Notes on Making Chiles Rellenos
Chiles rellenos (literally, 'stuffed peppers') are super easy to make.  Here are a few general tips:
  • The chiles : The best chiles for rellenos are fresh poblanos and related varieties. If you can grow them, plant Poblano, Mulato Isleno, and Pasilla.  Let them ripen to red or brown (the poblanos in stores are almost always picked green).  Stuffed jalapeno peppers make an excellent (though sometimes spicy) appetizer.  If you must, you can get canned chiles already roasted and peeled.  But there is no comparison with using fresh chiles, especially fully ripe ones.

  •  
  • Roasting : You can roast the peppers over a charcoal grill or gas burner, but we generally spread them out on tin foil and roast them under the broiler.  Keep and eye on them, and turn them to toast them evenly all the way around.  It's ok if they get a little black - that's just the outer skin separating and burning - but be careful not to let them cook so much that the flesh dries out.  When a pepper has been toasted on all sides, drop it into a plastic bag (don't use the extremely thin bags, as they may melt). Keep the bag twisted shut. When all the peppers are in the bag, let it sit for 10 minutes or so to sweat.  (Alternately, wrap the roasted peppers in a damp towel.)

  •  
  • Peeling : Rinse each pepper under cold water and pull away the papery outer skin.  Don't worry if it all doesn't come off, but get as much of the loose skin as possible.  If the chile hasn't already split open, split it with a fingernail and remove all the seeds.  Try to keep the stem attached: it's a nice touch to serve the rellenos with the stem protruding at one end.  If a pepper shreds, save the pieces.  You can use them to patch other chiles as you fill them.  (If your skin is sensitive to the oils in the peppers, try rinsing your hands in lemon juice while handling them.)

  •  
  • The seeds : You can save the seeds from the chiles and make an excellent condiment out of them.  Toast them in a dry skillet or in the oven until they start to brown, then grind them together with dried peppercorns (in approximately a 2:1 ratio of seeds to pepper).  Store this spice in a sealed jar and use it to flavor relleno fillings, soups, and other Mexican dishes.

  •  
  • Stuffing : Though most chiles rellenos you find in Mexican restaurants are stuffed with cheese, there are endless possibilities.  They are easier to stuff if the filling has enough of a binder (cheese, egg, rice) to hold together when squeezed into a ball, but even that is not a requirement.  It's easiest to stuff all the chiles at once and place them on a plate to hold them for the next step.  You can use a little bit of flour to bind the overlapped edges.  If a pepper falls apart as you are stuffing it, do the best you can to squeeze the stuffing into a chile-shaped ball inside strips of chile.  The batter will help the whole thing hold together.

  •  
  • Batter : There are lots of ways to coat and fry chiles rellenos.  Here is our favorite, which happens to be very easy and requires almost no grease:  Separate eggs (you'll need 1 egg to coat 2-3 rellenos), add a pinch of salt to the whites, and beat them until completely stiff.  Sprinkle a few tablespoons of flour over them.  Add a teaspoon of water to the yolks, beat them briefly, then fold them into the whites in a few strokes.  That's all there is to it.  Dip each relleno into the batter and place it on a lightly greased hot griddle or pan.  You don't have to be careful about coating the rellenos evenly.  When you've dipped them all, you can carefully pour the extra batter over the frying chiles.

  •  
  • Frying : Cook the rellenos on one side until the batter on the bottom has turned golden brown.  Carefully flip them over.  It often works best to cook them on three sides, to get all the batter to cook evenly.  Serve them immediately or keep them warm on a plate in the oven until you are ready to serve.  Check out our recipes for serving suggestions and sauces.
