Thankfully, being told name brands to look for also makes a huge difference. My cooking instructor suggested Three Crabs Fish Sauce. If you can't read the label, at least you can find one with 3 crabs. But then at the store, they also have Five Crabs Fish Sauce. Seriously? Is 5 better than 3? I went with 3 because that is what she told me.
My instructor pointed out one thing about Thai food is that it requires a lot of prep work, but cooks up quickly. She said it's really perfect for busy weeknight dinners if you can get the prep work done in advance. All you'd have to do it toss the ingredients in a pot. Cooking time is really fast, maybe 20 minutes if you are slow. This curry only took me 15 minutes of actual cooking time.
