Beer Marinated Carne Asada Tacos

INGREDIENTS

• 1.5kg/3pound flank steak
• 1 bottle Mexican beer
• 1 bunch cilantro/coriander (use the root for the marinade and the leaves to finish or for salsa)
• 2 large navel oranges, juiced
• 3 garlic cloves, minced/finely sliced
• 2 teaspoons ground cumin
• 1 tsp mild-medium chile powder (ancho, chipotle, etc, if using cayenne, use a smaller amount)
• 2 tablespoons vegetable oil
• salt & pepper

INSTRUCTIONS

1. Rub dry ingredients over flank steak and put into a bowl/container
2. Add in all wet ingredients, cover and put in fridge to marinade from 1-4 hours.
3. Don't leave it longer than this - the beer and fruit juice acid will break down the flesh too much.
4. Remove steak from fridge a half hour or so before cooking.
5. Heat a grill (preferably charcoal) to searing hot.
6. Place steak on grill, brushing off any chunks of garlic or coriander root.
7. Cook flank steak approx 8 minutes each side. 
8. Rest under foil for 10 minutes before slicing and serving.
