The meat and gravy inside a hot pie burn the tongue more easily than surrounding pastry even though all parts of are at same?

You're right, the meat and gravy inside a hot pie can burn your tongue more easily than the pastry, even though they're all at the same temperature. Here's why:

* Heat Transfer: The meat and gravy are denser and have a higher water content than the pastry. This means they transfer heat more effectively to your tongue. The pastry, being drier and less dense, will transfer heat slower.

* Surface Area: The meat and gravy likely come into direct contact with a larger surface area of your tongue, leading to a more intense heat sensation.

* Taste Buds: Taste buds are more sensitive to heat than the surface of your tongue. When you bite into a pie, the meat and gravy touch your taste buds directly, while the pastry might not.

In summary: Even though the pastry and filling are at the same temperature, the properties of the filling make it more likely to cause a burning sensation on your tongue.
