Sure to make your picnic a LOT more interesting or the Hempstead, TX Watermelon Festival! Here are three ways to achieve this dastardly deed. I prefer rum over vodka for this but champagne is nice too especially with the open and honest method. UPDATE: I tried this recently with Vanilla Vodka and OMG! It was FAB! BUT FIRST- Rinse the whole melon to remove any dirt or icky stuff that might be on the skin- seen or unseen! ewwww!!!! I never used to do this part until I saw a large dog "marking" the watermelons! EWWWWWWW! NOW I wash them VERY WELL! ugh! Now all that is left to do is to choose which method you would like to use! Cooking time does not include the hours of cooling. Have a great time!
