Preheat the grill to high heat (204°C). Place a cast iron skillet on the grill two minutes before cooking to preheat.

Add chopped bacon to the hot skillet. Cook over medium heat, stirring occasionally, until crispy, about 8–10 minutes. Remove bacon with a slotted spoon and reserve the rendered fat. Let the fat cool.

Crumble the cooled, crispy bacon. In a medium bowl, combine 120 ml (1/2 cup) cooled bacon fat (top up with canola oil if needed), egg yolks, Dijon mustard, lemon juice, and white vinegar. Use an immersion blender to emulsify until thickened and pale. Gently fold in the reserved bacon and chopped chives to finish the baconnaise.

Brush grill grates lightly with oil. Grill chorizo sausages for 10–15 minutes, turning halfway, until cooked through and an internal temperature of 74°C is reached. Rest sausages briefly.

Return the skillet to medium heat. Add jalapeño and red onion. Sauté for 5–6 minutes until softened and lightly caramelized.

Add a small amount of oil to the same skillet. Add shredded jack cheese; stir constantly over low heat until fully melted and gooey. Remove from heat immediately.

Place hot dog buns on plates. Spread each with baconnaise, add a grilled chorizo sausage, spoon over melted cheese, and top with sautéed jalapeño and red onion. Serve at once.
