Piece of cake to make yourself and much nicer than anything bought. And one of the few legitimate uses for teabags, apart from soothing tired eyes.
Per person casually toss into a saucepan of appropriate size one teabag, one bayleaf, around 1.5-2 inches of rolled cinnamon bark or a couple of random lumps of the proper stuff, half a dozen cardamom pods and half a clove. Then per person half a mugful of milk and just over half a mugful of cold water. Cook over a medium flame until it starts to bubble then lower the heat and simmer gently for 5-7 minutes. Strain through a mesh sieve and sweeten to taste with sugar or honey if that’s your thing. Job done.
