Hi Umpa,
I use cocoa daily (hot chocolate or choc shake). Every little carb saving counts.
While we do have at least one good online store in Australia for low carb products (
www.lowcarbcentral.com.au) our supermarkets have nothing that is specifically low carb. It is very hard to find anything sugar free that does not contain malitol and similar "tummy" issue products. I keep waiting for the low carb penny to drop...taking a long time I must say.
I mostly use regular foods (meat, veges, cream cheese, cream, frozen berries) but it is nice to have a good supply of low carb items to supplement things.
I would order the Lion zero carb cocoa if it was available online - have not found it anywhere so far though.
Another thing we do not have here is unsweetened baker's chocolate. The closest I have found is cooking chocolate but it contains about 55 c per 200g block (similar to Lindt).
We Aussies just have to be more inventive to keep things interesting. Sites like yours help tremendously!
