• 1 Jalapeño (seeded and finely diced; optional for heat)
• 2 tablespoons Fresh Cilantro (chopped, divided between marinade and garnish)

Instructions

1. Make the Marinade

   In a small mixing bowl whisk together 1/4 cup olive oil, 2 tablespoons fresh lime juice, 1 tablespoon chili powder, and a pinch of salt and black pepper until well combined.

   Time: PT5M

2. Marinate the Fish

   Place the flounder fillets in a shallow dish, pour the marinade over them, then sprinkle the diced jalapeño and 1 tablespoon chopped cilantro on top. Cover and refrigerate for 15–20 minutes; do not exceed 20 minutes or the acid will start to “cook” the fish.

   Time: PT17M

3. Prepare the Cabbage Slaw

   In a large mixing bowl combine 2 cups shredded cabbage with 1 tablespoon red wine vinegar, a pinch of salt and black pepper. Toss to coat evenly.

   Time: PT5M

4. Prep Toppings

   Thinly slice 1/4 cup red onion, dice the tomato, chop the remaining cilantro, and dice the avocado (if using). Set aside.

   Time: PT5M

5. Cook the Fish

   Heat the skillet over medium‑high heat. Add the marinated fish and cook 3–4 minutes on the first side, then flip and cook another 2–3 minutes until the fish flakes easily with a fork.

   Time: PT7M

   Temperature: medium-high heat

6. Warm the Tortillas

   Place the tortillas in the same skillet (or a separate dry pan) over medium heat for about 30 seconds per side, just until pliable and lightly toasted.

   Time: PT2M

   Temperature: medium heat

7. Assemble the Tacos

   Lay a warm tortilla on a plate, add a portion of cooked fish, top with cabbage slaw, red onion, tomato, avocado (or guacamole), and a sprinkle of fresh cilantro. Finish with a squeeze of lime juice.

   Time: PT5M

• Whisk
• Shallow Dish
• Skillet
• Tongs or Spatula
• Cutting Board
• Chef’s Knife
• Large Mixing Bowl
• Measuring Spoons
• Plate for Serving

Critical Steps — Do Not Skip

• Do not marinate the fish longer than 20 minutes, or the lime acid will make it mushy.
• Cook the fish just until it flakes; overcooking dries it out.
• Warm the tortillas briefly to keep them pliable and prevent tearing.

Chef Tips from the Video

• For extra flavor, add a pinch of smoked paprika to the marinade.
• A drizzle of crema or sour cream mixed with lime zest elevates the taco.
• If you like extra crunch, toast the shredded cabbage lightly before mixing with vinegar.

Troubleshooting

Storage

Refrigerator: Store cooked fish, slaw, and toppings in airtight containers for up to 2 days. Reheat fish gently before serving.

Freezer: Raw marinated fish can be frozen for up to 1 month; thaw in the refrigerator before cooking.

Room temperature: Assembled tacos are best eaten immediately; do not leave at room temperature for more than 1 hour.

Make-Ahead Tips

• Marinate the fish up to 30 minutes ahead; keep refrigerated.
• Prepare the cabbage slaw and store in the fridge; it stays crisp for several hours.
• Slice onions, dice tomato, and chop cilantro up to 2 hours before serving; cover with plastic wrap.
