Genmaicha is a Japanese tea that is made with a combination of green tea and roasted brown rice.
Genmaicha tea has a nutty flavor that tastes like you're drinking a popcorn flavor tea. The popcorn flavor comes from the roasted brown rice.
During the roasting process, the rice will occasionally get 'popped' and produces little white fluffy bits that actually look like popcorn!
Genmaicha is most commonly used as tea, however, you can also use it in brines and marinades as well but the process still involves it being steeped into a tea before using it as a brine or marinade.
You can find genmaicha at Asian tea stores and Asian supermarkets. Now that tea is getting more and more popular you can almost always find them at almost all tea stores as well.
This green tea comes in either tea bags or in loose leaves. I personally prefer using loose leaves because you have a bit more control over how strong you want your tea by putting in the amount you need.
Store any type of tea in an air-tight container away from sunlight in a cool dark place.
