Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

Ex Input:
CONTEXT: In a cookbook that old, the sour cream referenced is probably a home-fermented variety, used as a preservation method in the days before widespread home refrigeration. You can still do this with the appropriate bacterial cultures, but most of us now buy our sour cream at the store instead. That product is similar, but made in much larger batches with a highly standardized, refined bacterial culture, producing a product with a predictable sourness and texture. Home-cultured versions are more variable, but they use similar processes on a much smaller scale.Whether you want to call this the "same" is partly a linguistic distinction that depends on how much you want to consider the differences in scale and equipment between pre-refrigeration and modern methods.In contrast, the addition of something sour to cream is really a substitute, used when you don't have a proper sour cream available. A cook back in the 1890s could use the same substitution then as we might today. But the production of sour cream (and all sorts of fermented milk products, such as yogurt and kefir) is much older than that, and there would have been some variety of "traditional" sour cream available, though not universally or year-round in the days before mechanized food distribution systems.  <sep>  Q: Is sour cream in olde recipes the same as sour cream today? A: the sour cream referenced is probably a home-fermented variety, used as a preservation method in the days before widespread home refrigeration  <sep> FOLLOWUP_Q: How would I make a home-fermented variety of sour cream?

Ex Output:
You can still do this with the appropriate bacterial cultures, but most of us now buy our sour cream at the store instead


Ex Input:
CONTEXT: Both will do the job of greasing a pan but there are some differences. One of the big differences is that butter will add a very desirable flavor to whatever you are cookingâwhich especially complements sweet baked goods.Shortening is pure fat whereas butter is only about 80% fat by weight. Butter may bring additional flavor to your recipe (even by greasing the pan) but it also adds some water which may not be wanted.One final difference is that butter burns/browns more easily than shortening.  <sep>  Q: What's the difference between greasing a pan with butter vs. with shortening? A: Both will do the job of greasing a pan but there are some differences. One of the big differences is that butter will add a very desirable flavor to whatever you are cookin  <sep> FOLLOWUP_Q: What's the difference between butter and shortening?

Ex Output:

Ex Input:
CONTEXT: Well, you don't need to spend hundreds of dollars, but you might need to put in more elbow grease. You can get a hand-crank meat grinder for about $30 or so and a manual sausage stuffer for about the same. You could save on the grinder if you have a food processor or blender that can have its way with the meat.  <sep>  Q: How do you make homemade sausage without meat grinder/sausage stuffer? A: food processor or blender  Q: Which is better a food processor or blender? A: food processor  <sep> FOLLOWUP_Q: Why is a food processor better?
