 73g).
Q3: Should I adjust for starting temperature?
A: This calculator assumes room temperature eggs. For refrigerated eggs, add 1-2 minutes.
Q4: How to prevent cracking?
A: Use a pin to prick the rounded end before boiling, and lower eggs gently into already boiling water.
Q5: What about soft-boiled eggs?
A: Reduce the calculated time by 2-4 minutes depending on desired yolk consistency.
