Rinshin, I wish we had a direct messaging capability, we've connected on so many topics. I know we are local to each other, and after the pandemic, it would be so great if we could have lunch and compare notes. But I guess we'll just have to do it in public and the bored can go on to the next post, LOL.
A number of the items you mention are in my pantry or I buy on demand for recipes.
Coconut Milk - I cheat. I found powdered at an Indian market. It's close enough to have in the pantry without the bulk of cans. More than once I've gone "that needs the edge taken off" and thrown in a couple tablespoons of the powdered coconut milk.
Dried shrimp, dried squid, dried scallops - Haven't found all of these yet. I saw a recipe for making XO sauce in an online article and was going to try it, but it will have to wait for now.
Galangal - sadly I have a food sensitivty, so of course I love the stuff. Strangely I have no problem with ginger, which is closely related. Thai Basil in Sunnyvale (for Rinshin) makes an amazing Beef with Galangal. I get it takeout for myself once every couple years and suffer the consequences.
Maggi Sauce - I did run into this in a recipe recently. But haven't had a need to find it yet.
Mirin - I have several recipes calling for it, but haven't found it yet (not at Whole Foods, BevMo, Total Wine & More or the local Korean supermarket). I've been substituting Sherry.
Miso - Do you have a brand you reccommend? I bought a tub for a recipe I was making and it came out fine. But I decided to make myself a cup of miso broth (so comforting), and it was completely disappointing. Maybe I just didn't use enough.
Toubanjan - Is that the same as Doubanjiang (broad bean chili paste)? I love the stuff! It's the key ingredient in Dali Chicken, a defunct P.F. Chang's menu item that I managed to score the training manual page for (not exactly a recipe, more like an ingredient list) and I managed to reverse engineer a pretty good facsimile recipe. I add add the bean paste to Dal (Indian Lentil) recipes frequently.
