I completely ruined the matzo ball recipe from VWAV last month. Last week, it was finally time for a rematch.
I took the advice of Jewish Vegan and Isa and made smaller balls over lower heat. I also used a food processor instead of a blender this time. It worked! They stayed solid! The masses rejoiced!
They still weren't as firm as my family likes them, but it's a start. Next time, I'll add an extra dash of matzo meal.
Before and after (not that you can really tell much of a difference at this resolution. Higher res at my Flickr):
