The woman youre about to meet says if its just burgers and dogs on your menu its time to expand those taste buds. Tonight, one american chefs taking us on a succulent south american adventure that involves less easy to love parts, from nose to tail. She says theyre not only delicious, they can be healthy too. Look at how beautiful it is, so many cows. Reporter three hours outside of monte vedeo, uruguay, were on the hunt for the worlds best barbecue. Uruguay is very flat. Thats part of why its so easy to raise beef here. Reporter the american butcher, rancher, and restaurateur is heading into goucho country, the land of the famous south american cowboys. Cooking this for two and a half hours, three hours over this low, slow eat. Uruguay is where i come for inspiration. Everything is rough and unfinished. Im going to hang out at the grill and eat the whole thing. Reporter anja was once a vegetarian. Then i had a radical experience. I went from low fat, no fat, 90s lifestyle to moving to southern italy and eating a ton of pork fat and lost weight and got healthier. Reporter now shes all about the meat. Not just any meat. Raw meat. Fatty meat. Shes making it her business to get the rest of us to eat like she does. That was delicious. Right here. Uruguay is the land of meat. This is where it all starts. So this is our santa monica butcher shop. Reporter back home in california shes building a meat empire with a string of butcher shops and restaurants. Bell campo meats. Everything from guinea fowl and quail and squaub to classic beef and pork. Reporter and shes assembled an army of true believers who work there. I grew up on fish sticks and hot dogs folded into mac and cheese. Like a lot of people. I didnt know what food could taste like. I had an eyeball in crete. And that was pretty adventuresome. It was a big goat roast. Reporter they dont insist you eat eyeballs but they say meat is more about chicken breasts and lean steaks. This is all fat from the big from the fatback. And its insanely delicious. The craziest yummy taste that you didnt know existed. Been eating fat since the beginning of time. Thats a little lamb. Very little. I chose it because its tender. Reporter anja scours the world in search of new recipes. Id love to go to northern scotland and do taste mutton with fur on traditionalstyle butchery. Reporter if this sounds unappetizing, according to anja its because weve lost touch with the way we should be cooking. The philosophy is a simple oldfashioned way of eating. Its the opposite of fast. Instead of grabbing something you can eat in your car, its cooking at home. Reporter the way people cooked for centuries. Which brings us back to those cowboys in the mountains of uruguay. These guys have what a lot of people say is the best grilling technique in the world. Its going to be very very tender. Essentially a slow smoke. Its called asado. They cook all the meat they go very slowly, and its really an allday affair. Now were going to make blood sausage. With blood and the key is to have good blood. It needs to be very liquid. If the blood is coagulated when you make sausage, as you chew it theres kurds of blood in it. It tastes bloodier. A little nutmeg. Mm, smells like christmas. Reporter they cook up every last bit. Asado is all about the slow. Here we have a number of cuts that are being cooked over a pretty low, slow fire. These are little ribs over essentially a low temperature for hours and hours. The meat gets quite tender. And this lovely fat renders out and bathes that meat in liquid fat. It stays really tender and moist. Reporter that slow cooking is what anja says enables the gauchos to get a tasty meal out of cuts the rest of us would throw away. A lot of these cuts in the american tradition, wed be cooking them with moisture braising them. Theyre tough cuts. Top round, cuts like that. With this very low heat theyre essentially doing slow cooking which makes the flavors really come out, and almost smokes this meat. Reporter since most of us dont have 12 hours to make dinner, anjas latest plan is to package these dishes and sell them to you for cooking at home. I was really impressed by the fresh intestines. Reporter shell bring the recipe back to santa monica where her chef told us get this raw lamb and pure lard on toast are already big sellers. Seeing that fatty intestine, how it grave that great crust, is amazing. That we can mess around with. It looks spectacular to sell it fresh because its hairy and covered in fat. I think people will freak out about that. Reporter yes, she knows its not for everyone. Yet. But she has a strategy. Deliciousness wins. And conquer the heart forthrough the stomach. Make the change delicious. So what delicious things will you be grilling up this weekend . I for one will be marinading. Head to our Nightline Facebook page and share your barbecue secrets.
