Stuff chile with cheese, roll together Once all are stuffed, place on plate / platter with wax paper as an underlayment and freeze until firm (1-2 hours)
Set up 3 casserole dishes: 1 buttermilk, 1 flour, 1 breadcrumb (in this order)
Dip a frozen relleno into buttermilk, then flour, back into buttermilk, then breadcrumb
Set carefully into pot of vegetable oil or fryer for about 2-3 minutes, until relleno floats
The use of wax paper is important so that the relleno doesn’t stick to the plates / platter in the freezer; once stuffed, freeze so that the relleno doesn’t fall apart while breading / frying.
Shredded chicken and diced onion can be stuffed with cheese also.
