Lemon Fudge

I was asked by several people today to post the recipe for the lemon fudge I brought today. The actual recipe was actually called Black Cherry Swirl Fudge, and I changed two items from the original recipe:

2 1/2 cups sugar
2/3 cup evaporated milk (small can)
1/2 cup butter or margarine (1 cube)
1 package (10 or 12 oz) white or vanilla baking chips
1 jar (7 ounces) marshmallow creme
2 envelopes unsweetened black cherry Kool Aid (I used lemon Kool aid instead)

Line a 13x9x2 inch pan with foil and grease the foil with butter, (I used pam instead), set aside. In a heavy sauce pan combine the sugar, evaporated milk and butter. Bring to a boil over medium heat, stirring constantly. Cook and stir for 4 minutes.
Remove from heat; stir in vanilla chips and marshmallow cream. The vanilla chips did not melt very well every time I used them so I stirred in the vanilla chips while still on the heat and when melted I turned off stove and stirred in the marshmallow creme. Next they want you to put a cup aside and then stir in the Kool Aid to the remaining fudge and then swirl the two together so you have ribbons of white and color. I just stirred the Kool Aid into all fudge and the poured it into the pan to cool. I first made this last Christmas and it was very lemony, and while I like lemony most people said it was too much lemon, so this batch only had 1 package lemon Kool Aid, and that is still very good. What other Kool Aid flavors would make good fudge?
