Is "sucanat" the same thing as that raw sugar in a box?

They're not the same thing, but you can use them interchangeably.

Here's a good article on the difference: http://www.ehow.com/about_5374032_turbinado-vs-sucanat.html (Did I really link to an eHow article? Yes, yes I did. You may admonish me forthwith).

• Turbinado (a.k.a. Sugar in the Raw) = cane juice that's heated to its crystallization point.
• Sucanat = cane juice that's dried/dehydrated.

Sucanat has more of the original molasses content.

Trivia. There are few things in the world that smell as awful as the production of turbinado. I'll take a vacation to a pig farm over one to a turbinado processing plant.
