Tip: Use a Thermometer to Grill Meat to Perfection
Patrick Norton of tekthing.com has a tip for better grilling. Instead of trying to feel it out with your fingers how done meat is, buy a thermometer. Patrick recommends the Lavatools thermometer, which can be found on Amazon for around $25.
If you want to get your meat done a certain way, there's a temperature for that, and having a thermometer will ensure that it's done the way you want. It will also prevent you from getting some food related illness from not cooking something enough.
