Hello WeeknightCook_Midwest. Cooking salmon can indeed be a bit tricky because it transitions quickly from perfectly tender to dry if it stays on the heat for even a minute too long.
To ensure your salmon is safely cooked while remaining moist and flaky, the absolute most reliable method is to use a digital instant-read thermometer. Insert the probe into the very thickest part of the fillet. For salmon that is tender, juicy, and medium to medium-rare, you are looking for an internal temperature between 125 degrees Fahrenheit and 130 degrees Fahrenheit. If you prefer it fully opaque all the way through, you can take it up to 135 degrees, keeping in mind that the residual heat will continue to cook it slightly after you remove it from the heat source.
If you do not have a thermometer on hand, you can use the traditional fork test as a secondary method. Gently insert the tip of a fork into the thickest part of the flesh at an angle, then twist it slightly. The meat should easily separate along the natural flake lines and look opaque rather than translucent and shiny. If it resists or looks raw in the absolute center, give it another minute. I hope this helps you achieve a wonderful dinner tonight.
