This bottle measures, mixes, serves, and stores sauces quickly and easily. Helen developed 4 authentic Asian stir fry sauce recipes and had them printed right on the glass bottle with permanent markings which won’t fade or wear off. Measure ingredients right into the bottle, cap, shake and pour one of the 4 recipes - Mandarin Orange, Canton Oyster, Beijing Hoisin or Sichuan Spicy Black Bean sauce - to easily create an authentic Asian stir fry. Cooking instructions are included. Dishwasher safe and made in the USA.
