Baking Soda, Bicarbonate of Soda and Baking Powder are raising (leavening) agents which are added to your recipes to assist with the ‘rising’ process of your baked goods.
Baking Soda or Bicarbonate of Soda as it’s known in the UK is the pure form of sodium bicarbonate, and when combined with an acid, it produces bubbles of carbon dioxide. (If you have ever added bicarbonate of soda and white vinegar to clean your sink/drains then you’ll know about the bubbles and fizz I’m talking about).
If you add bicarbonate of soda to any ‘acid’ ingredient such as lemon juice, buttermilk, yoghurt etc. in your cake batter and then infuse heat from your oven, this will create a chemical reaction which allows your baking to rise.
Tip: Anything that...
