Optional Weevil Meeting Cocktail Recipes

See no weevil


In a shaker add:


Shake and pour over ice. Sprinkle with cottonesque toasted coconut and dust with cinnammon. 


"The people of Enterprise didn’t just overcome pestilence — they were thankful for it. It all began in 1915, back then everyone in town grew cotton. That is until the bowl weevil showed up, the evil insect had just destroyed Mexico’s cotton crop. Now it was happy to chow down on Alabama’s. Enterprise farms were wiped out. That is until a local named H. M. Sessions did some research and learned the area was great for farming — peanuts. The first crop hit it off big time.

Soon other enterprising Enterprisers switched to peanuts too. Eventually the weevils moved on to wider, fluffier pastures. But the pest had taught the locals the value of diversifying their crops. So in December 1919, they erected a monument to the boll weevil honoring it as quote, “a Herald of prosperity.”

The monument looks kind of like the Statue of Liberty but instead of a torch — she’s holding a giant weevil. It’s not the original monument. Some teenage boys ripped

the weevil off that one — along with both the statue’s arms."

Mississippi Planter's Punch



Dissolve the sugar with a little water in a mixing glass. Add the lemon juice, then the rum, Bourbon, and brandy. Fill with fine ice, clap on the shaker, and go to work. When well frappéd pour into a long thin glass. Decorate with fruit and serve with a straw (option). 


"If this cooler doesn't make a Mississippi cotton plant forget about the boll weevil, charbon, and high water, give up trying to make [them] forget. All that is lacking in the recipe is a shady gallery, a rocking chair, and palmetto fan.
