Heat the raspberries, sugar and water in a saucepan over medium low heat. Whisk until the sugar is dissolved. Let the mix lightly simmer for 4 to 5 minutes, until the berries break down. Pour the mixture through a fine mesh sieve into a jar to strain out the seeds. This stays great in the fridge as long as it’s in a sealed container!
Fill the glasses with crushed ice and pour 2 to 3 tablespoons of the syrup over top – however much you would like! Add you desired amount of espresso (hello multiple shots) and fill the rest up with milk. Garnish with a berry or two. Enjoy!
