Add the yeast to the warm water and let it sit for 5 minutes. Mix flour, salt, cinnamon, and tea in a bowl. Make a well in the center and add the yeast, pumpkin, and olive oil. Mix into a dough. Turn onto a floured surface and knead for 10 minutes. Cut into 8ths and shape each into a ball. Using the twine, wrap each ball into 8 sections. Place on a baking sheet and brush lightly with olive oil. Cover with parchment paper and let rise for 1 hour. Bake for 15 minutes at 400 then cut the string off. Enjoy with whipped cinnamon butter
