Kelly's Ham Jell-O Salad

Step 1
Dissolve lemon gelatin in boiling water in a large bowl. Pour reserved pineapple juice and white wine vinegar into a measuring cup; add enough cold water to measure 1 cup. Stir water-juice mixture into gelatin mixture; refrigerate until cold and beginning to set, about 30 minutes.

Step 2
Stir mayonnaise and spicy brown mustard together in a bowl; whisk mayonnaise mixture into cooled lemon gelatin mixture until smooth. Gently fold cabbage, ham, celery, and reserved pineapple into gelatin. Transfer mixture into a ring-shaped gelatin mold.

Step 3
Chill in the refrigerator until firmly set, about 4 hours.

Step 4
To serve, dip the gelatin mold into hot water to loosen the sides; place a plate on top of the mold, invert, and gently lift the mold from salad.
