To boil quail eggs, you should place them in a pot of cold water, then bring the water to a boil. Once the water is boiling, reduce the heat to a gentle simmer and cook the eggs for 2 to 3 minutes. After this time, remove the eggs from the heat and place them in a bowl of ice water to cool them quickly and prevent further cooking.

The exact time may vary slightly depending on the size of the quail eggs and how well-cooked you prefer them. However, 2-3 minutes is a good general guideline for achieving a soft-boiled quail egg with a slightly runny yolk and a set white. If you prefer a firmer yolk, you can cook the eggs for a minute longer.
