Soak the rice noodles in warm water for one hour. Boiling them to cook aids in their demise, so don’t be tempted unless you’re okay with soggy noodles. If you are, no judgement because sometimes I like them too.
Make tamarind water by mashing the tamarind pulp and 45 millilitres of hot water in a small bowl. Fork and/or hands will suffice. Use the back of a wooden spoon or silicone spatula to press the pulp against a mesh strainer, sieving the thick-ish liquid into another small bowl. Be sure to scrape the thick goop from the bottom of the strainer. Discard the solids left in the strainer. Mix the palm sugar, soy sauce, and salt into the tamarind water.
Once the noodles are soaked (the consistency will be bouncy with a little firmness, and they won’t taste like they’re ready to eat yet), heat a wok to medium high heat. Once hot, add the oil.
Stir fry the tofu, shallot, and preserved radish for a few minutes, just until the tofu begins to colour. Add the noodles and the tamarind sauce, continuing to stir fry for about a minute. If the noodles don’t soften a little under the heat, toss a tablespoon of water in to aid in softening.
Add most of the bean sprouts and Chinese chives, stir-frying just until wilted.
Dish up, garnishing the noodles with the remaining sprouts and chives, plus a sprinkling of peanuts and toasted chilli powder. Serve with a slice of lime.
