Had this in a travel mug today, and I’m quite impressed with how well it holds up to my modifications AND a morning in a mug.
I added 1 tsp of english breakfast to 1.5 tsp of this in a 16 oz mug. The english breakfast helps the tea flavour come out more, and the spice in the pumpkin pie tea is more than enough to deal with the added tea leaves. Just a little soy creamer to make it taste richer and more dessert-y, and ta da! Delicious tea in a travel mug.
