Does it have to be corn syrup? Would golden syrup be a suitable substitute?
jrh065 Kiteman3 years ago
I'll bet any syrup will do so long as the water content is low enough. Either way you should be able to cook the water out.
One effect the corn syrup has which the golden syrup may or may not have is to help keep the sugar crystals dissolved and make the candy smoother.
Hmm, what do I know, but I'm guessing sugar water, boiled down to make a sticky syrup, might work just as well.
I did it for 8 and it came out black! help?
It could be you have a more powerful microwave!
not much science, but looks good! can't wait to try it. oh yeah, how long does it take to cool?
I just left it in the fridge for an hour or two!

I made good peanut brittle on a stovetop with a pan when we lived in Ohio. The wintertime humidity was low. I tried a microwave recipe in the summer while we were visiting Tennessee. The humidity was much higher and the peanut brittle never got hard. Humidity is a variable that will greatly affect the results.

I do this all the time, just be careful after you microwave the stuff. It turns basically into napalm, you get it on you its going to stick and burn you.
