Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

[EX Q]: CONTEXT: Both will do the job of greasing a pan but there are some differences. One of the big differences is that butter will add a very desirable flavor to whatever you are cookingâwhich especially complements sweet baked goods.Shortening is pure fat whereas butter is only about 80% fat by weight. Butter may bring additional flavor to your recipe (even by greasing the pan) but it also adds some water which may not be wanted.One final difference is that butter burns/browns more easily than shortening.  <sep>  Q: What's the difference between greasing a pan with butter vs. with shortening? A: Both will do the job of greasing a pan but there are some differences. One of the big differences is that butter will add a very desirable flavor to whatever you are cookin  <sep> FOLLOWUP_Q: What's the difference between butter and shortening?
[EX A]: Shortening is pure fat whereas butter is only about 80% fat by weight. Butter may bring additional flavor to your recipe (even by greasing the pan) but it also adds some water which may not be wanted

[EX Q]: CONTEXT: Caffeine is bitter, tea isn't too bitter because as you mentioned it's only got 40mg of caffeine. If you then triple the amount in there it's going to taste that way. Try adding 3 tea bags to your cup and I'm certain it'll taste just as bitter.Energy drinks have copious amounts of sweeteners added hence why they don't taste like caffeine. If you are hell bent on more caffeine without the associated bitterness but not adding sugar maybe a sweetener like stevia would be the way forward...  <sep>  Q: Why does caffeine taste bitter when added to tea? A: Caffeine is bitter  <sep> FOLLOWUP_Q: Why doesn't caffeine that is already in the tea or in an energy drink taste bitter?
[EX A]: Energy drinks have copious amounts of sweeteners added hence why they don't taste like caffeine

[EX Q]: CONTEXT: Substitution in preserved foods are generally considered unsafe. Food chemistry is a complicated affair, and cooking is inherently imprecise. Sure, you can find a way to reduce the pH to that of the original recipe. But a salami is a fermented food. Your pH might be the same, but other things will change, for example the composition of the available sugars, and you can catch a different strain of bacteria. Safe preservation recipes have either been extensively tested in a lab, or used for centuries. Making a small change can destroy the delicate balance which leads to a tasty, safe food. The solution here is to look for another recipe, one which is safe but does not contain wine. For something as risky as cured meat, I'd suggest not getting some random recipe off the Internet, but choosing from a book, or maybe from the blog of a known, respectable author. This way, you get both good taste and safety, things which are hit-and-miss when making your own substitutions.  <sep>  Q: Wine substitutions for homemade salami A: Substitution in preserved foods are generally considered unsafe  <sep> FOLLOWUP_Q: what would you suggest I use?
