When you add baking soda to melted sugar, a captivating reaction occurs. It turns a simple sugar mixture into something airy, light, and crispy. This process creates popular confections like honeycomb, Dalgona, and sea foam. By understanding why this happens, you can master not only candy-making but also enhance other culinary creations. This guide explores the science behind the reaction, its use in cooking, common questions, and solutions to typical problems.
The Science Behind Melting Sugar
Before discussing the reaction between baking soda and melted sugar, it’s important to understand how sugar behaves under heat. At 320°F (160°C), sugar melts and begins to caramelize. This transformation gives sugar its unique structure and rich flavor.
Caramelization Breakdown:
- Sugar molecules break down into simpler compounds, producing rich, complex flavors.
- The caramelization process turns sugar from clear to golden-brown syrup.
- This change adds bitter, nutty, and buttery flavors that enhance various dishes and sweets.
This process forms the base for many candies and sauces. To see how caramel can be used in a dessert, check out this Mini Key Lime Cheesecake recipe, which uses caramel drizzle to complement the tangy lime flavor.
What Happens When You Add Baking Soda to Melted Sugar?
The magic happens when you add baking soda to melted sugar. Chemically, baking soda (sodium bicarbonate) breaks down when heated. It releases carbon dioxide gas, which forms bubbles in the sugar mixture. These bubbles expand, creating a foamy texture. As the mixture cools, the bubbles remain trapped, resulting in an airy candy.
How Baking Soda Works:
- Heat causes baking soda to release carbon dioxide, water vapor, and sodium carbonate.
- The carbon dioxide bubbles form in the molten sugar and expand.
- As the sugar hardens, the bubbles stay trapped, giving the candy its porous structure.
Without baking soda, the sugar would harden into a solid block without any air pockets. You can learn more about how baking soda improves caramel in this guide on baking soda in caramel.
Why Does This Reaction Occur?
The reaction occurs because of baking soda and heat. Sodium bicarbonate decomposes when heated, turning into sodium carbonate, water vapor, and carbon dioxide gas. These carbon dioxide bubbles cause the sugar to expand and become light and crisp.
Here’s what happens:
- Baking soda breaks down at around 176°F (80°C), releasing carbon dioxide.
- The bubbles of carbon dioxide expand the molten sugar, creating a foamy texture.
- As the mixture cools, the bubbles remain trapped, producing the candy’s airy texture.
This reaction is similar to how baking soda causes baked goods to rise. However, in candy-making, the bubbles stay in the sugar as it cools, giving it a spongy texture. To explore more on how baking soda transforms caramel, check out Why Caramel Needs Baking Soda.
Popular Candies That Use Baking Soda and Sugar
Many confections rely on baking soda and melted sugar to achieve their distinctive textures. These candies are famous for their light, crispy texture and sweet, caramelized flavor.
Examples:
- Honeycomb Candy: Popular in the UK and Australia, honeycomb is made by mixing baking soda with melted sugar. The bubbles create a sponge-like structure, making the candy light and crispy.
- Dalgona Candy: Gained fame from “Squid Game,” this traditional South Korean candy forms when you add baking soda to melted sugar. The mixture foams, then solidifies into a crisp, light disc.
- Sea Foam Candy: Popular in the southern United States, this candy uses the same principles, with baking soda producing bubbles in the caramelized sugar.
If you enjoy working with caramel-based treats, you may also like making Homemade Caramel Chocolate Bars, where caramel and chocolate combine for a sweet, rich treat.
Other Uses for Baking Soda and Sugar in Cooking
Though baking soda and melted sugar are well-known in candy-making, they have other culinary uses. This reaction can enhance both sweet and savory dishes.
Other Applications:
- Caramel Sauces: Add a little baking soda to caramel sauces to stop crystallization and make the texture smoother. It neutralizes the caramel’s acidity, preventing the sugar from hardening too soon.
- Savory Dishes: In recipes with caramelized onions or brown sugar, baking soda can reduce bitterness and improve flavor. It can also make sauces foamier and lighter.

Common Questions About Baking Soda and Melted Sugar
Let’s address some frequently asked questions about working with baking soda and melted sugar.
FAQs:
- Why do you add baking soda to melted sugar?
Adding baking soda releases carbon dioxide, which forms bubbles that make the candy light and airy. - What happens if you don’t use baking soda?
Without baking soda, the sugar will harden into a dense mass without any air pockets or spongy texture. - Can you use too much baking soda?
Yes, too much baking soda can result in an unpleasant, soapy taste and a brittle texture. Stick to the recommended amount. - Does the sugar-baking soda reaction affect the flavor?
If you use the right amount of baking soda, it won’t affect the flavor. But too much can give the candy a bitter or soapy aftertaste.

Troubleshooting Common Issues
While adding baking soda to melted sugar is simple, it’s easy to run into problems. Here are some tips to help avoid common issues.
Problems and Solutions:
- Grainy Texture: If sugar crystallizes too soon, it can create a grainy texture. Make sure the sugar is fully melted and smooth before adding baking soda.
- Not Enough Bubbles: If your candy doesn’t foam enough, the sugar may not have been hot enough when you added the baking soda. Ensure the mixture is bubbling before you add it.
- Candy Sticking to the Pan: To prevent sticking, always line your baking tray with parchment paper before pouring the sugar mixture.
- Brittle Texture: If your candy turns out too brittle, you may have added too much baking soda. Use the recommended amount to ensure the right texture.

Conclusion: Mastering the Baking Soda and Sugar Reaction
In summary, adding baking soda to melted sugar is a simple technique that yields impressive results. It creates a range of popular candies like honeycomb, Dalgona, and sea foam by producing bubbles that lighten the texture of the sugar as it cools. Understanding this reaction can help you create these airy confections at home with ease.
Beyond candy-making, this technique has many applications in cooking, from caramel sauces to savory dishes. Mastering how baking soda interacts with sugar opens up endless culinary possibilities, allowing you to experiment with new textures and flavors.
