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:'.

Q: CONTEXT: Anything can spoil eventually, refrigerated or not. Keeping something under a lid and refrigerated restricts the number of airborne colonizers that might get access to it, and the cold temperature means that even if they get there, they will grow much slower than at room temperature.For something to spoil, it needs to be colonized by bacteria or fungus spores, and it needs to contain some nourishment to support their growth, not too much chemicals that prevent their growth, and not too much competing life forms already present. So, things with a high concentration of salt or sugar tend to be unhospitable to bacteria and fungi growth, because they are hygroscopic (they draw the water out of cells). Extreme high or low pH (eg acidic) also retards growth. Think of things like ketchup, mustard, jelly with labels that say "refrigerate after opening" but most people ignore them. Alcohol is unfriendly if the concentration is too high, and of course natural fermented foods are already occupied by human-friendly bacteria.Ketchup is sealed in a bottle, usually with no fingers or utensils inserted into it, so it stays pretty sterile. It is also protected by being hygroscopic (due to high concentration of sugar and salt) and its acidity. Ketchup as a word and concept is descended from an Indonesian fish sauce, and has been around much longer than refrigeration. I think you can leave it out with no worries unless you see obvious mold growth. <sep> Q: Does ketchup belong in the fridge, or the cupboard? A: has been around much longer than refrigeration. I think you can leave it out with no worries unless you see obvious mold growth Q: What type of mold can grow on ketchup?

Q: CONTEXT: In short, using port as a substitute for red wine will not wreck the dish.Though the flavour is different (and richer) and will make your bolognese taste different as a result, the taste should not be bad. I frequently do this as I am not a red wine drinker, and port keeps far better in an open bottle. I would recommend using slightly less than when using red wine, but this is highly subjective. <sep> Q: Will swapping the red wine in my spaghetti bolognese with port wreck the dish? A: Though the flavour is different (and richer) and will make your bolognese taste different as a result, the taste should not be bad

A: What is the difference in taste between a port and the usual red wines that are used in bolognese?

Q: CONTEXT: Increasing the amount of yogurt and/or banana mash should work best, the former having a more noticeable difference. You might have to experiment to get the amount right, but I'd suggest starting with an additional 1/4 cup of yogurt or banana mash. You could try more date puree as well but that might make the muffins too thick. <sep> Q: How do you add moisture to gluten free, egg free muffins? A: Increasing the amount of yogurt and/or banana mash should work best

A:
What about increasing the amount of butter?
