I always do a lot of baking for Christmas...I do 10 types of cookies as well as Peanut Butter, Chocolate and Black Walnut goats milk fudge. I recycle cookie tins and give my goodies as Christmas Gifts. I recently had a batch of Black Walnut fudge get grainy after it cooled and heres a quick fix to make it a useable batch. I put it all broken up back into the kettle, poured 1/2 cup g milk on it and added 1/4 cup light karo, mixed it together and stirred constanly as I brought it up to a slow boil, I do use a candy thermometer so it was brought up to 238*F , shut it off and let it rest 5 minutes. Beat the tar out of it with a heavy wood spoon til it was pretty stiff and poured it into a buttered pan. I left it cool before I cut and the re cook did the trick..it was smooth and wow did the flavor of those Black walnuts intensify. This also works well for too hard chocolate fudge, just re cook with a bit of milk and stir constantly to prevent it from sticking and scorching.
