If you pour some boiling water into a cup and then put a long copper rod into the water, the other end of the rod becomes too hot to hold almost straight away - copper's ability to conduct heat is remarkable.

This idea then is for a normal stainless steel fork to have a copper core inside one of its tines ending in a small copper pad on the fork's handle where the end of your index finger would rest. This effectively then becomes a temperature probe, allowing you to quickly test the temperature of your food.

My understanding is that silver is even better at conducting heat than copper. Maybe you could exhume your trove of silver forks left from the days when people invited you to fancy parties and see how well the proposed application works.

Lead. Just shape your fork into a spoon when you need to, and easily conformable to your mouth structure...

Just stick your finger into your food.

//Just stick your finger into your food.// That's one of the arguments for eating with your fingers, which about a third of the world's population do. If it's too hot for your fingers, don't stick it in your mouth. (In general, eating with fingers may help to regulate what you eat, and how much; but that's another topic)
