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: Breads get their structure from glutens--a type of protein formed by the combination of glutenin with gliaten. Kneading and resting the dough helps the formation of glutens--I assume by shifting glutenin and gliatin molecules around, this increases the odds of bindings occurring.Oils can bind to glutenin and gliatin and inhibit these reactions, so fats--oils and butter--definitely play a role in the texture control.It prevents the dough from getting too elastic, which controls texture. This elasticity change would also change the maximum air bubble size. Altering resting times and yeast quantity also change these, but trading off for a different flavor. Oil may play other roles, but these are what I recall reading about off the top of my head. Yes, it does contribute to flavor as well.  <sep>  Q: What is the purpose of oil or butter in bread? A: Oils can bind to glutenin and gliatin and inhibit these reactions, so fats--oils and butter--definitely play a role in the texture control  Q: what is the purpose of adding oil or butter to the dough? A: It prevents the dough from getting too elastic, which controls texture  <sep> FOLLOWUP_Q: Is there some background chemical reasons for adding it.

A: Yes

Q: CONTEXT: Tender means soft and not brown. Sour cream will curdle if the fat content is not high enough (if it is high, it is called creme fraiche, techniquelly) and if you cook it down too much on too hot heat. Next time, use higher fat content and cook on lower heat. Cream, sour cream and creme freche are not really substitutions, not techniquelly and not taste-wise.Mixing butter and sour cream will work, if you take your time and boil down with hardly any or no bubbles.  <sep>  Q: My sauce made from butter and cream is flaking and curdling, do you know what could be wrong? A: Sour cream will curdle if the fat content is not high enough  <sep> FOLLOWUP_Q: Can it curdle if the heat is too high?

A: Yes

Q: CONTEXT: I'd suggest skinless bone-in chicken thighs, as they have plenty of fat and collagen to keep them moist and tasty. I've cooked them in French-style wine-based stews, not to mention cacciatorre, for 2-3 hours before now and they just fall off the bone. It is virtually impossible to overcook them, unless you boil them mercilessly for hours. Just get a nice gentle simmer going - not only will this make the meat tender, but it will improve the flavour of the tomato sauce as well.Do not use chicken breast - it is far too lean.  <sep>  Q: what is a Substitution for beef (veal) in a stew? A: I'd suggest skinless bone-in chicken thighs, as they have plenty of fat and collagen to keep them moist and tasty  Q: will it takes longer to cook the stew? A: I've cooked them in French-style wine-based stews, not to mention cacciatorre, for 2-3 hours before now and they just fall off the bone  Q: how long do I cook the chicken? A: It is virtually impossible to overcook them, unless you boil them mercilessly for hours. Just get a nice gentle simmer going  Q: what is a good tip you can give me for my stew? A: Do not use chicken breast - it is far too lean  <sep> FOLLOWUP_Q: any pointers on any other meats?

A:
No
