For a sweet dip for fruit try equal parts of softened cream cheese and marshmellow creme. Fruits really need to be patted dry with paper towels for the dip to cling well.
Don't forget chocolate. I used the bark that you melt to coat candies and decorate cookies. It is thinned with crisco and has to be kept warm in a fondue pot or slow cooker We used angel food cake chunks, pineapple, marshino cherries, bananas, marshmellows, etc.
Our favorite veggie dip is the powdered onion-muchroom soup mix mixed with sour cream. Any veggie is good. Brocolli, cauliflower, zuchini, cucumbers, carrots, celery, grape tomatoes.
