Method
Place a dry cast iron skillet over medium heat. Toast the stemmed and seeded pasilla chiles for 30 to 60 seconds per side, using tongs to press them flat, until fragrant but not smoking.
Transfer the toasted chiles to a heatproof bowl and cover with the boiling water at 100°C/212°F. Submerge fully and let soak to rehydrate.
In the same cast iron skillet over medium-high heat, dry-roast the tomatillos, onion chunks, and unpeeled garlic cloves. Turn occasionally until all sides show dark, blackened blisters.
Remove the roasted vegetables from the skillet. Once cool enough to safely handle, peel and discard the papery skins from the garlic cloves.
Place the rehydrated pasilla chiles, 60ml of their soaking liquid, roasted tomatillos, roasted onion, peeled garlic, lime juice, and kosher salt into a blender. Blend until a smooth, cohesive salsa forms.
Halve the avocados, remove the pits, and slice the flesh into thick wedges.
Wipe the cast iron skillet clean and return to medium-high heat. Toast the corn tortillas one or two at a time for about 30 seconds per side until warmed through and flexible.
Divide the sliced avocado evenly across the warmed tortillas, laying the pieces in a line down the center of each.
Top the avocados generously with the blended pasilla tomatillo salsa. Garnish with the finely diced white onion and chopped cilantro. Serve immediately.
Chef's Notes
- Always toast dried chiles before rehydrating them. This brief exposure to heat awakens dormant essential oils and deepens their complex, earthy flavors.
- Retain the soaking liquid from the pasilla chiles. It contains a wealth of leached flavor, but always taste it first before adding it to the blender, as it can occasionally develop a harsh bitterness depending on the chile crop.
- To keep corn tortillas perfectly warm and pliable, immediately transfer them from the skillet into a slightly damp, clean kitchen towel. The trapped steam acts as a natural hydrator and prevents cracking.
- Do not assemble the tacos until the exact moment of serving. Warm tortillas paired with the cool, creamy room temperature avocado provide a delicate textural contrast that deteriorates rapidly.
