One of my coworkers was married to a Laotian woman and as such married into a large Laotian community. One day we went to the Asian supermarket and we bought all the stuff to make green papaya salad and larb. He brought three specific things from home for this: a weird aluminum cauldron, a bamboo basket to put on it (to make sticky rice) and a repurposed instant coffee bottle full of the strangest looking sludge. It looked kind of like peering into a chewing tobacco spit bottle. This was a bottle of homemade padaek[1] and he said it was like liquid gold in the community he lived in. It was foul as hell to smell but we did a taste test of the papaya salad before and after mixing it in and sure enough it was so much better with the padaek. It was an eye opening experience and since then I've always had a fish sauce bottle in my fridge. I even use a little of it in things like spaghetti sauce.
Anyway if you have a chance to get your hands on a little homemade padaek, definitely do it. Would kill for some, myself. Also, share new foods with friends if they are open to it. I am very fond of that memory. I had never been exposed to those dishes before and even that small experience broadened my world in a simple, but meaningful way.
