[Q]: CONTEXT: They're good pretty much forever. There is not enough available water for things to grow in there. Mind you, the more aromatic and subtle parts of the flavor will dissipate over time. The sugar absorbs water, giving the combination a very low water activity, meaning there's little water available for microorganisms to use in growth. As long as your flavoring pieces are small and well mixed with sugar they will not spoil.  <sep>  Q: How long is sugar (mixed with minor ingredients) good for? A: They're good pretty much forever. There is not enough available water for things to grow in there  Q: I mixed them over a year ago, would it still be good? A: As long as your flavoring pieces are small and well mixed with sugar they will not spoil  Q: Some I mixed with lemon/orange zest, will that pose a problem? A: As long as your flavoring pieces are small and well mixed with sugar they will not spoil  <sep> FOLLOWUP_Q: Are you sure it will be safe to use?
[A]: Yes


[Q]: CONTEXT: There's always the delight of botulism, which thrives in the anaerobic environment provided by vacuum packing. Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish. With this in mind, I would not expect vacuum packing to extend the life of a fish much. It will reduce freezer burn though!  <sep>  Q: Do you think it makes a difference what type of fish it is? A: Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish  <sep> FOLLOWUP_Q: Is the vacuum seal an anaerobic environment?
[A]: Yes


[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  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: Do you know if there is a vegetarian alternative to it? A: 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  Q: That's nice to know. What version do you prefer? A: I like to add some ja tsai (zasai, depending on romanization preferences) pickles in there, though I'd guess that's not that common  Q: Does that make it more tastier? A: I like  <sep> FOLLOWUP_Q: What is the origin of this dish, do you know?
