Chile Rellenos

1.Prepare the Poblano Peppers: Preheat your broiler to high or heat a heavy cast-iron skillet (or comal) over high heat. Place the poblano peppers directly under the broiler or on the hot skillet, turning every 3-5 minutes, until the skin is completely blackened and blistered on all sides. This process simulates stone-roasting.

2.Sweat and Peel the Peppers: Immediately transfer the hot peppers to a large bowl and cover tightly with plastic wrap, or place them in a sealed paper bag. Allow them to steam for 15-20 minutes. Once cool enough to handle, gently rub or peel the charred skin off the peppers. Make a vertical slit down one side of each pepper and carefully remove the seeds and veins, taking care to keep the pepper intact. Set aside.

3.Make the Tomato Sauce: While the peppers are steaming, place the halved tomatoes, onion, garlic, and jalapeño (if using) on a baking sheet and broil until slightly charred, about 5-7 minutes. Transfer the charred vegetables to a blender along with the chicken stock, oregano, and cumin. Blend until completely smooth.

4.Simmer the Sauce: Heat 1 tablespoon of vegetable oil in a medium saucepan over medium heat. Pour the blended sauce through a fine-mesh sieve into the saucepan (discarding any solids left in the sieve). Bring the sauce to a simmer and cook for 10-15 minutes, stirring occasionally, until slightly reduced and thickened. Season generously with salt and pepper. Keep warm.

5.Stuff the Peppers: In a small bowl, combine the Oaxaca and Monterey Jack cheeses. Gently stuff the cheese mixture into the cavity of each poblano pepper. If necessary, secure the slit closed using a toothpick.

6.Prepare the Batter: Place 1/4 cup of flour on a plate for dredging. In a large, clean bowl, beat the egg whites with the 1/2 teaspoon of salt using an electric mixer until stiff peaks form. In a separate small bowl, whisk the egg yolks with 2 tablespoons of flour until pale and slightly thickened. Gently fold the yolk mixture into the stiff egg whites until just combined, being careful not to deflate the batter.

7.Fry the Rellenos: Heat the 4 cups of vegetable oil in a deep, heavy-bottomed pot or Dutch oven to 175°C (350°F).

8.Batter and Cook: Dredge one stuffed pepper at a time lightly in the remaining 1/4 cup of flour, ensuring it is fully coated. Dip the floured pepper into the egg batter, turning to coat completely. Carefully lower the battered pepper into the hot oil.

9.Finish Frying: Fry the chile relleno for 3-4 minutes, turning once, until the batter is puffed, golden brown, and cooked through. Remove the pepper and place it on a wire rack or paper towel-lined plate to drain excess oil. Repeat with the remaining peppers.

10.Serve: Remove the toothpicks (if used) before serving. Ladle a generous pool of warm tomato sauce onto a plate and place one or two chile rellenos on top. Serve immediately.
