  • Umbra on Jell-O shots

    Greetings, A very important discussion among my colleagues this week: is it better to purchase reusable, petroleum-based products (plastic) or to use paper disposables? Specifically, we’re talking about Jell-O shot cups. A recent (and brilliant) invention is this little plastic shot cup with a twistable ring inside. Ostensibly, a flick of the wrist will free […]

  • Umbra on cooking oil, again

    Dear Umbra, You missed a fantastic opportunity to promote biodiesel use of the cooking oil. There are many people collecting frying oil from restaurants and the like, and perhaps the reader could find a person collecting as well. Check newspaper ads for persons collecting or check the restaurants in your neighborhood for who is collecting. […]

  • Umbra on living Christmas trees

    Hi Umbra, I’m surprised that in your column on Christmas trees, you didn’t mention the option of living trees, although I know they cannot be subjected to our warm indoor temperatures for very long. Can you discuss the option of living trees, how to treat them indoors, and what to do with them after the […]

  • Umbra on used cooking oil

    Dear Umbra, It’s always nice to look through cookbooks and to watch cooking shows that feature yummy deep-fried food, and I have often been tempted to try and cook my own creations. However, no one ever seems to mention what they do with the used cooking oil, especially after deep-frying. What is the best way […]

However, in my constant imbibing of the dark elixir, I’m concerned about the energy use involved. Specifically, I can only drink coffee […]

We try to be as eco-friendly as possible: our cafe is local, organic, and vegetarian, we use compact fluorescent bulbs where we can (although cannot find an alternative for the halogen lighting systems we have), we use eco-friendly […]

  • Umbra on fireplace ashes

    Dear Umbra, What should we do with ashes from the fireplace? I’ve heard that they’re great for the garden and I’ve heard that they may not be so good for the garden. Are they a good replacement for salt on slippery sidewalks? Janet Allen Syracuse, N.Y. Dearest Janet, Why not make some soap? Here come […]

  • Umbra on cats and birds

    Dear Umbra, I have three cats, and live in a close-in suburb of Boston. I love the cats dearly, and let them outside during the day to wander about, and generally not have to live an indoor, sedentary, boring life. My question concerns their hunting instincts: I haven’t had any luck with any particular way […]

  • How to recycle athletic shoes, iPods, mattresses, and other oddities

Athletic Shoes Got a pair (or a pile) of old sneakers that are too gross and grotty to […]
