Chocolate Mousse In A Kilner® Jar


  • 70g/ ½ cup dark chocolate, plus more for garnish
  • ½ tsp. unsalted butter
  • ¼ tsp. instant coffee powder
  • 1 egg, separated
  • Chopped nuts (optional)


Break up the chocolate and place in a heatproof bowl over a saucepan containing an inch of simmering water. It is important to make sure the bowl does not touch the water.

Add the butter and melt with the chocolate, stirring frequently, then add in the instant coffee powder.

Remove from the heat and allow to cool for 2-3 minutes. Add in the egg yolk and beat together until a smooth consistency is reached.

In another bowl, beat the egg white until stiff peaks are formed. Gently fold the egg whites into the chocolate mixture using a metal spoon.

Spoon the mousse evenly among the Kilner® jars then sprinkle with finely chopped chocolate and optional chopped nuts.

Close the lids and secure the clips. Chill in the fridge for at least 2 hours or until ready to serve.

Label your tags and add ribbon to serve. Enjoy.
