[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 
[A]: Is pork a necessary ingredient for it?


[Q]: CONTEXT: There are many variables here that may or may not caused OP's problem.The Pan sounds as it might not have been hot enough. How hot was quite hot, how long could you hover your hand above the pan? Did you notice any change to the oil once you added it to the pan, did it streak, did it start to smoke?[Personally I tend to oil the meat before placing into the pan.]I think the main flaw is the frying for a minute on each side, at the temperature you had, that cooking time was too low. Maybe 2-4 minutes on each side. A medium should have a lot more heat penetrate the edges and allow that heat to transfer and cook the steak off the heat.That's an acceptable blue/rare steak though.  <sep>  Q: I have trouble cooking a steak 'medium', and to be honest, cooking it at all. My steak didn't turn out. What happened to my steak? A: There are many variables here that may or may not caused OP's problem.The Pan sounds as it might not have been hot enough 
[A]: Well, I heated a metal pan and added some oil when it was already quite hot put in the meat, It was 'glued' to the pan slightly - not hot enough?


[Q]: CONTEXT: Modern non-stick pans should not have problems with coatings flaking off. Spend $50 on a non-stick pan and it will last you for a very long time. Coatings on good pans should hold up to any non-metallic utensils. Very expensive pans suggest that you can hit them with a hammer and not hurt the surface.  <sep>  Q: What should I look for when choosing egg cookware? A: Modern non-stick pans 
[A]:
Do you have any alternatives to non-stick/Teflon?
