Cemitas poblanas (Puebla sesame sandwich)

Ingredients

• 4 Cemita buns, sesame-seeded, enriched dough — not bolillo or standard roll
• 4 tbsp Chipotle chillies in adobo, mashed to a smear; not fresh jalapeño
• 2 Avocados, ripe, at room temperature, sliced
• 300 g Quesillo (Oaxacan string cheese), pulled by hand into ribbons, not sliced
• 1 small bunch Papalo (Porophyllum ruderale), leaves picked, raw and uncooked
• For the milanesa
• 600 g Pork loin or chicken breast, pounded thin for milanesa
• 120 g Plain breadcrumbs, for breading
• 2 Eggs, beaten, for breading
• 60 g Plain flour, for dredging
• 250 ml Neutral oil, for frying

Method

1. 1
   Pound the pork or chicken to an even, thin escalope. Dredge in flour, pass through beaten egg, then press firmly into breadcrumbs on both sides. The coating should be uniform with no bare patches — the eye confirms an even, pale crust.
2. 2
   Heat the oil in a wide pan over medium-high heat. Fry the breaded milanesa until deeply golden on each side and cooked through. The sound of active, steady sizzling — not violent spattering, not silence — marks the correct oil temperature. Drain on a rack.
3. 3
   Set a comal or dry griddle over medium heat. Place the cemita buns cut-face down and toast until the surface is just firm and lightly coloured. The touch of a fingertip should find resistance rather than give — the crumb has dried enough to resist sogginess.
4. 4
   This is where the sandwich lives or dies: spread a thin, even smear of mashed chipotle in adobo across the cut face of both halves. The quantity must be a smear — enough to coat the surface and perfume every bite with smoke and heat — not a pool that will flood the bread. The eye must see no bare patches and no excess.
5. 5
   Lay the avocado slices — room-temperature and ripe — across the chipotle base in an even layer. The avocado should yield to the lightest pressure: flesh soft but unbroken, not cold, not fibrous.
6. 6
   Distribute the pulled quesillo ribbons evenly over the avocado. The cheese should be in loose, overlapping strings — not compacted, not sliced — so that it settles into every cavity of the layers below. The sight of distributed ribbon, not a single slab, confirms correct technique.
7. 7
   Place the hot milanesa directly on the cheese. The residual heat will begin to soften the quesillo from below. The smell of warm sesame bread, smoke, and melting milky cheese rising from the open sandwich confirms the layers are properly assembled and at temperature.
8. 8
   Lay the raw papalo leaves over the meat. They are placed last and uncooked — heat destroys their pungent, citrus-bitter character. The nose should catch their sharp, green fragrance immediately on placement. Close the bun and press lightly. Serve at once.
