Hi! If you took your class from Kerry Beal, does that mean you are in Canada? Your profile says U.S., but thought I'd check. We have a few sites in Toronto where you can order from the U.S., also with low shipping cost tot he states, namely VanillaFoodCompany.ca who sells Valrhona, Ghiradelli, CacaoBarry, Callebaut, etc. And I believe you can also order from McCalls (www.macalls.ca) and view your prices in U.S. or Canadian $$s. McCalls sells all types of couverture chocolate, including Lindt (but watch for artificial flavours in Lindt couv.). In Montreal is www.chocolat-chocolat.com - I think you can order tools and packages from the U.S., but I'm not sure about their couvs (they sell Belcolade, Brazilian couv. Boa Sentenca (I have not tasted this) and CacaoBarry, and others).
I personally like Camino's organic and Fair Trade couverture (www.tasteofcamino.com) - their 45% milk chocolate is very nice and easy to work with and their 56% is a great semi-sweet (one of the only organic semi-sweet's you can find). I don't love their 70% for enrobing or bark because of flavour, but it is great in cakes. Cacao Barry also has an organic milk couverture that is very nice, high cocoa butter, 38%. I really like it for enrobing (throublesome for truffles). Their 71% FT/Organic couv is also nice, but disctinct flavour. It pairs very nicely with salt. There is no soy lecithin in this product, good for people concerned with that.
I hope this helps!
