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 whole idea of using a cedar plank is to char the heck out of the bottom and produce lots of smoke and flavor. My roughly 1/4 inch planks are usually charred pretty well and I simply couldn't see using them a second time. At times, it seems that 1/8 inch or more of the bottom is gone.If you find a good source for your planks, they should be pretty inexpensive so why push it? I found one of the best sources to be my supermarket right next to the fish counter. $3 - $4 / plank. Seems like a small price to pay when you are grilling a $30 piece of salmon on top of it.  <sep>  Q: Are reusable or disposable cedar planks better? A: The whole idea of using a cedar plank is to char the heck out of the bottom and produce lots of smoke and flavor 
Are the reusable ones good?

CONTEXT: The raspberries should work if you strain them thoroughly and fold them in very carefully so they don't break apart. Adding the liquid to the cheesecake will noticeably alter the texture, probably making it mushy; note that there aren't any water based ingredients in the recipe which you could substitute raspberry syrup for. I wouldn't recommend it. If you wanted to add raspberry flavor to a cheesecake, your best bet would be a raspberry pastry flavoring oil. If you didn't want to waste that liquid (and why would you,) just drizzle it on top of each slice as you serve it.  <sep>  Q: Can i substitute in frozen berries when my cheesecake recipe calls for fresh ones? A: The raspberries should work if you strain them thoroughly and fold them in very carefully so they don't break apart  Q: What if I also wanted to add berry juice to add more berry flavor (and a nice color) would that work? A: I wouldn't recommend it. If you wanted to add raspberry flavor to a cheesecake, your best bet would be a raspberry pastry flavoring oil 
What would be the best method to use in order to strain the frozen berries thoroughly?

CONTEXT: Here's a quote from the short section "Stir-Fry" in the Gargantuan work "Modernist Cuisine": ...a wok burner can deliver up to [...] 200,000 BTU/h of thermal power. [...] By comparison, Western-style professional gas burners deliver [...] 15,000-30,000 BTU/h), and domestic gas burners [...] 6,000-14,000 BTU/h)...So for professional stir-fry ("bao" in thai - I think), the hotter the better. But there's also non-professional "chow" stir-fry, which is, in "Modernist Cuisine"s words, more like a "covered saute". You don't do the asian stir-fry because the flame is just too small, so you cook the fresh foods in their juices, stop while they're still crisp, and know that the world holds compassion also for guys with stoves like ours.  <sep>  Q: What gas output required for home stir frying? A: Western-style professional gas burners deliver [...] 15,000-30,000 BTU/h), and domestic gas burners [...] 6,000-14,000 BTU/h  Q: what is best for stir frys? A: So for professional stir-fry ("bao" in thai - I think), the hotter the better 

at what temperature?
