Given a paragraph about cooking, and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.

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: What can you substitute for wine when making homemade salami? A: The solution here is to look for another recipe, one which is safe but does not contain wine  Q: Most of the recipes I found use wine. Would citric acid work as a replacement? A: Substitution in preserved foods are generally considered unsafe  <sep> FOLLOWUP_Q: So is the wine used as a preservative?

A: Yes

Q: CONTEXT: Rendered pork fatâmanteca de cerdoâis our preferred cooking fat throughout this book. Lard has a relatively high smoke point so it is ideal for frying, and it provides a richness, dimension, and distinctly Mexican flavor that you just can't replicate with using other fats...Vegetable oil is a fine substituteHowever specific recipes may really need lard: Note that the flaky texture and slight richness that make flour tortillas so compelling are derived from lard. I've found that vegetable shortening is a poor substitute here...Source: Alex Stupak and Jordana Rothman. "Tacos: Recipes and Provocations".  <sep>  Q: Why use lard in tortilla dough? A: the flaky texture and slight richness that make flour tortillas so compelling are derived from lard  <sep> FOLLOWUP_Q: why does the lard cause flaky texture

A: No

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:
Yes
