The sun's finally out in London, so it's time to repost last summer's cheap, easy, no-mess cold-brew coffee technique. This is the best cup of coffee you're likely to drink this summer.
I bought a $10 "nut-milk" bag and a plastic pitcher. Before bed, I ground up about 15 Aeropress scoops' (570 ml) worth of espresso roast coffee -- the $20 Krups grinder is fine for this, take no notice of people who claim the blade overheats and burns the beans; it doesn't even get warm -- leaving the beans coarse. I filled the bag with the grind, put it in the bottom of the empty pitcher like a huge tea-bag, and topped up the pitcher with tap water (distilled water would have been better -- fewer dissolved solids means that it'll absorb more of the coffee solids, but that's not a huge difference). I wedged the top of the bag between the lid and the pitcher and stuck it in the fridge overnight.
In the morning, I took the bag out of the pitcher and gave it a good squeeze to get the liquor out of the mush inside. Add water to the pitcher to fill to the brim and voila, amazing cold-brew. You can dilute it 1:1 or even further.
Cleanup was easy: invert the bag over a composter, trashcan or garbage disposal, rinse off the bag, and you're ready to go.
This produced very, very good coffee concentrate, with only a little grit settled into the bottom 3mm of the pitcher (easy to avoid). It may just be the cheapest and easiest cold-brewing method I've yet tried.

Mister Alphabet is an action-figure designed to cleverly bend and contort into every letter of the Latin alphabet; the website is long on trademark warnings and arty Instagram photos, but short on details, like, “Is this an object of commerce?” and “If so, where does one buy it?” (via Kottke)
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
