Why it works: Grape and pineapple match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 709 recipes. Both carry 1-hexanal, which smells fruit. The science ↓
Frosted Fruit
Ingredients
Directions
Frost the fruit
Heat the sugar on a paper near the fire or on the stove until hot but not melted.
Mix the egg white with cold water and beat until combined.
Dip the fruit in the egg mixture and shake off excess moisture.
Roll the fruit in the sugar until fully coated.
Place the coated fruit on a sieve near the fire to dry and harden.
Candy the pineapple
Prepare the pineapple by peeling and slicing it into ½ inch thick pieces.
In a preserving pan, boil sugar and water for 10 minutes.
Add the pineapple slices and boil for 15 minutes after it starts boiling.
Remove the fruit and place it on a sieve to dry for 30 minutes.
Continue boiling the sugar and water until thick or it hardens on a spoon dipped in cold water.
Dip the pineapple pieces in the thick syrup.
Place them to dry on a sieve or buttered plate, optionally dusting with fine sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the crisp, glassy coating on the fruit and sweetens it as it hardens.
- Egg white
- Acts as a binding glue so the sugar sticks evenly to the fruit.
- Pineapple
- Provides the main fruit that is candied in boiling syrup until glossy and firm.
The step that matters
Boil the syrup to the right thickness. Sugar syrup must be boiled long enough to reach the hard-crack stage, tested by dipping a spoon in cold water. Too little boiling leaves the syrup runny and the pineapple sticky; too much makes it brittle or burnt.
Swap the currant
How well each one fits the dish's main ingredients (grape, sugar, egg, pineapple):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against grape, sugar, egg, pineapple. Candidates are from the same food group and used in at least 100 recipes.
