Could probably make a thread just on Korean non-tea teas.

Honey Yuja is kind of like a marmalade made from Chinese Citron (Yuzu in Japanese) and honey. To make it you just dissolve a a couple of teaspoons into hot water, I'll even eat the remaining rind and pith. One of the joys of entering the cooler months, love a hot cup of Yuzu cha on a cold day!

Sort of similar to Yuja tea is Korean honey plum tea (you can get lovely brews based on umeboshi in Japan which aren't as sweet).

Last winter I got into making Daechucha as I had been given a couple of bags of jujubes (Chinese dates) http://1tess.wordpress.com/2011/02/2...tea-daechucha/
Really warming with the ginger. The pine kernels aren't essential but I love the fragrance they give to the drink's steam.

I've no doubt there are plenty more kinds from Korea, I always welcome the opportunity to try new tisanes (and real teas)
