Pad Thai is probably the most famous of all Thai noodle dishes. It’s a classic street food that's often served with prawns or tofu. This dish is always a safe bet to serve because everybody loves it, even the fussiest of eaters. Deliciously sweet and sour tamarind is the key ingredient in this dish. Our ‘secret’ is in the sauce; add a teaspoon of dark soy sauce to the Pad Thai sauce to give it a nice golden brown colour when stir fried.
