Christmas tea is a December tradition for me. It's just strong black tea with plenty of spice and a bit of citrus. I always pick up my blend from a local(ish) tea house.*
I brew it strong and add some milk. Paired with a pumpkin muffin, it's the perfect way to celebrate on a chilly morning.
If you don't have a local tea house with their own blend, I highly recommend Harney & Sons Holiday Tea. The beautiful tin is an added bonus.
