Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Sponge Taffy
Ingredients
Directions
Cook the sugar
Boil glucose and sugar over low heat until it reaches the 'ball' stage, stirring constantly with a wooden paddle.
Add flavoring to taste.
Whisk the egg whites to stiff peaks and fold them into the mixture.
Continue stirring and evaporating until the mixture does not stick to the back of your hand.
Shape and set
Pour or scrape the mixture onto an oiled slab between iron bars.
Oil your hands slightly and flatten the mass to the desired thickness.
Let it rest until firm enough to cut into squares or cubes, then wrap in waxed paper.

What each ingredient does
- Glucose
- Keeps the candy soft and chewy by limiting sugar crystallization.
- Sugar
- Provides sweetness and the bulk structure of the candy once cooled.
- Egg whites
- Whipped into foam, they create the light, airy sponge texture.
The step that matters
Continue stirring and evaporating until the mixture does not stick to the back of your hand. Cooking off enough water sets the final texture. Too little cooking leaves the taffy sticky and soft, while overcooking makes it hard and brittle.
