I haven't thought this through very carefully, but it still seems to me that we should be able to establish a PelletFan Heat Rating so we can gauge published recipes.
It occurs to me that we can assign a numeric heat value to a commercial sauce, like Sriracha. Let's say we call it 8 on a scale of 10. We might assign Taco Bell Hot a value of 4 (it comes in three levels, Mild, Hot and Fire). Based on this information I can rightfully decide that a PF Heat Rating of 5 is my comfort limit.
We might select easily obtainable sauces and eat four drops on a soda cracker and decide that a given sauce is somewhat hotter than Taco Bell Hot but certainly not as hot as Sriracha and give it a PF Heat Rating of 6. Doing this a few times may produce a usable scale.
Of course I'm assuming that the heat in nationally sold sauces is consistent. AND, I'm assuming that there's interest in doing so. The dearth of posts may indicate that there's little interest.
