Instructions
Trim excess fat from roast. In a large zip to lock plastic bag, add onion, lemon, spices and salt and sugar. Pour in vinegar and water. Add roast. Refrigerate for two days, turning meat approximately every 12 hours during marinating time.
Place meat in a crock pot. Strain the marinade and add 1 cup of liquid to the meat in the crock pot, reserve the rest in the refrigerator to thin gravy if needed. Cover crock pot and cook on low 6 to 8 hours.
Remove meat to a serving platter. Turn crock pot control to high. Stir in the flour mixture and gingersnaps. Cover and cook on high for 15 minutes, thinning with reserved marinade or water as needed.
