Every red chile begins as a green chile and then matures to red.
Most of the red varieties have thinner skin and minimal flesh compared to others. For example, the Hatch Red Hot Sandia Hot is very thin and ideal for drying and making red chile powder.
Other varieties like Hatch Red XHot Ms. Junie have thicker flesh. The thicker Ms. Junie pod will provide more flesh when roasted and peeled, but when drying it may need to be cut open and oven dried.
There are no solid rules for green chile – as both red chiles and green chiles are used fresh and dried for powder. In New Mexico there can be two or more harvests from the same chile plants. First the green chile harvest and then weeks later one or two red chile harvests. Green and red chile from the same plant may taste different and not have the same amount of heat. In our view all green chile is delicious, red or green.
