You can make a big batch. Save time. Look like a domestic god.
Store it in an airtight container. A mason jar works. A ziplock bag works too. Just squeeze out the air.
Keep it in a cool, dark place. Light and heat are the enemies. They kill your baking powder’s mojo. Label it so you don’t grab it for cookies and make salty biscuits.
How Long Does It Last?
About three months. After that, the baking powder starts to yawn and fall asleep.
Test it if you’re unsure. Drop a teaspoon of your mix into a cup of hot water. If it fizzes happily, you’re golden. If it sits there like a dead fish, make a new batch.
Freshness matters, folks. Your pancakes deserve a fighting chance.
