I was preparing my latest favorite work-suitable drink a few minutes ago, and a drop of tea spilled over the side of the mug and ran down to the base. Naturally it immediately spread around the entire base, forming a ring on the desk. It was easily wiped up, but then I thought—why does it always spread around the entire base to form that unmistakable coffee ring?

It occurred to me that it might just be capillary action with the liquid flowing along the V-shaped channel formed by the table and the edge of the mug. Some googling did turn up the fact that ring-shaped coffee stains from single drops are caused by capillary flow: as the drop evaporates, it draws water from the inside.

But the instant ring from the mug? Either it’s something else, or it’s so obvious no one has throught it worth writing about.

Edit: *sigh* Read first, then post. I was just reminded that capillary action specifically refers to fluid moving against gravity. Any other thoughts?

The Coffee Bean and Tea Leaf has a drink they call a Moroccan Mint Latte. It’s a tea latte with chocolate. You can get a fairly good approximation by making hot chocolate using mint tea instead of hot water. Katie suggested Bigelow Plantation Mint (after I mentioned that I’d tried it with Stash Moroccan Mint), which seems to work well.

Update: I forgot to mention the key difference between the two varieties of tea that I tried. Black tea works better with chocolate than green tea.

Pickle-and-onion Catamaran

You know how some restaurants always give you a pickle with their sandwiches? Well, at Ruby’s today I finished, picked up the toothpick flag that had been stuck in the hamburger, turned the pickle over and planted the flag, declaring it to be a boat. Katie immediately took her pickle and a leftover onion slice and turned it into an outrigger. A bit more manipulation, plus a napkin for a sail, and it became a catamaran.

Our waiter did a double-take when he picked up the plate, then set it down on the counter. We like to think it was so the other waiters could see it.

We have four coffee-house chains in the area, in addition to local places.

My favorite is Diedrich Coffee, with a couple dozen locations in Orange County, two each in LA and San Diego… and three each in Houston and Denver. (In the last few months, Diedrich has started selling T-shirts that say, “Venti, Schmenti.”)

Then there’s Kelly’s Coffee and Fudge Factory, which had about five locations the last time I checked but now has about thirty scattered around Southern California with one more in Lake Havasu… and according to their website, they’re opening one in Riyadh. Yes, Riyadh.

And then there are the international chains. Coffee Bean and Tea Leaf is all over the American Southwest and Southeast Asia. Starbucks, of course, is everywhere.

At one point we had all four chains in one mall. The first phase of the Irvine Spectrum had a Diedrich Coffee attached to the Barnes & Noble, before the bookstore hooked up with Starbucks. The second phase added a Coffee Bean. The third phase added a Kelly’s, and the Barnes & Noble moved to the new section… and added a Starbucks coffee bar inside. Unfortunately the Diedrich’s was off in a corner, and without the bookstore to bring people in, it eventually closed.

Edit: I can’t believe I forgot these, but if you really look for them, you can find Peet’s and Seattle’s Best. Neither has many stores in the area, though.
