Step 1

Position an oven rack directly underneath the broiler and preheat the broiler.

Step 2

In a small mixing bowl, combine the Mexican crema, hot sauce, lime zest and juice and salt to taste; stir to combine. Set aside to let the flavors meld together.

Step 3

Heat a large nonstick skillet over medium-high heat. Cook the chorizo and onions, stirring occasionally, until cooked through and slightly browned, about 5 minutes. Remove from the skillet with a slotted spoon to a paper towel-lined plate. Set aside until ready to stuff the roasted poblanos.

Step 4

Place the poblanos on a baking sheet and broil, turning once, until the skin is blistered and blackened, 4 to 5 minutes per side. Put the charred poblanos in a medium heatproof bowl, then cover with plastic wrap and let steam for 10 minutes. Peel and rub away the skins of the poblanos, then gently dry using a paper towel. Cut a 2-inch lengthwise slit in the center of each poblano and carefully cut out the seeds with kitchen shears, leaving the stems intact.

Step 5

Stuff each poblano with the chorizo and cheese, dividing evenly. Gently close the opening using 2 to 3 toothpicks to keep the filling from falling out.

Step 6

In a large skillet over medium-high heat, heat the oil until a deep-fry thermometer reaches 375 degrees F. Position a wire rack on a baking sheet.

Step 7

Meanwhile, add the egg whites to a large mixing bowl. Using an electric mixer, beat until medium peaks form. With the mixer on low, add the egg yolks and 1 tablespoon flour and mix until completely incorporated. The batter should be smooth and fluffy.

Step 8

Sprinkle the poblanos with salt, then dredge in the remaining 1/2 cup flour, tapping to shake off any excess; dip into the batter until fully coated. Gently add the poblano to the hot oil and fry in batches to not overcrowd the skillet. Cook until golden brown and crispy, 3 to 4 minutes per side. Transfer to the wire rack to drain. Serve warm on a platter and drizzle with the spicy lime crema and a side of yellow rice, if using.
