Here are the tangsuyuk elements: pickled veggies, un-pickled mushrooms (pyogo, i.e., shiitake), fried pork, soy sauce, and dragonfruit sauce. Goodness awaits.
The marinating veggies (lower right) are: red chilis, green chilis, cucumbers, carrots, and green bell peppers. The pickling solution, which was designed to be a mere gentle bath to kick up the veggies' flavor only slightly, was a mixture of water, apple vinegar, sugar, and chili flakes. After an hour or so, the veggies had all taken on a delightfully sweet-sour-spicy complexion. After that, it was just a matter of draining and stir-frying, all of which turned out perfectly, thank Cthulhu.
