Frozen Coffee

Ingredients

Directions

Make the coffee

  1. Grind the coffee finely and place it in a gallon jar that has been scalded with boiling water.

  2. Boil 3 quarts of water in a kettle, then pour it over the coffee and stir well.

  3. Cover and let it sit in a warm place for 5 minutes, stirring occasionally.

  4. Let the mixture settle, then pour off the clear coffee through fine muslin.

  5. Add water to make a total of 3 quarts and dissolve the sugar in it.

Freeze and serve

  1. Cool the mixture, then place it in a freezer.

  2. Add the egg white and freeze until it reaches a soft mush consistency, like wet snow.

  3. Serve in tall goblets.

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

What each ingredient does

Fresh roasted coffee
Provides the coffee flavor that makes up the base of the drink.
Sugar
Sweetens the coffee and lowers its freezing point, keeping the frozen mixture soft.
Egg white
Whipped into the partly frozen mixture to add air and give a light, soft texture.

The step that matters

Freeze until soft mush, like wet snow. Freezing must stop before the mixture turns solid. Ice crystals form as it cools, and stirring or whipping breaks them up into fine crystals. Freezing too long leaves a hard, icy block that cannot be spooned or whipped into a smooth texture.
