hello99- i always cover any food I put in the microwave (unless it is totally parve,like bread or a potato) Condensation does not appear in these circumstances. The only condensation you may see is from an open cup of water as it gest heated, thereby manufacturing steam. IF you would put a plate of soup- uncovered- in the microwave, you might have condensation and hence, if it is chicken soup, they stick to the walls. It still is a question whether the walls are hot enough to absorb it, and maybe that the condesantion just sticks to it, without being absorbed. (remember kdei kelipah)
