MAKE THE FILLING THE POINT

Whether you are shredding king oyster mushrooms, pulsing toasted walnuts with guajillo chilli, or searing skirt steak over cast iron, a taco filling needs two textures in the same pan: tender interior bite and caramelized, crispy edges.

BUILD YOUR NEXT TACO

1. CRISPY OYSTER MUSHROOM & CACAO NIB CARNITAS

Why it belongs: Oyster mushrooms have long chitin fibres that shred like braised pork shoulder and absorb citrus-fat emulsions without falling apart.

Pan / Oven220°C Sheet Pan + Skillet
Batch Yield8 Generous Tacos (480 g)

Ingredients & Ratios

  • 600 g king oyster and pearl oyster mushrooms, hand-torn into 6 mm strips
  • 45 ml neutral high-heat sunflower or avocado oil
  • 60 ml fresh squeezed navel orange juice
  • 15 ml soy sauce or tamari (for glutamate depth)
  • 1 tbsp roasted cacao nibs, finely crushed in a mortar
  • 1 tsp ground cumin, 1 tsp smoked paprika, 1/2 tsp cinnamon
  • 3 cloves garlic, microplaned, plus 1 bay leaf

Step-by-Step Execution

  1. Dry Shred: Never wash oyster mushrooms under running water; brush off debris and pull stems apart lengthwise with two forks to create ragged surface area.
  2. Roast for Evaporation: Toss strips with oil, salt and spices on a wide rimmed baking sheet. Roast at 220°C for 18 minutes until free water evaporates and tips turn dark amber.
  3. Glaze & Crisp: Transfer roasted mushrooms to a hot cast-iron skillet over medium-high heat. Pour in orange juice, soy sauce, garlic and crushed cacao nibs. Toss for 4 minutes until the liquid reduces into a sticky, crackling crust.

Pair with: Blistered Tomatillo & Pistachio Verde to cut the earthy cacao notes.

2. CHARRED CHORIZO-SPICED WALNUT & SWEET POTATO HASH

Why it belongs: Walnuts contain natural polyunsaturated oils that toast like pork fat when coated in vinegar and dried chillies, while sweet potato cubes provide creamy starch contrast.

Component Breakdown

  • 200 g raw walnut halves, toasted 6 minutes at 180°C
  • 150 g firm brown lentils, cooked and thoroughly drained
  • 400 g orange-fleshed sweet potato, peeled and cut into 1 cm cubes
  • 2 tbsp guajillo chilli powder + 1 tbsp ancho chilli powder
  • 25 ml apple cider vinegar (signature chorizo tang)
  • 1 tsp dried Mexican oregano, 1/2 tsp ground cloves, 1 tsp kosher salt

Pan Sequence

  1. Pulse Coarsely: Pulse toasted walnuts, drained lentils, chilli powders, vinegar and spices in a food processor using six 1-second bursts. Stop while pebbly—never blend into butter.
  2. Blister the Sweet Potato: Sear 1 cm sweet potato cubes in 2 tbsp oil in a wide skillet for 10 minutes, turning only every 3 minutes so flat faces caramelize.
  3. Combine & Toast: Push potatoes to the perimeter, add the walnut-lentil chorizo mixture to the centre hotspot, and let it crisp undisturbed for 4 minutes before tossing together.

Pair with: Fresh Pressed White Corn Tortillas and pickled white onions.

3. COFFEE-ANCHO RUBBED SKIRT STEAK & CRISPY HALLOUMI AL PASTOR

Two high-protein options—one carnivorous, one vegetarian—built around Maillard crusting and bright acid balance.

Coffee-Ancho Rubbed Skirt Steak

Outer skirt steak has coarse muscle grain that drinks up dry rubs and chars in under 4 minutes per side. Combine 1 tbsp finely ground dark roast coffee, 1 tbsp ancho powder, 1 tsp dark muscovado sugar, 1.5 tsp flaky salt and 1 tsp garlic powder. Pat 500 g skirt steak bone-dry, coat evenly, and rest 20 minutes at room temperature.

Sear in a smoking-hot cast-iron pan for 3 minutes per side for medium-rare (54°C internal). Rest 8 minutes on a warm board, cut into 7 cm lengths with the grain, then slice 6 mm strips strictly perpendicular to the muscle fibres so every bite yields effortlessly.

Seared Halloumi & Charred Pineapple Al Pastor

For a vegetarian filling that holds its chew at high heat, cut 450 g block halloumi into 8 mm slabs. Whisk a marinade of 2 tbsp achiote (annatto) paste dissolved in 60 ml pineapple juice, 15 ml cider vinegar, 1 minced chipotle in adobo and 1/2 tsp cumin.

Sear fresh pineapple spears in a dry skillet until blackened streaks appear, dice fine, then sear the achiote-painted halloumi slabs for 90 seconds per side until a lacy golden crust forms. Chop into bite-sized batons and toss with the charred pineapple right before loading your tortillas.
