Fluffy Pineapple-Pear Salad

Directions

1. Drain pineapple, reserving juice in a 1-cup measuring cup. Add enough water to measure 1 cup; set aside. Combine pineapple and pears in an 8-in. square dish; cover and refrigerate.
2. In a small saucepan, combine the sugar, flour and salt. Stir in the pineapple juice mixture until smooth. Cook and stir over medium-high heat until thickened and bubbly. Reduce heat; cook and stir 2 minutes longer.
3. Remove from the heat. Stir a small amount of hot mixture into egg; return all to the pan, stirring constantly. Bring to a gentle boil; cook and stir for 2 minutes.
4. Remove from the heat. Gently stir in vinegar. Cool to room temperature without stirring. Fold in whipped topping. Spread over fruit. Cover and refrigerate for 1 hour or until chilled.
