There is no variety of green chile called Hatch. Hatch is a town in the Mesilla Valley about 90 minutes drive from where I live-lots of different varieties are grown there-Big Jim, Joe Parker, Sandia, etc. The problem is, the supermarkets call them Hatch Chiles.
The #1 green chile cheeseburger this year is at a place called Sparky's in Hatch.

Whenever my wife and I are driving back from Albuquerque, we stop at Sparky's.
