practicality

My default is fresh scallions, fresh ginger, and roasted shrimp (https://www.thekitchn.com/how-to-roast-shrimp-in-the-oven-cooking-lessons-from-the-kitchn-204080), plus a dash or two of fish sauce. I've seen chunks of white fish (like sea bass or cod) as a congee topping in takeout joints.
