Question: CONTEXT: Yes, it can go bad.It's pretty much the same as the way flour can go bad: the fats can go rancid. Grains are mostly starch, but they contain enough fat for rancidity to be a noticeable problem. There's a huge amount of variability in how long that takes, though. If it's airtight and kept in a cool, dark place, it'll last much longer than the best before date. But if it's been exposed to air, light, or heat, it can go pretty fast, perhaps even before the best before date.So, smell it. If you detect any unpleasant smells, you probably don't want to eat it. Even if you don't smell anything obvious, it could still be subtly rancid, so if you're planning on serving it to anyone, you might want to cook a small bit to test.  <sep>  Q: Does polenta go off'? A: it can go bad  Q: How can I tell if it's bad? A: smell it. If you detect any unpleasant smells, you probably don't want to eat it 

Answer: What if it doesn't have any odor?


Question: CONTEXT: The feeding/maintenance of your starter is the same regardless of flour. Remove and discard (or use elsewhere) half or more of starter. Add fresh flour and water in the desired proportions. Stir. As your starter matures, it becomes acidic. Too much acidity interferes with yeast activity in the bread making process. That is why you need to remove a portion of the "spent" starter each time you feed.  <sep>  Q: How do I add flour to sour culture ? A: Remove and discard (or use elsewhere) half or more of starter. Add fresh flour and water in the desired proportions 

Answer: What is the proportion I should add flour and water in ?


Question: CONTEXT: When I make a paella I never cover it, I find it keeps in too much moisture. My uncovered method is to put the fish in and cook for 10 minutes. If my mussels are small I will usually wait 2-3 minutes before putting them in, bu for "standard" mussels 10 minutes seems to work well. I use a low-medium heat on a large burner.  <sep>  Q: How long to cook seafood in paella? A: burner  Q: How long to cook mussels? A: If my mussels are small I will usually wait 2-3 minutes before putting them in, bu for "standard" mussels 10 minutes seems to work well. I use a low-medium heat on a large burner
