Replace Baking Powder with Baking Sodaに関する専門家の意見を丁寧に解説いたします。

If you swap in baking soda, you have to add something acidic to the recipe. The acid isn’t optional—it’s the key that unlocks the CO₂ prison. Common options: a tablespoon of lemon juice, white vinegar, or swap your regular milk for buttermilk.

Here’s a trick: if you’re using plain milk, stir in a teaspoon of lemon juice and let it sit for five minutes. You’ve just invented sour milk, which sounds gross but makes the fluffiest pancakes. Also, it’s a fantastic excuse to say “I’m creating a chemical reaction” when your roommate walks in.

When to Absolutely NOT Use This Hack

Don’t even think about doing this in recipes with no natural acid, like plain cookies or shortbread. You’ll end up with metallic-tasting discs of regret. The acid masks baking soda’s bitter, soapy flavor—if you skip it, your dessert will taste like a hand-washing demonstration.

Also, never use baking soda in a recipe that calls for a double-acting baking powder (most modern ones). Double-acting powder has two acid phases—one in the bowl, one in the oven. Soda only acts once, so your cake might rise beautifully, then faceplant. It’s a culinary tragedy.
