How do I know when the candy is done?

Use a candy thermometer — when the syrup reaches 300°F (149°C) , it’s ready. If you drop a small bit into cold water and it hardens instantly, you’ve hit the perfect hard crack stage .

Can I use cinnamon extract instead of oil?

No. Cinnamon extract isn’t strong enough and may evaporate under high heat. Always use cinnamon oil for authentic flavor and intensity.

Why did my candy turn sticky?

Sticky candy usually means it was undercooked or exposed to humidity. Make sure it reaches the correct temperature and store in an airtight container with a desiccant or light dusting of powdered sugar.

Can I make this without food coloring?

Yes! The food coloring is purely decorative. Without it, you’ll have a clear, glass-like candy with the same fiery flavor.

Ingredients

Scale

2 cups (400 g) granulated sugar
2/3 cup (160 ml) light corn syrup
3/4 cup (180 ml) water
1 teaspoon cinnamon oil (not extract)
Few drops of red food coloring (optional)
Powdered sugar, for dusting (optional)

Cook Mode Prevent your screen from going dark

Instructions

Line a baking sheet with parchment paper or a silicone mat. Measure out cinnamon oil and red food coloring so they’re ready to add quickly.
In a heavy-bottomed saucepan, combine sugar, corn syrup, and water. Stir over medium heat until the sugar dissolves completely.
Attach a candy thermometer to the pan and bring the mixture to a boil without stirring. Cook until it reaches 300°F (149°C), the hard crack stage.
Remove from heat immediately and let the bubbling settle for 10 seconds. Quickly stir in cinnamon oil and food coloring, being careful of strong fumes.
Pour the hot mixture onto the prepared baking sheet, tilting gently to spread evenly. Do not use utensils — the mixture will be extremely hot.
Allow the candy to cool completely for 30–45 minutes, then break into shards using the back of a spoon or knife handle.
Dust lightly with powdered sugar to prevent pieces from sticking together.
Store in airtight containers at room temperature for up to 3 weeks.

Notes

Use cinnamon oil, not extract — it withstands high temperatures and delivers stronger flavor.
Always use a candy thermometer to ensure the syrup reaches the hard crack stage (300°F).
Work quickly when adding flavoring and color — the syrup thickens fast.
Protect your hands with heatproof gloves; hot sugar can cause burns.
For flavor variations, try peppermint, cherry, or apple oil instead of cinnamon.
Store candy in a cool, dry place — humidity can make it sticky.
