====== Chile Rellenos Batter (Capeado) ======

===== Ingredients =====
  * 4 large eggs, separated
  * ¼ tsp salt
  * 1 Tbsp all-purpose flour (optional but traditional)
  * 4 tsp cornstarch

===== Method (This Order Matters) =====
  - Whip whites to stiff but glossy peaks
  - Beat yolks with salt, flour, and cornstarch until smooth
  - Fold yolks into whites gently — stop while streaks still remain
  - Batter should mound briefly, then relax

  * If it flows like pancake batter → too loose
  * If it breaks → over-mixed
