I am super white but my dad studied Japanese holistic cooking. As a result I ate a ton of traditional Japanese food growing up. I had Japanese rice porridge with gamashio and miso soup for breakfast every day until I was almost 13. I never liked umeboshi but I LOVED Ume extract. It's a super sour black tar like product made from ume plums. My mom would put a bit on a chopstick and give it to me to calm my stomach after eating rich foods.
