I have a huge soft spot for egg drop soup, specifically the Chinese-American version I first tasted as a kid. You know, the kind that's golden yellow with shards of cooked egg? I assume this fond memory is actually based on a bowl of gloopy, bland, and inauthentic egg drop soup, but that's okay. Luckily, this recipe from Andrea Nguyen's Into the Vietnamese Kitchen is the opposite. It is bright, fresh, and dynamic.
