My lemon meringue pie filling just refused to set last night

I followed my grandma's recipe exactly, even used a fresh lemon from my tree. The cornstarch slurry looked right, but after I poured it back into the pan to thicken, it stayed soupy for over 20 minutes. I ended up adding another tablespoon of cornstarch mixed with cold water, which finally did the trick after a lot of nervous stirring. Has anyone else had a cornstarch thickener just decide not to work?

My pies usually look like abstract art anyway so I'm right there with you.

Cornstarch can be weird if the heat's not high enough.

My grandma taught me to mix cornstarch with a little cold water first, @dakota_murphy90. If you add it straight to a hot but not boiling gravy, it makes those weird little clumps no one wants. Getting the slurry right is half the battle.
