To boil quail eggs, the cooking time varies depending on the desired doneness:

• For soft-boiled quail eggs with a runny yolk, boil for about 1.5 to 2 minutes.
• For medium-boiled quail eggs with semi-soft yolk, boil for about 2.5 to 3 minutes.
• For hard-boiled quail eggs with fully set yolk, boil for about 3 to 4 minutes.

After boiling, immediately place the eggs in an ice water bath to stop further cooking and make them easier to peel. It is recommended to bring the eggs to room temperature before boiling to prevent cracking.
