Coffee Essence
Ingredients
Directions
Make the essence
Simmer the coffee grounds in boiling water, ensuring the mixture does not boil.
Filter the mixture into a clean, dry bottle and cork it well.
Serve
Add 2 tablespoons of the essence to a breakfast cup of hot milk.
For a better coffee, use the weak coffee made from the grounds next time you prepare the essence.

What each ingredient does
- Coffee grounds
- Provide the coffee flavour and aroma that the essence is built on.
- Hot milk
- Softens the coffee's bitterness and adds richness and body to the drink.
The step that matters
Simmering without boiling. Keeping the mixture just below a boil extracts flavour gently. A hard boil pulls out more bitter compounds and can scorch the grounds, giving a harsh, burnt taste.
