Microwaves are too quick and tricky for my liking. It's easy to over-heat.
I would put the jar in a pot of water and heat it slowly on the stove. That's how I warm mine if I don't have time to let it thaw on its own.
So I just made my first back of rendered fat today for some winter confits. I put the majority of it in the freezer for later usage and began to wonder - if I use a microwave to melt the frozen fat, am the ruining it? If so, how can I get it up to warm temperature? Hot water run over the mason jar seems like the only other option.
Can you put rendered fat in the fridge for regular consumption like morning eggs? If so, how long does it last?
