WOT to know about this recipe: For this recipe, you can use cooking sherry or cream sherry — If you’re not familiar with cream sherry it is important to know there is no actual cream in cream sherry. Cream sherry is a base blend of Amontillado or Oloroso wine that has been topped with Pedro Ximenez, a sweeter wine. Cooking sherry can be purchased in the grocery store because it contains little to no alcohol. Cream sherry can be purchased at a liquor store or if your grocery store sells alcohol, it would be in the wine section. Either of these sherry products once opened do not need refrigeration and will keep for at least 12 months.
