Back in January of 2014, I backed a kickstarter for a coffee brewer called the Duo Coffee steeper, and I love the darned thing with a passion. It's my favorite coffee brewing method of all time, and I've used it nearly every day since July of 2015 when I received it.
The one (and only) thing I'm less than enthused about is the lid. It works fine. It's functional, looks good ... but it's made of plastic, something I avoid using with hot liquids. For coffee brewing, I really just want stainless steel, glass, ceramic, and if necessary, silicone. You know, ingredients that have stood the test of time, and are safe. Inert.
I started playing with ideas almost immediately - lining the lid with a sheet of stainless-steel foil, but I never did figure out how to adhere it. Besides, I don't really want glues near my food, either.
This weekend, I was planning to take my inner brew chamber/lid to the nearest Goodwill or even Bed Bath and Beyond to see if I could find a lid small enough to fit, even if it was intended for a different use Then I started looking around at home to see what small lids I already had. The lid of the asparagus steamer? Nope. Too big. Then it hit me - the red silicone-and-glass lids of our Pyrex storage bowls (smallest, two-cup size) might be about right, and I have an extra one (after I broke a bowl). Bingo!!
And because of the silicone seals, it actually stays on just as well as the original lid.
The only thing I might need to worry about is that the lid will actually seal, and as water condenses on the inside, it will cause a bit of a vacuum, so I may need to drill a tiny hole through the silicone to allow pressure to equalize.
