1. I've tried every rice stick sold at supermarkets in Australia. Chang's is the best - it's less prone to breaking when it's tossed in the pan. See photo in post. If you can't find Chang's, use another that is 2 - 3 mm / 0.1 " thick. Avoid wider rice noodles, they are more prone to breaking.
If using the the Erawan brand rice noodles (see photo in post), soak in room temp tap water for 40 - 45 minutes until noodles are silky but still a touch firm. DO NOT follow the packet directions to boil - they disintegrate in the pan!
125g doesn't sound like much noodles but they expand when soaked.
2. Tamarind is the heart and soul of Pad Thai. The authentic version starts with tamarind pulp which needs to be soaked then strained. Puree is sold in a jar at supermarkets (Asian section), far easier! It's a scoopable soft paste (see video).
It can be labelled as Tamarind Puree, Concentrate or Paste. In Australia it's sold at Woolies, Coles, Harris Farms (Asian section) as well as Asian stores. There's a few different ones on Amazon US - here is the cheapest one
Use leftovers for Beef Rendang
if you can't find tamarind. Use this for the Pad Thai Sauce instead of ingredients listed above:
1 tbsp ketchup, 2 tbsp brown sugar, 2 tbsp fish sauce, 2 tsp oyster sauce, 1 tsp dark soy sauce*, 2 tbsp rice vinegar (or 1 tbsp white vinegar).
See in post for explanation, and cynics, don't judge until you've tried this! It's remarkably good and quite close to the base Pad Thai recipe!:
* This is mainly for colour, so can be substituted with light or normal soy sauce and flavour will still be the same.
3. Can be substituted with light soy sauce though you will lose a bit of the flavour edge that fish sauce gives it.
4. Not in authentic Pad Thai but is essential for this everyday version.
5. Garlic chives look like blades of grass and taste like garlicky chives. If you can't find them, it's not a deal killer. Best to substitute with chopped shallots (aka green onion / scallions)/..
6. General note: I use a skillet here, I find it easier. But if you have a well seasoned wok, make it in that if you want!
7. Nutrition per serving, assuming 2 servings. The weight doesn't take into account the water absorbed by the noodles. I think it's closer to 350g / 12oz per serving. It's a generous serving!
