Was a bartender for about six years (yeah, profile pic) and while we didn't have a grill in the club, our staff had alot of BBQs. These might be good for a pork butt:
1pt triple sec (grand marnier if you want a great drink)
1pt lime juice
2pt good white tequila.(Patron, Don Julio, Herradura, etc)
Shake, serve over ice in salted rocks glasses with a lime twist.
This can also serve as a base for other drink ideas. Mixed double or triple strong, then added to OJ, or lemonaide, it makes a nice hot-summer cocktail.
1pt fresh lemon juice.
2pt Cogniac (I prefer Hennessy or Remy)
Shake with ice, serve in sugar rimmed martini glasses. Coat a lemon wedge in sugar and serve on the side of the glass for more better Homes and Garden's points. Can also garnish with mint or basil sprigs.
My Own Party Punch
3/4 gallon of your favorite (mine's usually homemade) lemonaide
325ml Coconut rum (1/2 a 750ml bottle)
4 oz ammareto (two full shot glasses)
Small jar of marichino cherries, pureed in blender or food processor.
Fills gallon jug, a few pitchers with ice. A bit sweet for hotter days, but very nice in a shady spot by the lake or river.
You might also want to check out Mojitos. I hate making them, and hate asking for them at bars since they are a pain to make, but they are nice and refreshing
Personally, I go with a mix of nice beers and cheap beers, and let friends arrive with wines and liquor. Always good to have some light beer on hand so your buddies can maintain a buzz without getting "sleepy". I try to stay local microbrews for the good ones, and like Olympia and Hamms for cheap beer. Thank god I live in a county with four world class breweries, and host to the California Beerfest!
