Boiled Sugar Syrup

Introduction

You caramelize 2 cups of sugar until golden brown, then thin it with 5 cups of boiling water for a light caramel syrup. The final 3-minute cook smooths out the texture and finishes dissolving any hardened bits. You can use it as a make-ahead sweetener for drinks, desserts, or any recipe that needs a cooked syrup instead of dry sugar.

Recipe Details

• Prep Time: 5 minutes
• Cook Time: 15 minutes
• Total Time: 20 minutes
• Servings: 24

Ingredients

• 2 cups (480 g) granulated sugar
• 5 cups (1.2 L) boiling water

Instructions

1. Melt sugar in saucepan and heat slowly, stirring constantly until golden brown
2. Carefully stir in the boiling water.
3. Cook for 3 minutes, then remove from the heat.

Variations

• Replace 1/2 cup of the granulated sugar with light brown sugar if you want a darker color and a slight molasses note.
• Stop the sugar at a pale golden stage instead of a deeper amber if you want a lighter caramel flavor and less bitterness.
• Cook the syrup 1 to 2 minutes longer after adding the water if you want a slightly thicker final texture.
• Add a small pinch of salt after the water goes in if you want the sweetness to read a little sharper and more balanced.

Tips for Success

• Use a saucepan with high sides because the syrup can bubble up quickly when the boiling water is added.
• Keep the heat moderate while the sugar turns golden brown; once it starts coloring, it can go from amber to burnt fast.
• Make sure the water is fully boiling before you add it so the sugar is less likely to seize into hard clumps.
• If the syrup looks cloudy right after adding the water, keep cooking for the full 3 minutes; it usually clears as the sugar fully dissolves.
• Pull the pan off the heat as soon as the syrup is evenly golden and fluid, since residual heat keeps the caramel cooking.

Storage and Reheating

Pour the cooled syrup into a clean glass jar or other airtight container. Store it in the fridge for up to 1 month or freeze it in a freezer-safe container for up to 3 months, leaving some headspace for expansion.

To reheat, warm it gently on the stovetop over low heat or microwave it in short bursts, stirring between each one. If it thickens too much after chilling, stir in a small splash of hot water until it loosens.

FAQ

Why did the sugar harden when I added the water?

That can happen from the temperature change. Keep the water boiling, then continue cooking and stirring; the hardened sugar will dissolve again.

How do you know when the sugar is golden brown enough?

Look for a clear amber color, darker than honey but not deep brown. If it starts smelling sharp or smoky, it has gone too far.

Can you use brown sugar instead of granulated sugar?

You can replace part of the granulated sugar with brown sugar for a deeper flavor. Using all brown sugar will change both the flavor and the color more noticeably.

Can you make this ahead?

Yes. It is a good make-ahead syrup because it stores well and reheats easily if it firms up in the fridge.
