Whether looking for information or trying to get into the Slug Club, this crystallized pineapple is sure to impress any Harry Potter fans!Jump to Recipe
Before reading Harry Potter, I had never heard of crystallized pineapple before. Actually, I hadn’t heard of crystallized fruit of any kind. The only “crystal” candy I’d had was the rock candy that you can make at home with a string and a cup of sugar water. In some ways, this is similar, but it isn’t pure sugar you are eating and has a lot more flavor.
You’ll be sure to impress Professor Slughorn with this recipe, just don’t ask him about Horcruxes when you do!!
His [Professor Slughorn] little feet resting upon a velvet pouffe, he was sitting well back in a comfortable winged armchair, one hand grasping a small glass of wine, the other searching through a box of crystallized pineapple.
“What with your uncanny ability to know things you shouldn’t, and your careful flattery of the people who matter – thank you for the pineapple, by the way, you’re quite right, it is my favorite-“
-Harry Potter and the Half-Blood Prince
When I think of crystallized pineapple and the rock candy I used to eat, I figured I could try to put the two ideas together and make my own pineapple snack. Of course, being pineapple is so water-infused, I realized I would need to dry it out in the process so it wouldn’t be a wet and sticky mess.
I used a fresh pineapple for this recipe. But if they are out of season or you don’t want to deal with cutting one, you can also buy a can of pineapple rings. It’s also up to you if you want to keep the pineapple in rings or cut it into bite-sized pieces. We did the bite-sized because it was easier to work with and better for the boys to eat.
Step by Step
If you buy a fresh pineapple, start by cutting and coring the fruit. You can see my favorite tool and method here: The Easiest Way to Cut and Core a Pineapple.
Start the simple syrup by pouring 4 cups of water and 2 cups of sugar into a large saucepan and set it to high heat. While it warms up, stir continuously until the sugar has dissolved completely.
Once it is at a rolling boil with a candy thermometer reading about 235F, add the pineapple into the pan. Bring it back to a simmer.
Cover the pot and let it simmer for about an hour. You want the pineapple to start to look translucent. Stir occasionally, just enough to make sure the pineapple doesn’t stick to the sides or bottom of the pan.
After it’s done cooking, take the pineapple out. Transfer it to a wire rack. Place either a pan or some paper towels underneath to catch the drippings. Remember, it’s simple syrup so it will be sticky and not very fun to scrub off of a countertop.
Let most of the syrup drip off of the pineapple, then move it to the dehydrator. Check the settings for your dehydrator since they all vary. I borrowed my father-in-law’s dehydrator which is probably older than me or close to it. So I’m sure the directions are very different for newer ones.
If you don’t have a dehydrator, you can dry the pineapple out in the oven. Keep it on the cooling rack, as long as it’s one that can go in the oven, and put a pan underneath to catch the drippings. You think it’s hard to clean off a counter? Imagine an oven! Set the oven to 200F and cook until it’s dry which will probably take a few hours.
When you have your dried out pineapple, sprinkle it with just a little more sugar, and it’s ready to serve! You can store this in an airtight container on the counter for up to a month. I’d be surprised if it lasts that long. Mine only did because I was out of town for two weeks. But it was just as delicious when we got home!
I’m thinking about making another batch before our next road trip to have a snack while we drive. I saved the syrup that the pineapple cooked in and it’s sealed in the refrigerator.
I haven’t found a use yet. It’s delicious when added to a strawberry daiquiri!

Fantastic idea! I will try to recreated it using my oven as I have no dehydrator but this pineapple looks devine! The perfect summer snack!
I haven’t tried it in the oven, yet, but I may next time. The dehydrator was my father-in-law’s so I don’t always have it here.
I love pineapple but have never heard of this before and definitely haven’t tried it! I bet it’s lovely and sweet, I am so going to try it!
You’ve got it, the pineapple is so sweet and delicious when it’s prepared this way.
A technique borne from necessity but now practiced as a luxury.
It’s so true! I hardly ever use the dehydrator, but I know it was the best method for a lot of things long ago.
I was so excited to try this. I ended up using canned pineapple because im horrible at knowing when fresh pineapple is ready. It took so long to get to 235, and by the time i saw it reach the temperature (which i had to keep taking my candy thermometer off to get a good reading because it kept going low with how i had it set), it had actually gotten almost to 300 in the 5 minutes between checks. I managed to not completely mess up the sugar syrup at first. But i guess i forgot to cover the pot, because in 40 minutes the pineapple was burning and instead of still being yellow like your pictures, they were a dark yellow from the sugar syrup burning it. And that was with me turning the temperature of the stove down to medium. What did i do wrong, other than not covering the pot? How long should it have taken to reach 235? Im so upset because i was really looking forward to the pineapple.
Hi Alex, I’m so sorry to hear this didn’t turn out well! It’s been a little while since I made this, but I believe it took only about 10-15 minutes for the simple syrup to get to temperature. I have a gas stovetop, though, so sometimes it cooks a little quicker than others. I’m not sure if the canned pineapple makes a difference because I’ve only ever used fresh pineapple. Covering the pot definitely helps to keep the moisture from evaporating. It may also help to use a smaller but deeper pot next time so the liquid isn’t so thin. I hope this helps and it turns out for you next time!
Also, to check the freshness of a pineapple, smell the bottom of it. When it smells sweet, the pineapple is ripe and ready to cut 🙂
Oh, this looks super yummy. I will definitely have to try this. I love trying new recipes!!
It was such a perfect sweet snack! I hope you enjoy it!
Wow! This is new from me! I like pine apple so much! I will try to do that someday! Thanks for sharing the ingredients 🙂
Pineapple is one of my favorites, too! I could eat it almost any way it’s prepared.
I definitely want to try this! This looks super yummy 🙂
You should! I absolutely loved the recipe, it was so delicious.
I am definitely going to try to make this. My husband has been trying to convince me to get a dehydrator so this may push me over the edge.
I really want to get one, too. I had to borrow my FIL’s for this recipe but want to make it again and would need a dehydrator.
I can imagine it would be a fun snack. I have always wanted one of those dehydrators. They look fun and you can do so much with them.
Me, too! I think I am putting one on my Christmas list this year. This was the first time I used it, but want to try so many recipes in the dehydrator.
So yummy! I will definitely make again.
Awesome, I’m so glad you enjoyed the recipe!
oh yum! I love pineapple and I have never even heard of doing this! What a fun idea!
Pineapple is my favorite fruit, and it’s even better when crystallized!
Didn’t know that crystallized pineapples were a Harry Potter thing. I would love to make these for a snack!
They are mentioned briefly, but I’ve read so many times that I found all those small mentions of food 🙂
I love pineapple! Since going Keto though it’s off my food list. Definitely something I’ll save for future though once I begin carb cycling.
Oh man, if pineapple isn’t keto I don’t know if I could do it! It’s my very favorite fruit.
Adding a dehydrator to my kitchen wishlist! It looks like a great one to have on hand for yummy snacks like this.
I am borrowing my FIL’s and have had it for over a year now! He uses it to make jerky, I use it for yummy treats like this!
This is a wonderful recipe! I had not made this before, but it was super easy and fun to make!!
Thanks, Angela! It’s so easy, just take a bit of time to let the dehydrator work. But I’m glad you enjoyed it!
This sounds awesome! Did it still have its pineapple flavor when it was finished?
Hi! It’s delicious and does retain a lot of the pineapple flavor when it’s done.
It’s a perfect complement to a sweet and salty mix when paired with my candied maple bacon jerky!
Oh, my younger son is a bacon-lover already, I can’t imagine how much he would eat if it was candied!
