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: What I've done in the past is mist some water on both sides of the bread slices, then put them in the microwave for 10-15 seconds (alternatively, an oven set at 300F/150C for 5-10 minutes will do it too).Experiment with the amount of water (but keep it low) and cooking times. You should get much softer (and warm) bread slices out of it. <sep> Q: How can I soften the texture of storebought whole-grain bread? A: What I've done in the past is mist some water on both sides of the bread slices, then put them in the microwave for 10-15 seconds
Will the bread's shelflife be diminished after spraying and microwaving it?

CONTEXT: Yes, you can freeze parmesan cheese. Even without freezing, Parmesan is very durable since the low water and high salt content prevents mould from growing. The younger varieties may be more prone to mould growth (having a higher water content), but I've kept ripe Parmesan (30-36 months) for at least a year in the fridge without problems (and it would probably have stayed good much longer). Just remember to keep it wrapped in paper, not in a sealed plastic container to prevent a buildup of condensation. <sep> Q: Can I freeze Parmesan? A: you can freeze parmesan cheese
How long can I keep it for?

CONTEXT: I always submerged mine in warm water and, bare handed, worked the cap until it came free. The water should dissolve the salt with the help of the mechanical action. That was with glass bottoms and metal tops. You should be able to brute force your full metal shaker with no ill effect as the metal will have a much higher shear strength than the salt that is binding it. <sep> Q: Any idea how to get a stuck lid off a salt shaker? A: I always submerged mine in warm water and, bare handed, worked the cap until it came free Q: How long do I leave it in the warm water? A: The water should dissolve the salt with the help of the mechanical action
So will all the salt inside dissolve or only where the lid is stuck?
