1 (6 ounce) can sliced pineapple, drained
1 (4 ounce) can pineapple juice
2 scoops vanilla flavored Jell-O mix
1 teaspoon lemon zest
1 teaspoon lemon juice
1 cup boiling water
4 fluid ounces lemon-lime flavored carbonated beverage
In a large bowl, mix pineapple juice and pineapple jelly. Pour into quart jars with pinking tip. Cover, and shake to coat. Refrigerate 1 hour. Refrigerate 1 week. Refrigerate remaining jelly; refrigerate for 4 hours.
Stir pineapple jelly into pineapple gelatin and stir gently to dissolve. Adjust to your taste. Refrigerate 8 hours or overnight, or until jelly is thickened. Refrigerate leftovers.
While jelly is chilling, pour boiling water into a large saucepan and mix thoroughly. Stir in lemon-lime soda. Bring to a simmer, and bring to a boil. Cover, and partially cover jelly with plastic wrap. Remove from heat. Stir jelly slowly in 1 cup of pineapple juice to 1 cup of pineapple gelatin, stirring constantly. Pour into jars to 1/2 inch thick.
