Can I use a different cut of steak for these tacos?
Yes. Skirt steak, carne asada, or sirloin work well. Avoid thick cuts; aim for thin, quick-cooking steaks that stay tender.
How do I know when the steak is cooked to the right doneness?
For medium-rare, grill 4–5 minutes per side for flank steak. Use a meat thermometer (130–135°F) or press-test: the meat should yield slightly to thumb pressure.
Can I make the avocado salsa ahead of time?
Make it up to 2 hours ahead. Store covered with plastic wrap pressed directly on the surface to prevent browning. Stir before serving.
What if I don't have tomatillos?
Use fresh green tomatoes or a 50/50 mix of regular tomatoes and lime juice for acidity. Green salsa will be less bright but still creamy and delicious.
How spicy are these tacos?
Heat level depends on jalapeño count and seeds. Remove seeds for mild; keep them for medium-hot. Adjust the number of jalapeños to your preference.
