Two ways to fry the things one with egg white one without.
When I make them I use the Masa Harina flour.
Any good batter will do fine.
Plus they dont have to be fried they can be baked without the breading on the outside.
The term rellano means stuffed in Spanish.
Chili rellano pablano is obvious but in Tex/Mex restaurants they do it with bell peppers too.
In my opinion disgusting.
This is kind of weird because a sweet pepper in Mexico is not called a chili it is I think called a pimento.
The large orange Aji Amarillo and Manzano makes a fine rellano.
One good way to eat the manzano is to cut up onion garlic and such mix with sardines stuff in manzano pepper and bake.
