My gravy turned to jello overnight. How can I make it last for leftovers? I slow cooked a pork shoulder with some veggies (carrots, onions, celery). When it was finished, I strained out the solids and proceeded to make gravy with the liquids:


Start separating liquids (I used a fat separator)
Brown some flour
Add some butter and whisk until lumps are gone
Keep whisking and add juices (now separated, less fat) and seasoning
Simmer to desired thickness


The gravy was delicious that night, despite having developed a skin fairly quickly. After refrigerating it overnight, however, it was a gelatinous mess, and wouldn't melt back down.

What happened? How can I make gravy last for leftovers?
I think you probably used too much flour for the amount of liquid in your gravy — instead of gravy, you made pudding. You might be able to thin it down by whisking in some additional liquid such as milk or water before reheating it.

However, next time use half (or even less) percentage of flour to liquid, and you'll have better results.
