Add the second half of egg whites to the bowl. Fold the mixture while also pressing it against the side of the bowl periodically. You want the consistency to be like lava. No, I've never actually seen lava, but this is the most accurate description. It will still be somewhat thick, but will also slightly flow off of the spatula. This batter works best when it's not as thinned out as most other recipes. It will fall from the spatula but should not be able to do a "figure 8" into the bowl. You can watch the video below for more detail.
