I have an older recipe that calls for 1 tsp. of carbonate of soda, and 3 teaspoons of bicarbonate of soda. I've never seen carbonate of soda in supermarkets. Is it available? Can you substitute bicarbonate of soda? Thanks.
These chicken fajitas get their flavor from a homemade marinade featuring dark Mexican beer, soy sauce, lime juice, oil, Worcestershire sauce, and garlic. They can be prepared on the stovetop with a grill pan as directed, or outside over a grill.
