This is a simple recipe for crushed coffee jelly that can be made with just canned coffee and powdered gelatin. Add 5g of powdered gelatin to 40ml of coffee that has been brought to room temperature beforehand, and heat in the microwave for 20 seconds until dissolved. Pour this back into the coffee bottle, put the lid on, shake gently to mix, and then refrigerate for 5 hours to set. Once set, shake to crush the jelly, pour into a glass, and enjoy with toppings such as milk, whipped cream, or honey. The appeal of this recipe is that you can easily make delicious coffee jelly with your favorite canned coffee, whether black or café au lait.
