Put the sugar, cocoa, salt, coffee and cinnamon stick in a large pan with 600ml (1 pint) of water. Bring slowly to the boil, stirring, until the sugar has completely dissolved. Boil for 5min, then remove from the heat. Leave to cool. Remove the cinnamon stick, then chill.
Step 2
Pour into a freezerproof container and put in the coldest part of the freezer until firmly frozen. Remove from the freezer, put the frozen mixture into a blender or food processor and blend until smooth. Working quickly, put the mixture back in the container and return to the freezer. Freeze for at least 1hr. Alternatively, put mixture into an ice cream maker and churn for about 30min until firm. Store in freezer until needed.
Step 3
Scoop out the sorbet and put into individual cups, then pour 1tsp liqueur over each one and serve immediately.
An experienced and highly skilled team of food writers, stylists and digital content producers, the Good Housekeeping Cookery Team is a close-knit squad of food obsessives. Cookery Editor Emma Franklin is our resident chilli obsessive and barbecue expert, who spends an inordinate amount of time on holidays poking round the local supermarkets seeking out new and exciting foods. Senior Cookery Writer Alice Shields is a former pastry chef and baking fanatic who loves making bread and would have peanut butter with everything if she could. Her favourite carb is pasta, and our vibrant green spaghetti is her weeknight go-to. Lover of all things savoury, Senior Cookery Writer Grace Evans can be found eating crispy corn and nocellara olives at every opportunity, and will take the cheeseboard over dessert any time (though she cannot resist a slice of tres leches cake). With a wealth of professional kitchen know-how, culinary training and years of experience between them, they are all dedicated to ensuring every Good Housekeeping recipe is the best it can be, so you can trust they’ll work (and if they don’t – we’ll have the answer for why*) every time (*90% of the time the answer is: “buy an separate oven thermometer”!).
