Plugged in for 2 pounds of chuck - 3 servings, and it was awesome. I put it in at 9pm and turned it off at 8am. I put it straight in the refrigerator, and then pulled it out later in the evening for dinner. I reheated the entire contents of the crock pot on the stove top and it fell apart as it reheated... AMAZING I didn't have tarragon or chili powder. I added about 1/2 teaspoon of oregano, cumin, and crushed red pepper, and about 1 teaspoon of kosher salt. I doubled the amount of beer - I used Dos Equis. I backed off on the hot sauce - Louisiana Hot Sauce We ended up using this beef for tacos, but it looks like it would be amazing for just about any shredded beef application - sandwiches, enchiladas, or burritos.
