Vanilla Marshmallows

Ingredients

Directions

Prepare the syrup

  1. Dissolve gelatin in hot water and set aside.

  2. In a kettle, combine glucose and cook until it reaches 248°F (hard ball stage).

  3. Remove from heat and add granulated sugar.

  4. Strain the sugar mixture into the gelatin mixture and add vanilla extract.

Whip and set

  1. Beat the mixture until stiff using a marshmallow beater.

  2. Pour onto a slab that is heavily sprinkled with XXXX sugar.

  3. Spread evenly with a palette knife and sprinkle more XXXX sugar on top.

  4. Let it stand for 4 to 5 hours.

Cut and serve

  1. Cut into squares without dragging the knife; press down to cut.

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.

    Shared aroma: ethanol (alcoholic, ethereal).

    Shared aroma: beta-damascenone (apple, rose).

    Shared aroma: maltol (caramel, sweet).

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

Gelatin
Forms the elastic gel network that gives marshmallows their springy, airy structure.
Glucose
Inhibits sugar crystallization, keeping the marshmallow smooth and soft rather than grainy.
Granulated sugar
Provides sweetness and bulk to the syrup that is whipped into the foam.
Hot water
Dissolves the gelatin so it can blend evenly into the sugar syrup.

The step that matters

Cook the glucose to 248°F (hard ball stage). The syrup's final temperature sets how much water remains. Undercooking leaves marshmallows soft and sticky, while overcooking makes them tough and hard once cooled.
