One of the most common doubts people have is - if there's any difference between Biryani, Pulao and Tehri and people tend to us these words interchangeably.
The main ingredients (rice, meat/vegetables and even spices) are almost the same - it is the difference in the cooking method that gives different taste and three different dishes. Biryani is cooked in layers of meat/veg and rice, while in pulao both ingredients are cooked almost together and Tehri is somewhere in between. Pulao is made predominantly with dry fruits while in Tehri it is the dominance of vegetables. Pulao is rarely a whole meal implying you usually need a side dish, or gravy while Tehri is a wholesome meal comprising of vegetables and rice. Traditionally Tehri was coceptualised with just potatoes and rice but over time other vegetables made their way in leading to a more colorful, more delicious and more nutritious dish.
