Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

2 cups sugar (450g)
¾ cup water (170ml)
¼ teaspoon cream of tartar
2 teaspoons lemon juice
A pinch of salt

Directions

1. Combine Ingredients:
In a heavy-bottomed saucepan over medium heat, add sugar, water, cream of tartar, lemon juice, and salt.

2. Dissolve Sugar:
Stir until the sugar is completely dissolved.

3. Simmer:
Once dissolved, lower the heat to medium-low and let the mixture simmer steadily. Stir occasionally to prevent scorching.

4. Reduce to Syrup:
Simmer for about 15–20 minutes, until the syrup thickens significantly. It should slowly drip off your spatula in a thick stream.

5. Test for Doneness:

• Drop a spoonful onto a cold plate and chill it for 10 minutes. If it becomes very thick and tacky, it’s ready.

• Or, use a candy thermometer and cook until it reaches 230°F (110°C).

6. Cool:
Remove from heat and place the pot in a bowl of cold water to cool it quickly. Let the syrup cool fully before using.

7. Store:
Once completely cool, transfer the syrup to an airtight container. You should have about 1⅓ cups (14oz/398g) of substitute syrup.

Servings and timing

Yield: Approximately 1⅓ cups (enough to replace store-bought corn syrup in most recipes)
Prep Time: 5 minutes
Cook Time: 15–20 minutes
Total Time: 25 minutes

Variations

• Citrus twist: Use lime or orange juice instead of lemon for a different flavor note

• Vanilla version: Add ¼ teaspoon vanilla extract after removing from heat for use in frostings and desserts

• Darker syrup: Use brown sugar in place of white for a more molasses-like flavor

• Thinner syrup: Simmer less if a thinner consistency is preferred

Storage/Reheating

Storage:
Store in a clean, airtight glass jar or container at room temperature for up to 3 months.

Reheating:
If the syrup thickens too much over time, warm it slightly in the microwave or in a pan over low heat until pourable.

FAQs

Can I use this as a 1:1 substitute for corn syrup?

Yes, this substitute is designed to replace corn syrup in a 1:1 ratio in most recipes.

Does this work for candy-making?

Yes, it works well in recipes that require the consistency and sweetness of corn syrup, but it may not prevent crystallization in high-precision candy like hard candy.

Is cream of tartar necessary?

Yes. It helps prevent the sugar from crystallizing and gives the syrup its smooth, glossy texture. Do not skip it.

Can I make this without lemon juice?

Lemon juice adds acidity to prevent crystallization and balance the sweetness. You can substitute with white vinegar if needed.

Is this gluten-free?

Yes, all the ingredients are naturally gluten-free.

Can I use brown sugar instead of white sugar?

Yes, but the result will be darker with a more caramel-like flavor.

Will this solidify when stored?

It may thicken slightly but should remain pourable at room temperature. If it solidifies, warm it gently before using.

Can I freeze this syrup?

Freezing is not recommended as it may alter the consistency. Room temperature storage is best.

Can I double or triple the recipe?

Yes, just scale the ingredients proportionally and use a larger pot to prevent boiling over.

Can I use this in marshmallow or pecan pie recipes?

Absolutely. It’s especially useful in homemade marshmallows, caramels, frostings, and pie fillings.
