This is a favorite of my mom’s. Grandma Yearwood served this at the first meal my mom had with the Yearwood family after she met my dad. Daddy was an only child, so it must have been pretty intimidating to sit with just Mrs. Elizabeth and Mr. Bo for dinner! The fact that my mom is a really good cook, too, was an icebreaker for them, and I think it was the first thing they liked about her—besides the fact that Daddy was obviously crazy about her!
In a medium bowl, stir the gelatin into the boiling water. When the gelatin is completely dissolved, stir in the evaporated milk, pineapple, lemon juice, cottage cheese, celery, mayonnaise, and pecans. Pour the mixture into a 1½-quart square clear glass dish. Chill overnight, or until firm. Cut the chilled salad into squares and serve on lettuce leaves. Garnish with twisted lime slices.
