What's the best way to keep honey from crystallizing?
The best way to keep honey from crystallizing is to store it at room temperature, notes Weintraub. The most ideal storage place is in a dark cupboard away from direct sunlight. Avoid storing it in the refrigerator, as cooler temperatures will make honey crystallize faster.
When the temperature of the honey dips below 50°F, the crystallization process will accelerate. Don't store honey in a chilly basement or unheated mudroom. To slow crystallization naturally, store your honey at room temperature or warmer (the warmer the better). Store honey in glass jars instead of plastic.
Pour warm water (water should not exceed 110º F) into the pan and allow to sit until the honey melts. In five-minute intervals remove your bottle from the pan, stir the honey and return it to the warm water. Continue this process until the honey has returned to its liquid consistency state.
One of the reasons most grocery store honeys will not crystallize is because they have been pasteurized, which requires high heat. The most ideal temperature to induce crystallization is 57F–the further you get away from that number on either side, the slower a honey will crystallize.
Store honey in a cool (50°-70°F) and dry location. Storage temperatures above 70°F will compromise the quality and nutrients of the honey over time. Cooler temperatures, i.e., cold storage or refrigeration, will quickly crystallize honey and should be avoided.
To fix the problem temporarily, you can place the jar in a saucepan with about an inch of water, gently heat it until it liquifies, and transfer the now-smooth honey to a clean jar.
What Honey Does Not Crystallize? One exception to this is Tupelo honey. Tupelo honey has a very high fructose content and low glucose content, so Tupelo honey will almost never crystallize. Because of the low glucose level, Tupelo honey has a low glycemic index.
For best quality, store honey for up to 12 months. After that time, it remains safe but the quality may not be as good. Honey can become cloudy, crystallized or solidified but this is not a safety concern. The honey can be microwaved or heated in a pan of hot water to clarify or melt it.
Don't liquefy honey over and over again.
Decrystallize only what you need at one time. The flavor and aroma of the honey will fade with repeated cycles of heating and cooling (and liquefying and crystallizing).
You can also decrystallize honey in the microwave directly. This works best with honey in glass containers, as the microwave will warp and melt a thin plastic bottle. Transfer the honey to a microwave safe container if it is not already in one.
Why is my store bought honey crystallized?
Why Does Raw Honey Crystallize ? Honey is a super-saturated solution of primarily two sugars: glucose and fructose. Just like with your powdered lemonade, it is a natural process for some of the sugars in a super-saturated solution to eventually come out of solution. All raw honey will crystallize due to glucose.
From a calorie and sugar content perspective, the differences between sugar and honey are minimal, however, overall, honey contains slightly more health benefits than table sugar from its potential antioxidant, antibacterial, antifungal, and anti-inflammatory properties.

Normal Changes. Even though honey doesn't have an expiration date, it can still undergo natural changes. The National Honey Board says that over time honey may “darken and lose its aroma and flavor or crystallize,” depending on changes in temperature.
In general, honey doesn't spoil. However, it can go bad if it's contaminated or incorrectly stored. If your honey has visible mold, or if it smells fermented or "off," then it's time to toss it.
Keep honey in sealed container.
Glass jars with lids are also ideal for storing honey as long as the lids are on tight so the honey won't be exposed to air, while not being used. It isn't recommended to store your honey in non-food plastic containers or metal containers because they can cause honey to oxidize.
Pasteurized Honey
Processed, or pasteurized, honey is treated at high temperatures to destroy sugar-tolerant yeasts and extend its shelf life. This type of honey should be stored in a warm, dark place or anywhere it won't be susceptible to crystallization.
When it's stored properly, honey never goes bad, Grad said in an interview with Allrecipes. "Honey will darken and/or crystallize, but it is still safe to eat," she said. Metal or plastic containers can oxidize the honey, and heat can change its flavor.
Thankfully, honey can be returned to its liquid state with little effort. Heat some water in a pot, and put your honey container in the pot of hot water until the honey turns liquid. This gentle transfer of heat to the honey helps bring it back to liquid form without overheating the honey.
