I've had a Thai cookbook for the past year or so which I've been meaning to try some recipes from, but I got stalled every time I did because I couldn't find all the ingredients at my typical grocery stores. Luckily, there are a few specialty grocery stores in the DC area that sell Thai groceries, and one in Silver Spring a short walk from the Silver Spring metro, called
Thai Market.
As a huge food nerd, I thought this was a lot of fun. It was exciting to walk around a store with such a variety of unusual (to me) ingredients and pick things to try. In general, they have much more dried and canned items than fresh foods, but I found almost all of what I was looking for. And for really good prices.
I bought: a couple types of dried red chiles, fresh green chiles, dried shrimp, jarred shrimp paste, oyster sauce, fresh lemon grass, fresh Thai basil, cardamom pods, garlic, dried kaffir lime leaves (which smell amazing), soba noodles, and several packages of really awesome-looking rice noodles for making Pad Thai and Drunken Noodles later.
I wanted to buy, but didn't want to carry home, one of their huge bags of jasmine rice.
They also had several types of coconut water and juice and lots of types of soy sauce and fish sauce... and a lot more.
I spent $50 on all of this, which I feel like is a really good price for the number of things I bought, especially since spices and sauces are usually expensive at regular grocery stores. I've been having fun trying out some of the things I bought, and will have a lot on hand for a while, so this is definitely a good place to go and stock up. And I'm sure I'll be back.
