Frequently Asked Questions

What can I use instead of cream cheese?

If you want a lighter option, consider using ricotta cheese or a dairy-free cream cheese alternative. Both will provide a similar creamy texture. Adjust seasonings accordingly, as some alternatives may have different flavor profiles.
