So I found a recipe for "twinkie" filling on here and I am wondering if I can add some preserves to it for a little more flavor without making it too runny? Here is the recipe:

2 tsp very hot water
Rounded 1/4 tsp salt
2 cups marshmallow creme (7oz jar)
1/2 cup shortening
1/3 cup powdered sugar
1/2 tsp vanilla
