it will take 20 30 minutes to roast the chestnuts when cooked the shells will burst open and the chestnut will be golden brown the tricky part is actually knowing when they are done if you over cook or under cook them they will get hard and the inner skin will be very difficult to removehen spread them on a cookie sheet flat side down you can also sprinkle with sea salt at this point roast in a preheated 425 degree oven at the lowest rack position for 20 30 minutes i turn them over after 10 minutes and then check at 20 mins to see if any are done
Print. Braising is a process of slow cooking tougher cuts of meat in liquid in order to add flavor and to moisten and tenderize the meat. This technique is also known as pot-roasting.
Things to remember: 1  How long it takes for meat to get tender in a braise or slow cook method depends on the size of the cut, thickness of the cut, and the amount of collagen in it. Working cuts like chuck, rump, neck, shin, etc have lots of collagen and need a longer slow cook to break it all down. They also have more flavor.
