Question: is baking powder and bicarbonate of soda the same uk?
Answer: As far as the UK goes, the difference is that Baking Powder is Bicarbonate of Soda PLUS cream of tartar which acts as a raising agent in baking. ... In the UK, you may well see Arm & Hammer Baking Soda on shelves - that is what we'd refer to as Bicarbonate of Soda.
