Dianne, hello again. Brown Sugar Twin, is just that. Sugar Twin is a sweetener made with Aspartame that is readily available in North America. Brown sugar twin is just a brown sugar version of it. I have a box of it at home, but have yet to use it. The reason behind the combining of artificial sweeteners is that they don't taste exactly like sugar. A mix and match helps with this. There are a few tricks to low carb cooking that you'll learn as you go along.

Yes, it can be more expensive than high carb, because you do end up doing so much cooking, and then there's the meat But I have found it evens out. I bring everything I eat to work now. Nothing sits in the fridge at home and goes bad because we don't eat it. The artificial sweeteners do cost more than sugar (lets face it, sugar's cheap) but they are also MUCH sweeter and you use MUCH less.

Take care,
Nat
