Galangal and Kaffir Lime Leaves
Available fresh and frozen at the Cherry St T&T, and likely at any store featuring Asian produce. T&T does, indeed, label galangal as "white ginger".
The fresh lime leaves are amazing. A little goes a very long way, so I freeze them at the first signs of drying. The flavour and aroma, while somewhat weakened, remain wonderful.
I have bought both of these from the shop in the centre-north are of the basement level of the SLM.
I have also bought them from Oriental Harvest (or whatever it is called), the basement grocery store on the west side of Spadina just south of St. Andrew.
I have also bought both from T&T.
