Make the Carnitas
Season pork with salt, pepper, cumin, and oregano.
Add pork, onion, garlic, bay leaf, and enough water to cover to a large pot.
Simmer 1.5–2 hours, until tender.
Shred and — if you want that street-cart texture — crisp the pork in its own fat in a hot pan.
Make the Spicy Salsa Roja
Toast árbol chiles for 1 minute (don’t burn).
Boil chiles + tomatoes 5–7 minutes.
Blend with garlic, cumin, oregano, vinegar, salt, and a splash of cooking water.
The result should be punchy, deep red, and unapologetically hot.
Make the Mild Tomato Sauce (Optional)
Blend boiled tomatoes, onion, garlic, and salt until smooth.
This lets you layer heat for mixed spice levels.
Build the Torta Ahogada
Slice roll lengthwise (not all the way through).
Stuff generously with carnitas.
Toast lightly if you want extra crunch (recommended).
Pour mild tomato sauce first (optional).
Drown with the spicy chile sauce until you can barely see the bread.
