Tiff burned the praline mixture and had to pour it out into this jar to contain it. That’s boiling, molten sugar.
I’m so glad I had Tiff’s macro lens on the camera when this happened so I could take this (…right after I ran to put a box fan in the window to exhaust the apartment so the smoke alarm wouldn’t go off.).
Update: She didn’t “burn” it - she just cooked it past the “praline” phase and well into the “dark caramel” phase (up to 350 degrees). My mistake.
