Take a baking sheet and line it with aluminum foil.
Put the chile peppers on the sheet.
Now, cook it in the oven's preheated broiler for 10 minutes. Let them turn black on both sides and be blistered.
Take a bowl and put the blackened peppers into it.
Seal the bowl with plastic wrap.
Meanwhile, as the peppers begin to cool, let them steam for about 10-15 minutes.
Use cold water for peeling off the skins of cooled peppers.
Pertinently, take off the seeds and core from each of the pepper.
Wash the peppers inside out and let them dry.
Add cheese strips to the peppers.
Take a bowl. Mix baking powder with the egg yolks.
Take another bowl. Blend the egg whites in an electric mixer. Ensure that have formed stiff peaks.
Next, this beaten egg whites mixture has to be folded onto the prepared yolk mixture.
Now, take a shallow bowl for flour.
Take a skillet. Heat vegetable shortening over medium heat.
Each stuffed pepper has to be rolled in the flour with tapping off excess flour and dipped into the mixture of eggs. Ensure both the sides are properly coated.
Next, place them into the skillet.
Let the peppers fry so that they get golden brown and the cheese gets melted. It would take about 5 minutes to fry both sides of the coated peppers.
