We don’t recommend that you eat frozen peanut butter while it’s still frozen or partly frozen. Here’s why...
When you thaw out frozen peanut butter you will see a natural separation occurring as the oil separates from the solids. It’s the same process that you will see if you had left the peanut butter in the cupboard.
So for best results you should allow the peanut butter to properly thaw before you use it in a meal, snack, or recipe.
The best way to do this is to let the peanut butter thaw in a refrigerator. This is because this method helps to slow down the separation of the oils and the solids we described earlier known as syneresis. Remember to remove the lid, as this will help it to better thaw.
Sure it takes longer to thaw this way, but that’s how you get the best possible results.
When you’re satisfied that the peanut butter has properly thawed, be sure to give it a good stir for a few minutes to gently reincorporate the natural oils back into the emulsion.
