GRAMMIE AND GRAMPY'S -- PENUCHE FUDGE

• 
  
• 
• 
  
• Vegetable oil cooking spray
• 1 can (5 ounces) evaporated milk
• 1 1/2 cups packed light-brown sugar
• 5 ounces (1 1/4 sticks) unsalted butter
• 1/4 teaspoon salt
• 1/2 cup confectioners' sugar
• 1 teaspoon pure vanilla extract
• 3 ounces toasted walnuts, chopped (1 cup) (optional)
• DIRECTIONS:

1. Coat a 5-by-10-inch loaf pan with cooking spray (I don't think they used this!) Line with plastic wrap leaving a 2-inch overhang on 2 sides.
2. Bring evaporated milk, brown sugar, butter, and salt to a boil in a medium saucepan, STIRRING constantly. Reduce heat to medium-low, and simmer, stirring frequently, until mixture registers 236 degrees on a candy thermometer, about 25 minutes.
3. Transfer to a mixer bowl, and beat in confectioners' sugar on low speed. Scrape down sides of bowl as needed. Increase speed to medium, and beat until mixture is thickened and smooth, 2 to 4 minutes. Reduce speed to low, and add vanilla and walnuts.
4. Spread mixture in pan, smoothing top. Refrigerate, uncovered, until firm, about 25 minutes. Un-mold fudge using plastic overhang, and discard plastic. 
5. Cut into 18 pieces. (all that work for 18 pieces that Mike would eat 3/4 of!!)
