Take a spoon and transfer the crystallized honey into an empty and clean jar. If the existing honey jar is plastic, remove the lid and squeeze the honey into the clean glass jar. You can even use a mason jar.
If the honey is too difficult to remove from the plastic container, run the plastic honey jar under hot water from the faucet and try to squeeze it out. Water from the tap doesn’t generally get too hot, so this process shouldn’t harm the plastic.
If the honey is particularly stubborn and you can’t even get out the crystallized honey, go ahead and put a bowl in your sink and fill it with hot water. Place the plastic container in there and let it soak to soften it up a bit. You may have to reheat the water a few times.
Fill a saucepan about 25% of the way with water and heat it up on the stovetop. We don’t want the water boiling, but we do want it to be hot. Once the water is roiling, turn the temperature to low.
Loosen the lid on the honey so that air can escape but leave the lid on. Place the jar of honey in hot water. Make sure the top of the honey jar should is not covered with water. Otherwise, water will enter the jar, and that is something you don’t want. Also, do not lay the honey jar into the water, as it will allow water to flow in.
After the water cools down and reaches room temperature, remove the honey jar, and check for crystals. Tilt the jar just a little, to make sure the honey is moving.
Continue to repeat the process, until the honey has fully liquefied. After the honey has fully softened, store it in a clean and warm place in your kitchen.
Notes
The times will vary based upon how stubborn the container is and how long it takes to heat up the water.
