Comfort food from back in the day: Heinz cream of tomato soup with weird little DIY dumplings I make by scooping out those terrible supermarket bagels and mushing them into little balls.
Fancier: chunky chicken soup with veggies. Throw in some soft roasted garlic; they're like little flavour packets!
Fanciest: kitsune udon soup. I know it's not considered fancy in Japan, but I don't live in Japan, so I can only access it in fancy contexts.
Best I've ever had, but have also never had since: cream of artichoke at a local art festival in Pescadero, California. It was incredible.
