Soak the noodles in lukewarm water for 10 minutes, then drain.
Blend the chilli, shallots, garlic, dried shrimp and shrimp paste into a paste.
Heat the oil in a wok and fry the spice paste over medium heat for 8 minutes until fragrant and the oil separates out. Remove half.
To the paste left in the wok, add the water, tamarind, soybean paste and sugar, bring to the boil, add the shrimp, and cook for 3 minutes. Season with salt; this is the sauce.
In another pan, fry the drained noodles and half the bean sprouts with the reserved paste for 3-4 minutes until the noodles are heated through and reddish.
Divide the noodles among bowls, ladle over the hot sauce with the shrimp, and serve with tofu, egg, bean sprouts, chives and lime wedges.

Tips
Squeeze the lime over just before eating — it gives the fresh sourness.
The spice paste can be made ahead; keeps for a week in the fridge.
