You can also try to add fresh EA again on top of the goo and force stir it into solution. Add some citric also. Goo may break up and xtalize nicely if it is water based. You may have dislodged a small ammont without stirring before which subsequently xtalized. By stirring you may get it all to interact with fresh EA/citric.

Yes, the -10C delta between decanting and xtalizing, together with not having excess citric to maybe absorb water, may be why you got goo from excess water.

Condensation is not an issue for me, just work relatively quickly. You should see some water from the EA on the bottom and walls, that would be a good sign.
