Place your large skillet over medium-high heat. Let it get hot for about one minute—you should feel significant heat radiating from it when you hold your hand a few inches above the surface. Add the chorizo to the dry pan (no oil needed; chorizo releases its own fat as it cooks). This is important: you're not adding it all at once and stirring gently. You're breaking it apart with a wooden spoon or spatula as it hits the hot pan, encouraging it into small, bite-sized pieces. Here's what you're listening for: the chorizo should sizzle immediately when it hits the pan. If it doesn't, your pan isn't hot enough—wait another 30 seconds. As it cooks, you'll see it go from raw-looking reddish-brown to darker brown with crispy edges. The house will smell incredible—spiced, slightly smoky, deeply savory. This takes 7-8 minutes total. You want the chorizo broken into small pieces (no large chunks) and showing some browning on the edges, not still wet-looking. When it's done, transfer the cooked chorizo to a clean plate using a slotted spoon. This leaves behind all the delicious fat in the pan—don't drain it. That fat is liquid gold for cooking your vegetables.

Keep that same skillet on medium-high heat. Add the olive oil to the chorizo fat in the pan. Now add your diced potatoes, diced bell pepper, and diced onion. Stir everything together so the vegetables are coated in the oil and fat. Sprinkle the salt and pepper over top and stir again. Here's what happens next: the vegetables will make a sizzling sound. They'll release moisture and start to soften. Your job is to stir every two to three minutes rather than constantly fussing. This gives the potatoes a chance to actually brown on their edges instead of steaming themselves soft. You're looking for potatoes that are golden brown in places, tender inside when you poke them with a fork, and not mushy. The onion should be translucent and slightly caramelized at the edges. The pepper should be soft but still hold its shape. This takes 10-12 minutes total. In the last minute of cooking, add your minced garlic and stir constantly. Garlic burns quickly and turns bitter if you're not watching, so don't step away during this final minute. You'll know it's done when the garlic smells fragrant (not burned and acrid) and the potatoes are genuinely fork-tender. Transfer the cooked vegetables to the plate with the chorizo. Keep them separate for now—you'll be combining everything when you assemble the burritos.

While the vegetables are still cooking, grab your medium mixing bowl. Crack all 8 eggs directly into the bowl. Add the milk. Using a whisk or fork, beat the eggs and milk together vigorously for about 30 seconds. You want everything homogeneous—no streaks of white egg white, no separated yolks. The mixture should be pale yellow and uniform. This is the moment to notice: does it smell like raw eggs? Yes. That's completely normal and expected. Once cooked, it'll smell warm, buttery, and delicious.

Place your medium nonstick skillet over medium-low heat. Add the butter and let it melt completely, swirling it around to coat the entire pan. Once the butter is foamy and fragrant, pour in your egg mixture. This is critical: keep the heat at medium-low. Too high and your eggs cook too fast, becoming rubbery and dry. Too low and they'll take forever and get watery. Let the eggs sit undisturbed for about 30 seconds. You'll see them start to set around the edges. Using your spatula, gently push the set eggs toward the center of the pan and tilt the pan slightly so the uncooked egg flows to the edges. Repeat this motion every 20-30 seconds. This creates larger curds of egg rather than tiny, overworked scrambled pieces. Watch for the moment when most of the egg is set but still slightly glossy and wet-looking. This is the moment you pull the pan off the heat. The residual heat will continue cooking the eggs for another 10 seconds, and they'll finish perfectly creamy. If you wait until they look completely cooked in the pan, they'll be slightly overcooked by the time they get to your burrito. This takes 4-5 minutes total, and it's where the difference between creamy and rubbery eggs lives.

This might seem like a small step, but warm tortillas roll. Cold tortillas tear. Stack your six flour tortillas on a microwave-safe plate. Dampen a paper towel under cool running water (squeeze out the excess—you want it moist, not soaking wet). Lay the damp paper towel over the tortillas. Microwave on high for 30 seconds. Open the microwave and carefully touch a tortilla at the edge. It should be warm and flexible. If it's still a bit stiff, microwave for another 15 seconds. Keep the damp paper towel over the stack while you work so they stay warm. You've got about 5-7 minutes before they start cooling down, so work efficiently but not frantically.

Lay one warm tortilla flat on your work surface. Here's the filling ratio that works beautifully: imagine the tortilla divided into three vertical sections. You're going to fill only the bottom third of the tortilla—this is the most common mistake beginners make, and it's an easy one to catch and prevent. In this bottom third, layer in order: first, a handful of scrambled eggs (roughly ⅓ cup); then some of the chorizo and potato mixture (about ¼ cup); then a small pinch of shredded Cheddar (maybe 1 tablespoon); then 2-3 slices of avocado; then a tiny dollop of sour cream. Now the rolling: Fold the bottom edge of the tortilla up and over the filling, creating a tight cylinder. Don't roll loosely—you want it snug. Once you've rolled it once (and the filling is now wrapped), fold in the left and right sides of the tortilla, creating a envelope-like closure. Then continue rolling upward until the entire tortilla is wrapped around the filling. The burrito should be compact, with the seam facing down. Place it on a plate seam-side down—this helps it stay sealed and looks prettier. Repeat with the remaining five tortillas.

Serve the burritos immediately while they're warm. Alongside each burrito, offer small bowls or ramekins of salsa and sour cream for people to drizzle or dip as they like. The avocado inside keeps things creamy, but the extra sour cream and salsa add brightness and richness that make every bite more interesting. If you're making these ahead of time (more on that later), wrap each cooled burrito tightly in foil and store in the refrigerator. Reheat by unwrapping and microwaving for 60-90 seconds, or wrapping back in foil and warming in a 350°F oven for 15-20 minutes. The oven method keeps the tortilla from getting tough.
