Tauco (bean paste sauce) is one of my must have pantry ingredient. It is commonly used in both Indonesian and Chinese dishes. It elevates any regular stir fry into something more. You can easily add a tablespoon or two to your trusted stir fry recipes, but remember to adjust for saltiness since this is salty by nature. If you have no idea what tauco is, this salted soy beans from Yeo is the one I use here in the United States. My local asian groceries carry them, so if your house is close to one, buying from brick and mortar store is usually cheaper than online.
