Plain Chocolate

Ingredients

Directions

Prepare the chocolate

  1. Heat the milk in a double boiler.

  2. Scrape the chocolate finely and place it in a small frying pan with the sugar and water.

  3. Set the frying pan over medium heat and stir constantly until smooth and glossy.

Make the chocolate milk

  1. Stir the chocolate mixture into the boiling milk.

  2. For a thicker chocolate, mix the arrowroot or corn-starch with 2 tablespoons of cold milk, stir into the boiling milk, and cook for 10 minutes before adding the dissolved chocolate.

  3. Add vanilla if desired.

  4. Beat with a whisk for three minutes and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chocolate
Provides the main chocolate flavour and colour of the drink.
Milk
Forms the liquid base and gives the drink its creamy body.
Sugar
Adds sweetness to balance the bitterness of the chocolate.
Arrowroot or corn-starch
Thickens the milk when cooked, giving a heavier body to the drink.

The step that matters

Dissolving the chocolate smoothly. Chocolate must be melted slowly with sugar and water and stirred constantly, because overheating or skipping the stirring can make it grainy or scorched rather than smooth and glossy.

Swap the arrowroot

The recipe marks arrowroot as optional. How well each one fits the dish's main ingredients (chocolate, milk, sugar, vanilla):

  1. Arrowrootthe original
  2. Sweet potatofits about as well
  3. Capsicumfits less well
  4. Potatofits less well

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