Notes
⭐️ Top Tip
Ensure Your Baking Powder Is Fresh: If the baking powder is past its use-by date, your cakes and muffins won't rise properly. To check if it's still active, try this quick test:
Boil some water.
Place ½ a teaspoon of baking powder into a small ramekin or mug.
Pour in about 100ml of the hot water.
If it fizzes and bubbles energetically, it's active, if it does nothing or fizzes weakly, it's time to replace it.
