Getting to Know Baking Soda - A Versatile Pantry Staple

Baking soda, also known as sodium bicarbonate, is a familiar staple in many homes. But what exactly is this white powdery substance? How does it differ from baking powder? And what makes it such a versatile asset in cooking and home cleaning?

What is Baking Soda?

Baking soda, or sodium bicarbonate (NaHCO3), is a naturally occurring mineral compound. At room temperature it appears as an odorless, white crystal powder that dissolves quickly in water.

It has a wide range of culinary, health, beauty, cleaning and deodorizing applications. Its versatility comes from its unique chemical properties.

The Science Behind How it Works

When baking soda is combined with moisture and an acidic ingredient, an exciting chemical reaction occurs. The acid helps convert the bicarbonate (NaHCO3) into carbon dioxide (CO2) gas.

This release of gas is what enables baking soda to help batters rise and achieve a fluffy texture. It also explains why baking soda makes an effective deodorizer and cleaning agent across so many home uses.

Key Differences Between Baking Soda, Baking Powder and Bicarbonate of Soda

Baking soda is sometimes confused with a few related ingredients:

Baking Powder

While baking powder contains sodium bicarbonate/baking soda, it also includes the acidifying agents monocalcium phosphate and sodium acid pyrophosphate. This means extra added acidity to activate the sodium bicarbonate.

The baking powder does all the work of mixing moisture with an acid and base to prompt the release of CO2 bubbles. This eliminates reacting baking soda with additional acidic ingredients like lemon juice or vinegar in recipes.

Bicarbonate of Soda

Bicarbonate of soda is simply another term for baking soda or sodium bicarbonate. Baking soda and bicarbonate of soda are the exact same chemical compound. These names are used interchangeably depending on regional dialect and cuisine.

Helpful Substitutions and Equivalents

Handy conversions when you swap between baking soda, baking powder and bicarbonate of soda:

1 teaspoon baking powder = 1⁄4 teaspoon baking soda + 1⁄2 teaspoon cream of tartar
1 teaspoon baking soda = 1 teaspoon bicarbonate of soda

As a rule of thumb, triple the baking soda when substituting for baking powder (unless the recipe already includes an acidic ingredient).

How to Substitute

To substitute baking powder for baking soda:

1 tsp baking soda = 3 tsp baking powder

To substitute baking soda for baking powder:

1 tsp baking powder = 1⁄4 tsp baking soda + 1⁄2 tsp cream of tartar
1 tsp baking powder = 1⁄4 tsp baking soda + 5⁄8 tsp lemon juice or vinegar

Culinary Uses and Recipe Tips

From cookies to casseroles, breads to marinades, baking soda brings lightness, lift and enhanced browning to all kinds of home baked goods and cooking projects.

Enhances Browning and Crispness

The alkaline properties of baking soda increase the pH and speeds up the Maillard reaction responsible for that appetizing golden browning. Add a pinch to everything from fried chicken to grilled meats, breads and more.

Reacts with Ingredients Like Buttermilk

Many baking recipes already contain acidic ingredients like honey, chocolate, molasses or buttermilk. The built-in acidity reacts with baking soda, eliminating the need for added lemon juice or vinegar to activate rising.

Quick Breads and Batter Methods

When making scones, muffins, pancakes or other quick batters, gently mix in the baking soda just until combined to preserve the rising action. Overmixing once the baking soda is added deflates the air bubbles.

Neutralizes Refrigerator Odors

Place an open box of baking soda inside your fridge or freezer to absorb lingering food odors. Change the box every 30 days.

Health and Beauty Benefits

Beyond the kitchen, baking soda also offers an array of beauty, hygiene and health benefits thanks to its pH balancing and antibacterial properties.

Oral Health Support

Baking soda helps remove stains from teeth, freshens breath, and balances pH levels in the mouth. Mix a pinch with toothpaste or gargle with warm water and baking soda.

Soothes Heartburn and Indigestion

The alkaline profile of baking soda helps neutralize stomach acid and eases that burning feeling. Stir 1⁄2 teaspoon into water and drink slowly. Do not exceed 7 doses in 24 hours.

Exfoliates Skin and Boosts Shaves

Remove dead skin cells by mixing baking soda with a little water to form a paste for a soothing skin scrub. It also softens hair follicles for a closer shave when used on legs and more.

Deodorizes Shoes and Gym Bags

Sprinkle baking soda directly inside stinky shoes or fitness bags then allow to sit overnight before removing any powder residue. The bacteria combatting properties refresh even the foulest odors.

Tips for Storing Baking Soda

Follow these storage guidelines to help baking soda stay fresh and potent:

Keep it sealed at room temperature in a dark pantry
Store away from light, heat and moisture
Transfer used amounts to a separate container
Use clean, dry utensils each time

Replace every 2 years if used sparingly. Date the container to monitor freshness.

Look for Signs it's Expired

Clumping, yellow discoloration or loss of that distinctive sodium bicarbonate smell means it is past its prime. Expired baking soda won't make you sick, but loses its rising power and cleaning muscle.

Discover Endless Uses for Baking Soda

Humble baking soda packs a big punch across so many household applications thanks to its unique chemical properties and alkaline pH. Keep this inexpensive staple on hand to benefit cooking, cleaning, self-care routines and more!
