Johnny Iuzzini's Chocolate Soup

Melt the chocolate in a glass bowl in the microwave in 30-second bursts, stirring between each burst, or melt in a double boiler. Roll the Cocoa Puffs in the chocolate, coating them completely. Lift them out with a fork, letting the excess chocolate drip off, and place on a parchment-lined baking sheet to set. Store in a cool place.
Put 1 cup of the milk in a small saucepan with the juniper berries. Bring to a boil, then turn off the heat and let the juniper infuse for 25 minutes. Have the chopped chocolate ready in a heatproof bowl, and, remember, the finer you've chopped the chocolate, the better.
Bring the milk back to a boil, then strain into a measuring cup. Add some of the remaining 3 cups milk, if needed, to make 1 cup. Pour the hot milk over the chocolate, let it sit for a moment, then whisk to melt the chocolate and make an emulsion.
Pour in the rest of the cold milk, and froth the soup with an immersion blender. Transfer to a pitcher and refrigerate until you're ready to serve.
Whisk the heavy cream and Devon cream together in a bowl until thick. Whisk in the milk, then froth with an immersion blender (add additional milk if you need to). Transfer to a pitcher and refrigerate until you're ready to serve.
Thin the chocolate soup with some cold milk if it's too thick to sip, and froth it again with an immersion blender.
Divide the soup among sixteen small glasses (for tasting portions) or among eight coffee cups. Drop in a few of the Cocoa Puffs, then spoon on a layer of the Devon foam. Top with a few more Cocoa Puffs.
