While reading the food section of the Telegraph, I couldn't resist clicking on this video. What could I be doing wrong with Al foil? I was amazed (I know I'm sounding like a late night salesman) - how could I not know this after using both kinds of wrap for decades, not only at home, but in the course of my food work. After I watched it, I ran to the kitchen and looked at the boxes...sure enough, there's the tab and the instruction.
The wine bottle foil works with some bottles - not all.
Now, I'm watching the rest of this "Crazy Russian Hackers" useful videos. He's a kind of Heloise for the millennial generation. I love him.
