Charcoal absorbs things like a sponge.

One teaspoon of charcoal has a surface area of more than 10,000 square feet.

That is quite interesting although the evidence isn't supported very scientifically and it doesn't explain the mechanism. I wonder if that's true about one teaspoon having a surface area of more than 10,000 square feet.

Still, it doesn't explain how peppers absorb the smell. I suspect they may in some way be neutralising or counteracting the smell rather than absorbing it. Chemistry rather than physics.

I'm still confused as to why the veg would smell differently when steamed in the microwave than when steamed over a pan. I assume they taste the same? I generally only microwave-steam potatoes, broccoli and green beans, and I've never tried it with frozen veg, or even pre-packed pre-prepared veg, so perhaps I'm missing out?

I've just wiki'd activated charcoal and, in a nutshell, it says that charcoal absorbant properties work using Van der Waals forces throughout it's incredibly large surface area. It says that "one gram of activated carbon has a surface area of approximately 500 mē". I can't be arsed calculating a direct comparison with the "one teaspoonful & 10,000 square feet" that Chem4Me found but, if anything, the wiki reference sounds even bigger.

Hi fishytails

Sorry if that's not clear. The smell is exactly the same regardless of how it is cooked. Now I understand why you suggested it might be caused by old food in an unclean microwave.
