Given a paragraph about cooking, and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.
Q: CONTEXT: You don't need to defrost it, you can add cold roux directly to a boiling liquid. To avoid lumps from the roux, most cooks suggest you either add cold roux to a hot sauce, or cold liquid to hot roux. If you heat the roux gradually with the liquid you may get lumps, and don't get a good impression of how much thickening is going on until it heats fully.  <sep>  Q: I like preparing a large quantity of Roux and pouring them in ice trays to keep them in the freezer. How would I defrost them?
A: 
Yes
