Mulling spices are a European spice mixture that are used in drink recipes. You can add it to juices, apple cider or tea. A mulled drink is one that has been prepared with these spices (usually through heating the drink in a pot with mulling spices and then strained). You can use a combination of spices. Usually it consists of cinnamon, cloves, allspice and nutmeg. Less frequently you can use star anise, peppercorn and cardamom. You also can add dried fruit such as raisins, apples or orange rind.
My preference for simmered mulling spices for scent is different than the one I would use to drink. 120ml Mulled Spice Tins can be ordered on my online shop as well.
