White and red wine serve as substitutes for cream sherry in cooking. Apple cider vinegar and sweet vermouth also work as substitutes. Cream sherry is a sweetened version of sherry and is not actually creamy, so all of these substitutions are suitable.
When using white wine, it is best to use more than the recipe specifies. When using red wine, it is best to use a wine that has a bit of sweetness to it. Apple cider vinegar can be used in recipes that don't need alcohol for taste. When using sweet vermouth, it is best to use about half of what the recipe calls for, or the vermouth may overpower the dish.
