Does your no boil kit call for sugar? If it does, you can consider the DME (dry malt extract) a replacement for the sugar. I'd just boil up a little water (subtract it from the amount in the kit), like a quart, and then dissolve the DME in it. Since it's already been boiled when it was made, you can just boil it a little to make sure it's dissolved, then cool it and use it in your no-boil kit.
