Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Sugar Candy
Ingredients
Directions
The book gives no oven temperature. The 300°F in the steps was added when the recipe was transcribed, as a starting point.
Make the candy
In a saucepan, combine the sugar, water, vinegar, and cream of tartar.
Bring the mixture to a boil over medium heat, stirring until the sugar dissolves.
Continue boiling without stirring until it reaches the hard crack stage (300°F or 150°C).
Remove from heat and add vanilla extract to taste.
Set
Pour the mixture onto a greased surface to cool and harden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Forms the candy's sweet, glassy structure as it cooks and hardens.
- Cream of tartar
- Acid that helps prevent sugar from crystallizing, keeping the candy smooth.
- Vinegar
- Acid that helps keep the sugar from crystallizing, softening the final texture.
The step that matters
Boiling without stirring to hard crack stage. Stirring once the syrup boils can trigger sugar crystals that make the candy grainy. Reaching the correct temperature determines whether it sets hard and brittle.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, vinegar, cream):
- Vanillathe original
- Strawberryfits about as well
- Raspberryfits less well
- Pineapplefits less well
Fit is the average pairing score against sugar, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
