Why it works: Sugar and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Orange Straws
Ingredients
Directions
Prepare
Cut orange skins into strips.
Boil the strips, changing the water 3 times, until tender and no longer bitter.
Make the candy
Make a syrup with equal parts sugar and water.
Cook the peel in the syrup for 10 minutes.
Lift the peel out with a fork or skimmer and place on a plate.
Coat and set
When cool, roll the peel in granulated sugar.
Place on a buttered plate.
Roll again in sugar the next day.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Orange and sugar barely smell alike, yet cooks put them together in 19,212 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
- Orange skins
- Provide the candy's main body, citrus aroma, and a chewy texture once cooked.
- Sugar
- Sweetens the peel and, as the syrup thickens, helps it turn firm and glossy.
- Water
- Dissolves the sugar into syrup and carries away bitter compounds during boiling.
- Granulated sugar
- Forms a dry sweet coating that keeps the pieces from sticking together.
The step that matters
Boiling the strips until no longer bitter. The bitter compounds in the white pith leach out slowly into the water. Changing the water and boiling until the strips are tender removes most of this bitterness, so the candy tastes sweet and citrusy rather than harsh.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter):
- Vanillafits better
- Figfits better
- Peachfits better
- Orangethe original
Fit is the average pairing score against sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
