What is the general guideline for boiling fish, and how does it vary by type?
The general guideline for boiling fish is to cook it for 8-12 minutes per inch of thickness. However, this time may vary depending on the type of fish, its density, and personal preference for doneness. For example, delicate fish like sole or flounder may require shorter cooking times, while thicker fish like salmon or cod may need longer times.
It’s also important to note that some fish, like trout or tilapia, may have a higher moisture content, which can affect cooking time. In these cases, it’s best to check for doneness by inserting a fork or knife into the thickest part of the fish. If it flakes easily, it’s cooked through. If not, continue to boil in 1-2 minute increments until it reaches the desired level of doneness.
How do I determine the thickness of the fish to calculate boiling time?
To determine the thickness of the fish, measure it at its thickest point, usually near the spine. You can use a ruler or calipers to get an accurate measurement. Make sure to measure the fish after it has been cleaned and scaled, as these processes can affect its thickness.
