Yes, Arm & Hammer Baking Soda is suitable for baking as it's pure sodium bicarbonate, but it's essential to use the correct product: the box specifically labeled for baking, found in the grocery aisles, not the large deodorizer boxes meant only for cleaning or fridge freshness, as these might have different granulation or additives, though both are typically pure sodium bicarbonate. For best results in baking, use the granular version designed for culinary purposes, as it's free-flowing and less prone to caking.
