There are lots of different teas that are not fruity. My favorite comfort teas are Mint (Bigelows Mint medley is xtra good), pumpkin spice, different types of chai, there is a vanilla rooibos at Bulk Barn that is very tasty. Sometimes I have these with cream, or coconut milk, or blended with butter or coconut oil to thicken them up.
I also put cocoa powder right in my coffee or tea with some cream - delicious, and better than "plain"!
