If anyone out there has any idea on this, please let me know. The boil time for the original recipe is 5 minutes. I need to double the sauce recipe so I am wondering if I have to double the cooking time as well.

Nope.

I'd boil for 7-8 minutes.

Thanks for you response.

Can you get a "feel" for it the thickness, etc? Do you do enough cooking?

Yep. I've done enough cooking so that shouldn't be a problem. It comes out so good in a single batch I just don't want to mess up a double batch by overlooking the boiling time.

Watch the texture and color. If sugar crystals gather along the sides of the pan during the cooking process, you can use a pastry brush dipped in water (or even the spoon) to brush the sugar down the sides of the pan so that it becomes incorporated into the boiling mixture.

No. A general rule of thumb when it comes to cooking on a stovetop is - even when you double the ingredirnts, you don't have to double the time. It doesn't always work like that, but it applies in this case. =)
