I used Celestial Seasonings Bengal Spice tea for this recipe. I don't know if any other tea companies make Bengal spice but I know that Celestial Seasonings is available in most grocery stores. About the muffins: The first time I made this recipe, the muffins rose up nicely but were very dry. I adjusted the ingredients, and, the second time, the muffins were a little flat but they were so incredibly flavorful, sweet and moist that I didn't want to make any more changes. So, if you can deal with a slightly flat muffin, the taste will be well worth it. P.S. The muffins are dairy-free!
