So now that it was brought up, is there any difference in heat or taste
between natural gas and propane?

The taste is produced by the fats and protein juices that drip down to the
high temperature element and then turn to smoke. Smoked meat has long been
a tasty bill of fare.

Consider charcoal ... which is often used to absorb odors (and hence taste)
.... charcoal grilling works the same way ... it's the smoke!
