Combine the apple cider, orange slices, cinnamon sticks, cloves, star anise, maple syrup and nutmeg in a large pot or slow cooker.

Bring to a gentle simmer over medium heat, about 10 minutes, without letting it boil.

Reduce the heat to low, cover, and simmer 15 to 20 minutes, letting the spices steep until the kitchen smells warm and the cider turns deep amber.

Strain out the solids with a fine mesh sieve, or leave them in and ladle around them.

Ladle the hot cider into mugs and garnish each with a fresh cinnamon stick and an orange slice.
