Given the task definition and input, reply with output. Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

CONTEXT: Are you absolutely certain that the "grittiness" is caused by the cheese not melting, and not because the sauce is curdling? If you cook it too long or too fast, that is what will happen.If you must use the Kraft stuff (personally, I think it has no flavour compared to real Reggiano), try melting the cheese on low heat in a very small amount of cream first, before you add it to the main sauce pan. If it's still gritty, either it's curdling or you need to use a better cheese.  <sep>  Q: How can I make cheap, smooth homemade Alfredo sauce? A: try melting the cheese on low heat in a very small amount of cream first, before you add it to the main sauce pan 

Is that with the pre-shredded cheese?
