Why is my marmalade hard almost like candy once refrigerated?
I've been trying to make this kumquat marmalade in the microwave from a recipe that I found online. It's super easy and I just heat the marmalade mixture until the mixture hits 220 and passes the gel test on a cold plate. But twice now, the marmalade is like super thick candy once refrigerated. It's delicious if you can dig it out, but totally not spreadable at all. What am I doing wrong?
