Good old beef
Good question! If the stock is a light golden color, it's ok. If the stock is a dark yellow or brown, don't use. This would be if you are using turkey or chicken broth. If you are working with beef stock, a tan color is ok. If it is a light brown, that's ok as well. If the beef broth is dark brown or a very oddly colored black don't use. Beef broth is darker then turkey or chicken stock.
"Color of BeefBeef muscle meat not exposed to oxygen (in vacuum packaging, for example) is a burgundy or purplish color. After exposure to the air for 15 minutes or so, the myoglobin receives oxygen and the meat turns bright, cherry red.After beef has been refrigerated about 5 days, it may turn brown due to chemical changes in the myoglobin. Beef that has turned brown during extended storage may be spoiled, have an off-odor, and be tacky to the touch."from http://www.fsis.usda.gov/Factsheets/Beef_from_Farm_to_Table/index.asp
The Food TV network website is credible for recipes. I like the Beef Jerky Recipe from Alton Brown. Its is a very detailed recipe. But it is worth time.
For the small-time producer, yes, but as a conventional beef animal, no definitely not. Brown Swiss are bred to be dairy cattle, or to produce milk, not to produce beef. However, that's not to say that they cannot be raised as beefers: Brown Swiss steers tend to fatten up and finish better than Jerseys, for one, and even Holsteins. But they're still dairy cattle regardless.
Good ground beef makes a good hamburger.

Beef is a very good meat to mix with pasta. There are many delicious recipes that use bite-size beef chunks or ground beef.
If you are cooking beef a good combination is potatoes, beef, and onions. You should use the internet or a cook book for a good recipe. You should cook beef, potatoes and vegetables as they are a good combination.
