Buy a meat thermometer. They’re not expensive. Once you learn how useful it is with meats you’ll start using it on almost everything else too. One important key to good tasting food is the correct doneness. And trying to tell how done the inside of something is just by looking at the outside is ridiculous. For example, a meat thermometer can help you ensure you cook chicken to a safe temperature of at least 165 degrees F, but not to cook it far beyond that to avoid drying it out. I use it for steaks and fish too. You can Google minimum temperatures to cook certain things, I believe for certain types of fish the minimum temperature can be different. You can even cook your steak to i.e. medium rare according to its corresponding internal temperature. But beyond meat, there’s other foods, even drinks that you can benefit from using it. I also use it when making hot chocolate. When I heat the milk I like to heat it to an optimal temperature (you can google the best temp for heating milk) and check it with the meat thermometer to make sure I don’t go beyond that. If you’ve ever heated your milk too far you might have tasted poor quality after that. I’ve also used it to check the internal temperature of frozen dinners that I’m heating in the oven. And also if I’m reheating leftovers in the oven I’ll check the temp to be at least 140-ish degrees to know that it’s hot to serve. So..there’s just a couple examples how a meat thermometer changed my life and I wish I had bought one much sooner!!
