Coffee Extract

Ingredients

Directions

Prepare the beans

  2. Cool the beans in open air without adding water.

  3. Grind the roasted beans.

Extract

  1. Place the ground beans in double gallon cans and cover with hot, boiling water.

  2. Seal the cans air-tight and process for two hours at 240°F (115°C).

Finish

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

What each ingredient does

Roasted coffee beans
Provide the main coffee flavor and dark color once ground and steeped in water.
Double proof alcohol
Dissolves the aromatic compounds and benzoin, carrying flavor through the extract.
Benzoin
A resin that adds a warm, sweet aroma and helps fix the scent in the extract.
Orange flower water
Adds a delicate floral aroma.
Tartaric acid
Adds a sharp acidity that brightens the flavor.

The step that matters

Dissolve the benzoin in the alcohol first. Benzoin is a resin that dissolves readily in alcohol but poorly in water. Fully dissolving it in the alcohol before adding the other ingredients keeps it from clumping or settling out of the extract.

Swap the beans

How well each one fits the dish's main ingredients (coffee, almond, orange, lemon, spirit):

  1. Walnutfits better
  2. Pistachiofits better
  3. Hazelnutfits about as well
  4. Beansthe original

Fit is the average pairing score against coffee, almond, orange, lemon, spirit. Candidates are from the same food group and used in at least 100 recipes.
