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 ↓
Carrots
Ingredients
Directions
Prepare and boil
Boil a saucepan of water.
Add 2 tablespoons of coarse sea salt when the water is boiling.
Add young carrots to the boiling water and cook for 20 minutes.
Check tenderness with a fork; they should be tender all through.
Boil for 30 to 45 minutes if they are older.
Remove the carrots and rub them clean with a cloth.
If older, wash, scrape, and cut them to resemble young carrots before boiling.
Glaze and serve
Place boiled carrots in a stewpan.
Cover with good stock.
Add a piece of butter the size of a nut and sprinkle with 2 teaspoons of caster sugar.
Boil in the stewpan until reduced to a glaze over the carrots.
Remove from the stewpan and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- The main vegetable; boiling softens them until they are tender all through.
- Good stock
- Liquid that reduces into a savoury glaze that coats the carrots.
- Caster sugar
- Adds sweetness and helps the reduced liquid turn into a glossy glaze.
- Butter
- Adds fat and richness, giving the glaze a smooth, glossy finish.
The step that matters
Reducing the stock to a glaze. As the liquid evaporates, the sugar and butter concentrate into a glossy coating. Boiling too long can scorch the sugar and dry the carrots, so watch the pan closely.
