Dough Ingredients: Water, Flour, Cream of Tartar, Salt, Vegetable Oil,& essential oils if applicable. Supervision recommended for all smaller pieces. Average Shelf life is 2-3 months, even longer if stored airtight. Please plan accordingly when ordering as you don't want dough sitting untouched.  If small crystals form, it's just salt, add water and knead and dough will come back to life!
