I'm sorry, Jon, I thought I had posted the solution. I dumped it all into a big bowl - the solid part was so concentrated that I almost had to trowel it out - and then worked it together, slowly and carefully, with an immersion blender, taking care not to overload the motor. If it started to labor, I would pull it up into thinner waters to catch its breath before I pushed it down again. Eventually (5 minutes?) it was all blended, whereupon I poured it back into the cleaned jar, and it's been good ever since.
