I got a recipe that asks for "frozen ube, thawed", and looking around my local stores and a quick google shopping search has failed to bring up any frozen ube, but I have found I can order fresh ube. Seeing some of the similar questions about fresh vs. frozen has me worried that it might not work or that I might have to do something besides sticking it in freezer and later taking it out.
Other details that I guess might be helpful: The recipe is for bread for an extra blue blueberry jam sandwich with extra batter being used for blueberry muffins (will consider doubling each ingredient to ensure extra batter). The frozen ube is apparently counted as one of the wet ingredients to be mixed with the other wet ingredients before being combined with the dry ingredients.
EDIT: Oh, and the recipe calls for 16 ounces of the "frozen ube, thatwed".
