Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

CONTEXT: The easiest way to tell if you've over stirred muffins, quick breads or cakes is the texture when it's baked.Correct, and it's all even. Over stirred, and you'll have a series of larger bubbles in the cake, called 'tunneling', where it looks like worms have burrowed their way through your cake or muffin.Stirring develops gluten, which is essential to trap in bubbles for most yeast breads, and to give it a little bit of chew -- but not something that you want in a typical quick bread. (muffins, cake, etc.)  <sep>  Q: Why does over-stirring the muffin mixture result in tough muffins? A: Stirring develops gluten, which is essential to trap in bubbles for most yeast breads, and to give it a little bit of chew -- but not something that you want in a typical quick bread 
In muffin recipes, the instructions often say to stir the mixture till "just combined", what exactly does this mean?

CONTEXT: Presumably you are experiencing rancidity, due to oxygen.While you have nitrogen flushed the bags at filling time, the bags are not impervious to oxygen diffusion.A different type of bag (an "oxygen barrier" bag material) or package (glass jar, or metal can) and, in addition, (based on other packaging I have seen) oxygen absorbing packets inside the bag may be required for long shelf life. Either alone would probably extend the shelf-life somewhat.  <sep>  Q: How do we keep our roasted cashews from smelling bad eventually? A: Presumably you are experiencing rancidity, due to oxygen  Q: So I should suck the air out of the packaging? A: A different type of bag (an "oxygen barrier" bag material) or package (glass jar, or metal can 
Should I use something other then polyproplene?

CONTEXT: What gives spices their flavors are the oils that they contain, along with any water soluble flavors that they might have. In a pressure cooker, your food will cook hot. What that means to your spices will vary as certain spices could grow more bitter or sweeter depending on the compounds inside them. Conventional wisdom says that pressure cooking concentrates the flavors, although that would seem to fly in the face of physics as you aren't reducing while pressure cooking, you are just heating steam at a higher atmosphere to transfer more heat to the food faster.As for texture, use the one that you like.  <sep>  Q: What the difference between cooking vegetable curries in a pressure cooker and a wok? A: Conventional wisdom says that pressure cooking concentrates the flavors  Q: Does that mean I will get a more flavorful vegetable currie in a pressure cooker? A: What that means to your spices will vary as certain spices could grow more bitter or sweeter depending on the compounds inside them 

How does a currie made in a Kadhai compare to ones made in a pressure cooker?
