Vanilla Cream Bars

Ingredients

Directions

The book gives no oven temperature. The 243°F in the steps was added when the recipe was transcribed, as a starting point.

Make the syrup

  1. Dissolve the sugar in water in a clean pan.

  2. Add the glucose and boil until it reaches 243°F (degree of feather).

  3. Pour the mixture onto a damp slab and let it cool for a few minutes.

Work the cream

  1. Use a palette knife to work it into a smooth white cream, adding a tint of blue to bleach it.

  2. Once smooth, return it to the pan and melt just enough to pour out smoothly.

  3. Stir in the vanilla flavoring and pour onto a plate to a thickness of ½ inch.

Set and cut

  1. Allow to set, then cut into bars.

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: beta-damascenone (apple, rose).

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

White sugar
Forms the crystalline body of the cream and provides sweetness.
Glucose
Interferes with sugar crystal formation, keeping the cream smooth and soft rather than grainy.
Vanilla flavoring
Adds aroma and flavor to the finished cream.

The step that matters

Boiling to 243°F (degree of feather). The boiling temperature sets how much water remains in the sugar syrup. Stopping short leaves a soft, sticky mass that will not hold its shape, while going too far makes the cream hard and brittle.
