How to Can Butter
Couple things.
Those lids need heating so the rubber gaskets soften (as in the previous "canning chicken" video); just stick them in a bowl of hot water while you're doing the other tasks.
The other thing is, she's babbling about not using plastic as a reason for ladling the hot butter in a measuring cup and then pouring into the jars. Duh. The canning funnels are plastic and are meant for use with hot food. Just ladle right into the jars, using the funnel, from the pot.
Lastly, wipe off the jar rims really well otherwise the lids won't seal.
Other than that, she done good.
