Question: CONTEXT: Allowing dough to rise twice results in a finer gluten structure than allowing it to rise once. It results in a smaller crumb and prevents huge gaping airholes in your bread. The reason that you have to let it re-rise is that you just pushed all the air out with the kneading you did developing that gluten structure.  <sep>  Q: Why let dough rise twice? A: Allowing dough to rise twice results in a finer gluten structure than allowing it to rise once 

Answer: When making bread, why do recipes say to let the dough rise twice instead of once?###How does a firmer gluten texture help?


Question: CONTEXT: First, remove some, but not all, of the end. Make sure to leave a little of the root intact, as this will make the next steps easier. Peel the onion and discard the peel.Stand your onion on one of the now-flat ends. Chop in half with your chef's knife.Lay a single half on the flat end. Working from root to cut end, make several cuts at dice width that cut almost to the root end, but leave a little bit still attached.Working perpendicular to your last set of cuts, make another set of cuts at dice width. This will leave you with cut pieces. When you get to the portion with the root, discard it.Repeat for your other onion half.During cooking, the layers should flake apart leaving dice sized pieces.  <sep>  Q: What is the best method of dicing an onion? A: First, remove some, but not all, of the end 

Answer: Which end?


Question: CONTEXT: Absolutely! Metal skewers contribute to cooking the meat from the center as they pick up heat from the exposed parts and conduct it throughout.It is a good idea not to crowd your metal skewers with pieces of food to promote this. Not crowding the skewers also exposes more surface area for the food to caramelize. Doing this on a wooden skewer runs the risk of burning the skewers and losing food into the grill.  <sep>  Q: Do metal skewers make a considerable different cooking time than wooden? A: Metal skewers contribute to cooking the meat from the center as they pick up heat from the exposed parts and conduct it throughout 

Answer:
So, metal skewers are definitely better than wooden?
