Kooky Key Lime Fudge

Ingredients

1/4 cup butter
2 1/2 cups granulated sugar
2/3 cup evaporated milk (or small 5 ounce can)
10 to 12 ounces white chips
6 or 7 ounces Marshmallow Creme or Marshmallow Fluff (may substitute 2 cups mini marshmallows)
1/3 cup Key lime juice
1/2 cup almonds or macadamia nuts, coarsely chopped
1/4 teaspoon rum extract
1 teaspoon lemon extract

Line a 9 inch square pan with aluminum foil and set aside.
Place white chips, extracts and nuts into Pyrex glass dish (or a 3 quart saucepan) and set aside.
Set butter aside to warm.
Heat milk at medium setting until warm then add sugar. Bring to a rolling boil (medium-high) while stirring constantly with a hand mixer (or wooden spoon).
Add Marshmallow Creme and butter and mix until creamy.
Add Key lime juice. Bring back to a boil for 5 full minutes (start timing once the boil resumes). The mixture will start to turn a little brown during the boil. If you get brown flakes in the mixture, then turn down the heat a little (e.g. down to medium from medium-high) and continue to stir.
Remove from heat and pour hot mixture over chips without scraping the sides of the hot saucepan. Mix until chips are melted then mix in nuts.
Pour into the prepared pan.
Cool at room temperature.
Remove from pan, remove foil and cut into squares.

Key Lime juice is acidic and will cause the milk to curl. While uncosmetic, it should not affect the fudge's ability to set.
