Fresh grapes, cream cheese, sour cream, and nuts are naturally gluten-free making this recipe an option, for those following a gluten-free diet. However it's important to select the brands and products you use. Make sure that your cream cheese, cream and vanilla extract are clearly labeled as gluten-free. When it comes to nuts there can be a risk of cross-contamination. To be safe choose pecans that have been certified gluten-free to ensure they haven't been in contact with any gluten-containing products, during processing.
