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:'.

[Q]: CONTEXT: Vegetables don't ripen. Carrots, potatoes, leafy greens, etc...They will get bigger of course and some veggies will get more bitter or woody with age. Greens will get bitter.Generally speaking veggies are better young. Carrots are particularly sweet and tender when young. Potatoes are also perfectly fine at any size.The possible exceptions would be the fruits that are labelled vegetables for cooking purposes like some squashes and tomatoes. These do need to be ripe and whether they can be ripened after picking will depend on the plant. <sep> Q: Do vegetables ripen like fruit? A: Vegetables don't ripen Q: Is the growing of a vegetable different from a fruit's? A: The possible exceptions would be the fruits that are labelled vegetables for cooking purposes like some squashes and tomatoes <sep> FOLLOWUP_Q: I could pick a carrot up from the dirt whenever, and eat it, but I would never do that to a strawberry.
[A]: These do need to be ripe

[Q]: CONTEXT: A number of Chinese restaurants are happy to prepare it without pork or beef. I've seen it with pork (most common) or beef (sometimes).A vegetarian Chinese place that I occasionally visit uses a "vegetarian ham" along with some vegetables like peas to augment the custardy texture of the soft tofu. I like to add some ja tsai (zasai, depending on romanization preferences) pickles in there, though I'd guess that's not that common.Pork is not absolutely essential to the identity of the dish, but it's certainly the most likely version to be served. <sep> Q: What do you know about Ma Po Doufu? A: A number of Chinese restaurants are happy to prepare it without pork or beef. I've seen it with pork (most common) or beef (sometimes <sep> FOLLOWUP_Q: Is pork a necessary ingredient for it?
[A]: Pork is not absolutely essential to the identity of the dish, but it's certainly the most likely version to be served

[Q]: 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?
