The friends at SCRATCHbread and their insanely delicious concoctions are not only at the Brooklyn Flea every weekend but they happen to throw their own events. I can't say where this next one is held so if you sign up for their SCRATCHbread newsletter you just may get the scoop on these assemblies (we have that right as 'Mericans). Also, if you're into the whole social play of grassroots funding for businesses, check out their 'Right to Deliciousness' campaign on KickStarter.com, a cool way of getting support for your cause, whatever it may be. Since Brooklyn is all about homegrown businesses (have you seen West Brooklyn lately?) maybe it will trend as well as Groupon has.
The other thing is Sailor Jerry Spiced Rum who helps sponsor Williamsburg jelly pool parties with some very good bands over the course of several Sundays this summer. I doubt newfangled hipsters would appreciate Cap'n Jazz, but hey, I'm not here to flick snob snot at anyone (they did not end up playing due to weather). For more on Sailor Jerry, go to their official site.
Cheers to the weekend!
