I made this last July 14 on vacation in Massachusetts. The plan had been to go to Maine, but Covid derailed that. We made some Maine recipes anyway. This is from the Maine Bicentennial Community Cookbook and is credited to "State Prisoner Matthew." The recipe uses ingredients and tools available to the inmates. I thought it was delicious and had a fascinating texture (was it supposed to? I don't know, but ours did)-- soft/chewy fudge, but also kind of like a butterfinger with ribbons of crystallized sugar.
1 1/2 jars peanut butter
1/2 jar Fluff
1 - 1 1/2 c sugar
1 bag M&Ms (maybe we used peanut butter M&Ms?)
Empty peanut butter and Fluff into a large bowl. Microwave until it starts to rise. Take it out and stir. Let sit. When cooler, mix in M&Ms, if using.
Pour a small amount of water in a separate bowl with the sugar. Mix. It should be thick. Microwave until it begins to boil. Take it out and stir for 10 seconds. Put it back in the microwave and let the sugar boil until it turns a golden brown sugar-- it should be at the point of crystallizing. I suppose you could also do this on the stove unless you're in prison.
Pour the sugar mixture into the PB/Fluff mixture. Quickly!! stir-- the fudge will begin to harden fast. After mixing well, pour into a greased pan (or if, in prison, a box lined with a trash bag). spread it out evenly with a spoon and press it down with a gloved hand. Let sit for 1.5-2 hours.
