You can also use a mixture of 1/2 apple juice and 1/2 apple cider.
There are two ways to mull cider. The first is just like mulling wine. Place the mulling spices in the muslin bag and simmer in water for 20-30 minutes. This will reconstitue the spices. Discard the water, add the gallon of apple juice or cider (retaining the spices) and warm. The spices will flavor the juice in about 15 minutes.
You can also use a coffee urn to make mulled cider in larger batches. Place the mulling spices in the top of the urn where the coffee would normally go. (3 Tbsp per gallon of juice). Pour the juice in the bottom of the urn and let perculate to mull the cider. This is great for parties.
To dress it up, serve in mugs with a cinnamon stick and a slice of orange.
