Substitute for Yeast in Baking
This is your emergency escape hatch. Baking soda is a base. Acid makes it fizz. Think vinegar, lemon juice, or buttermilk.
Mix them together, and boom—instant bubbles. No waiting. No proofing. It’s like a science fair volcano, but in your muffin tin.
Fun fact: If you use too much baking soda, your bread will taste like a metallic cave. Don’t ask how I know. Balance is key.
The Acid Lineup: Pick Your Fighter
Buttermilk is the cool, creamy judge. It gives a tender crumb and a subtle tang. Swap one cup of buttermilk for one cup of water in your recipe. Reduce the baking powder by a tad.
Lemon juice is the zesty comedian. It works fast. Very fast. Mix one teaspoon of lemon juice with half a teaspoon of baking soda to replace one teaspoon of yeast. Bake immediately. No dilly-dallying.
Yogurt is the silent star. Straight-up, plain yogurt works like buttermilk. Thicker, though. It adds moisture and a mild twang.
