Key Limes Making Drinks
Key Limes were $1.50 for 10 at Granville Island. They are difficult to mash up for juice, but they are the right taste for mohitos.
Bamboo Shoots
This is the root of the bamboo tree and the prices are very reasonable - the same price in Canada generally buys a much smaller root that has been preserved.
Tsukemono (Japanese Pickles)
There are about as many varieties of pickles as there are towns in Japan. Nice places have little sample boxes that let you taste them because there is a huge variety in the flavors available.
