Prime rib in electric roaster
Larry
12/17/07 		I am cooking a 7 bone 15 pound prime rib roast. Can this be done in a electic roaster. The reciepe calls for 220 degrees and kosher salt all over the meat. If it can be done will it cook faster than a regular oven. Also with all that salt on the meat which is removed before serving, can you still use the juice to make ajus, or is there a receipe for ajus you would recommend. Thanks for your help

Yes you can use the roaster, I don't recommed it for most prime rib, but the salt crusted recipe will do fine. Yes it does seem to cook a bit faster- the best way to get perfect doneness, is to insert an oven thermometer before packing on the salt.

Definitely DO preheat the roaster for at least 20 minutes.

Yes the juices are too salty for au jus. I don't recommend any brand of au jus, here is the recipe I like (funny, I just got this out yesterday!)
"AU JUS" JUICE
Au-jus for Beef Dip Sandwiches and Meat sauce

8 pounds beef neck bones
4 large (2 1/2 pounds) onions, cut into large pieces
4 scrub rinsed, large carrots, cut into large pieces
1/2 large head of celery, including leaves, cut in chunks
1 can (6 ounces) tomato paste
1/2 teaspoon thyme leaves
1 tablespoon dried parsley flakes OR 1/2 bunch fresh parsley with stems, chopped
1 whole head of garlic cloves, rinsed and left in skins, split crosswise
1 teaspoon whole black peppercorns
1 tablespoon coarse rock salt

In a large stock pot (deep narrow pot), add enough water to cover ingredients. Bring to full boil, then immediately reduce heat to simmer. Cover and cook for several hours adding small amounts water if needed but try to maintain a concentrated level for more flavor. Strain.

*Save any cooked meat from neck bones, shred to use in other dishes, very good when added to spaghetti sauces and Mexican dishes. This meat also can be frozen for use another time.

Freeze any leftover stock in ice cube trays for another day to add flavor to brown gravies and homemade soups. Thicken it with corn starch or flour.

I'd imagine the roast cooks faster because there is a smaller area to heat and can the heat can be more consistant. I'd bet the ceramic walls help too.

I really want to try a slow roast as well. I am using a digital thermometer to make sure I cook to the right temperature but. Does anyone know what it will take to get a roast done at this temp? 30 min per lb...45?

12/22/07 		Did you look at the time tables on the roasting beef page in holiday cooking at the top of the Big Pots section?

12/22/07 		By the way, I would start it at 300 for the first hour, before turning down. Then allow 45- 60 minutes per pound at 220.

12/22/07 		does a 5 lb prime rib roast cook faster than a 15
we have a 15 lb prime rib rost and a 5 lb. rib roast if we cook them together will the 15 lb. roast get done before the 15 lb roast.

12/22/07 		???The 5 pound will cook much faster. If you want them to be done at the same time, cook them separately, or calculate the cooking time for the small one and only put it in that amount before the end time.

Both these need to stand before slicing- 15-30 minutes.
