Mexican Sugar Candy

Ingredients

Directions

Make the candy

  1. Heat 1 cup of sugar in an iron saucepan until it melts, being careful not to let it burn.

  2. Remove from heat and let it cool slightly.

  3. Add the milk and the remaining ½ cup of sugar, stirring to combine.

  4. Cook the mixture until it reaches the soft ball stage.

  5. Remove from heat and add the pecans.

  6. Stir until the mixture granulates.

Set and serve

  1. Pour into a greased shallow pan.

  2. Flatten the mixture quickly.

  3. Let it cool before breaking into squares.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 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

Pecans
Add texture and a toasty, nutty flavor that contrasts with the sweet candy base.
Milk
Adds moisture and creaminess, and its proteins and sugars help give the candy a soft, smooth body.
Granulated sugar
Provides sweetness and, once melted and cooked, forms the crystalline structure of the candy.

The step that matters

Stir until the mixture granulates. Stirring a cooked sugar mixture controls crystal formation. Stir too little and the candy stays glassy or soft; stir too long after it has begun to set and it hardens before it can be poured and flattened.

Swap the pecans

How well each one fits the dish's main ingredients (sugar, milk):

  1. Cocoafits better
  2. Almondfits better
  3. Chestnutfits better
  4. Pecansthe original

Fit is the average pairing score against sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
