On the topic of strings…why are they always yellow?
Hello, Tegan!
They used to mix egg yolk with silk for the purpose of make it sound sweet. And also a kind of yellow ginger called UKON was mixed to avoid moth. The color is the relic of such custom.
UKON is also known as turmeric. It is both a spice and a dye, which you might discover if you spill curry on clothes, and then find a new color that won’t wash out. Turmeric came to Japan on the Silk Road, I think. It is rarely used in Japanese food, but common as a dye. In Okinawa, they grow turmeric and make tea and such with it. Ironically, it is not used in the sanshin strings.
