Any ideas where to find this ingredient ,ideally in central Toronto. It's used as a stabilizer in gelato.
Bob's Red Mill makes Xanthan Gum -- So, you might find it at a grocery store that has a broad selection of Bob's Red Mill products.
I've purchased it at the Lively Life in the basement of SLM in the back of the store. My guess is Dominos in the basement of SLM has it as well since they have such a large selection of bulk goods and powders.
You can get it at loblaws. Bob's red mill brand. Its pretty cheap, $10 for a fairly large bag. I've seen it at the loblaws at Queen West and Portland St many times.
