Best place to buy verjus online? I've been reading up and want a chance to play with this most interesting ingredient.

www.markethallfoods.com also sells some. They have some great stuff!

Kalustyan's, an incredible mail-order source for spices and all kinds of esoteric pantry goods, carries 2 types of verjus -- one from France and one from Long Island, NY: http://www.kalustyans.com/
