Zimmermann Telegram rate. Usage: The Zimmermann Telegram was not looked upon too benignly by America-no one really knows why America entered WWI in April 1917, but the Zimmermann Telegram certainly didn't help. (Forget the sinking of the Lusitania, 23 months earlier.).
Cooking on HIGH Cooking on HIGH for one hour is equivalent to 2 to 2-1/2 hours of cooking on LOW. The HIGH setting of a slow cooker ranges in temperature from 300-325 F. The slow cooker becomes a soup kettle as liquids boil and evaporate at this temperature.
35-45 minutes 3 â 4 hours on High or 6 â 10 hours on Low. 50 minutes â 3 hours 4 â 6 hours on High or 8 â 18 hours on Low. We sometimes have callers concerned about the safety of their slow cookers. To determine if a slow cooker will heat food to a safe temperature, fill the cooker with 2 quarts of water. Heat on Low for 8 hours or the desired cooking time. Check the water temperature with an accurate thermometer (quickly because the temperature drops 10 to 15 degrees when the lid is removed).
