I was deeply in need of beef yesterday, so I figured I'd give the Not Your Mother's Slow Cooker Cookbook the old college try. Although, as I've mentioned below, I'm a little dubious of getting all gor-may and fancy with the Crock Pot, they did have a terrific brisket recipe.
Now I will digress and note that my mother is adamant that good old Jewish brisket should be flavored with onions and wine, and should not have a hint of sweetness. She makes all kinds of remarks whenever anyone serves a sweet and sour brisket when we're invited over for a holiday dinner elsewhere (after we leave, I should note, not in front of the hosts). I myself happen to love sweet and sour foods, so on this point (along with countless others) I buck the parental preferences.
This recipe struck the balance perfectly. The brisket is well seasoned with salt, pepper, and paprika, then given a good sear on both sides and set aside. In the same pan, you then fry up a good amount of slivered onions. The brisket is slathered with a mix of tomato paste, garlic, brown sugar, dry mustard, cider vinegar, and worcestershire sauce, and sandwiched between layers of the onions in the Crock Pot, then cooked on low for 5 hours. The result is oniony, tangy, and flavorful, with a surprising amount of gravy, considering no significant liquid is used. You could add more sugar and raisins to make it sweeter, or leave out the sugar altogether, though I really enjoyed it as is. And look forward to eating a sandwich of the leftovers tonight, on a Kaiser roll I bought for this exact purpose. The beauty part: will not have to share with mom.
