@LifeTimeCooking Wide-mouth jars are far superior for fermentation. I have the pickle pebbles and pickle pipes for multiple jars now, so that everything can let out gasses, without collecting unwanted bacteria. The weekend was my mini-fermentation party, since I gave away a lot of jars over Christmas. Also, I had a bit of additional time at home.

@Bumblefish Peanut butter that has separated is very dense and a cappuccino whisk wouldn't have the power to mix it. My old electric mixer was high powered and it balked at the start of mixing the top 1/3 which is the softest of the jar. My newer mixer isn't as powerful and struggles to mix it all.
