This one reminded me of what happens if you beat egg whites in the process of making meringues. Done right, one gets a pattern formed by the beaters that does not look too different from the above (except for the colour). I would not actually add chocolate to egg whites as the fat in the chocolate tends to make the meringue collapse. Think of the colour in the images as a touch of artistic license.

Today's Gratitude Item: That so far, my dad is recovering well from the major surgery he had yesterday. Here's hoping and praying that all continues to go smoothly!
