How to Can Crunchy Pickles
This page may contain affiliate links. More Information.
When I first started canning, pickles were one of the first things I tried. I didn’t just make a little batch to practice; I went all in and made over twenty quart jars of dill pickles. The flavor was good, but the texture? Terrible. They were soft, soggy, and downright disappointing. My family wouldn’t eat them, so they went to the chickens. (The chickens were happy — I wasn’t!)
It took me years to figure out what actually makes the difference. In this video and article, I’ll walk you through everything I’ve learned since then. From picking the right cucumbers to the processing method that finally solved it for me. Finally! I got the crunch!

Start With the Right Cucumbers
This is the stage that matters most, because nothing you do later can fully fix a cucumber that’s already started softening. Get this part right and everything downstream gets easier.
Freshness is Everything
The single most important thing for crispy pickles is freshness. The sooner you can get your cucumbers from garden to jar, the better your pickles will be.
Ideally, pick your cucumbers and process them within three to four hours. That’s not always realistic, so if you can’t get to them right away:
- Keep them cool.
- Don’t leave them out in the sun.
- Store them in the refrigerator or in ice water until you’re ready to start.
The fresher your cucumbers are, the firmer and crunchier they’ll stay once they’re canned. You can sometimes can them the next day… but same day you harvest is better. If you must wait, put them directly in the fridge.
- Harvest tip: Focus on small whole cucumbers. I tell my kids, pick when they are about the size of your thumb (they are teen boys just for size reference). You can certainly use them bigger. Many people simply cut them and make spears… but whole and small is better.
- Farmers Market Tip: Ask when the cucumbers were harvested and how they were stored. If you find a bin of cucumbers that are out in the heat and the farmer picked them 2 days ago. I’d pass.
Use Pickling Cucumbers
You can actually pickle any type of cucumber. But the varieties that are labeled pickling cucumber will have a firmer texture and turn out much better than a slicing cucumber.
Keep in mind that store bought cucumbers are often coated with a waxy coating to keep them fresh. This is not what you want for making pickles.
Keep them cold until your ready
If you can’t process your cucumbers right away, keep them in ice cold water. This keeps them cold, slows down any softening, and helps firm them up. Plus, they’ll absorb some of that cool water, which helps make them even crisper once they’re canned.
A Few Tricks Before you Jar Them
There are a few more steps that give you an edge before your cukes ever hit the brine.
Remove the Blossom End
This is one of those small steps that makes a big difference.
Look at the ends of your cucumber. Theres the stem end (where it was attached to the vine) and the blossom end (where the flower was). The stem end is often (not always) just a little bigger and rounder than the blossom end. The blossom end is often (not always) a little narrower and lighter in color.
The blossom end can contain enzymes that cause softening. To prevent that, slice off about ¼ inch from the blossom end as soon as you pick your cucumbers.
I like to take a small knife with me into the garden and trim them right there as I pull them off the vine. Removing that enzyme early helps stop the softening process before it even begins.
Try a Crisping Agent in the jar
There are a few commercial products that can help you achieve crispy homemade pickles. Choose one of these ingredients to try…not all at once! My preference is the Pickle Crisp.
Pickle Crisp Granules
This one is a product I DO often use. Pickle Crisp (by Ball) comes in a small plastic container filled with white granules. It’s made from calcium chloride. Its a a type of salt that helps preserve firmness.
Just follow the directions on the package. The measured amount is small: about ⅛ teaspoon per pint jar, or ¼ teaspoon per quart jar. Add it directly into each jar before you pour in your brine. It’s easy to overdo it thinking more will mean crunchier pickles, but a little goes a long way. No need to add extra.
Pickle crisp can be used in dill pickles, pickle relish, pickled peppers and other pickled foods. It is not just for cucumber pickles.
Alum
Alum is sometimes used for fermented pickles. Don’t confuse Alum with pickle crisp. They are not the same.
According to the Missouri Extension Service, Alum can increase firmness when used up to ¼ teaspoon per pint when you are fermenting. More than that can actually make your pickles softer, so measure carefully. Alum doesn’t help with fresh-pack (non-fermented) pickles.
Pickling Lime
Pickling lime has a great reputation for producing crisp pickles. You mix the lime with water and soak your cucumbers (usually overnight — check your package for directions).
Before canning, you must rinse them thoroughly. Soak and rinse in fresh water three times to remove all lime residue and make them safe for processing. Follow the directions for soaking and rinsing on the package closely.
Important: The rinse step afterward isn’t just about taste. Lime residue raises the pH of your brine, and that affects the acid level your pickles depend on to be safe.
Ball makes a food-safe pickling lime product that’s easy to find in most canning aisles and online.
Consider Grape Leaves
Some people swear by adding a grape leaf or an oak leaf to each jar of pickles you’ll get crispier crunch. It makes sense. A grape leaf contains natural tannins. These tannins help block the enzymes that cause softening.
It’s a traditional option that some canners still swear by. Make sure your leaf is rinsed and clean before you place it in the jar.
This Processing Makes the Biggest Difference
You can do everything right up to this point and still lose the crunch here, because how you process the jars matters as much as anything that came before.
Traditionally, pickles are processed in a water bath. But I have found that the Low Temperature Pasteurization method completely changed my pickling game.
A Boiling Water Bath Still Works
Just so you know, a standard hot water bath works. If you use it along with the other tips in this article; fresh cucumbers, a trimmed blossom end, maybe a crisping agent, you can absolutely get a good pickle. Don’t feel like you need anything fancier than a regular water bath canner to succeed here.
Having said that, plenty of canners (including me) find their pickles hold their crunch better with a gentler process. That’s where low-temperature pasteurization comes in. It’s not a requirement, just another method to try.
Use the Low-Temperature Pasteurization Process
This is the method that changed my pickling game. Instead of bringing your water bath canner to a full boil, you hold the water at a lower, steady temperature for longer. It’s gentler on the pickles, so they’re still properly preserved and safe.
You’ll need a reliable thermometer (I use a candy thermometer) to keep the water in the right range: between 180°F and 185°F, held steady for 30 minutes. Going below 180°F risks under-processing, and going above 185°F will actually soften your pickles, so keeping that thermometer in view matters.
This process isn’t for every recipe. Use it only when your specific pickle recipe indicates it’s approved for low-temperature processing. I use it with my favorite dill pickle recipe. Find the full step by step process including exact temperatures and timing here.
Frequently Asked Questions
Why did my pickles turn out soft even though I followed the recipe?
Soft pickles usually come down to one of a few things: cucumbers that weren’t fresh enough when you started, skipping the blossom end trim, or processing at a full boil instead of using the low-temperature method. Even a good recipe can turn out soft pickles if the cucumbers themselves had already started softening before they hit the jar.
What is Pickle Crisp made of?
Pickle Crisp is pure calcium chloride, a food-safe salt that firms up pectin in the cucumber without adding a salty taste or affecting the acidity of your brine. It’s different from table salt, which is sodium chloride.
Is Pickle Crisp the same as alum?
No. Pickle Crisp is calcium chloride, while alum is a different compound (potassium aluminum sulfate) that’s mainly used in fermented pickles. Pickle Crisp works in both fresh-pack and fermented pickles, doesn’t affect flavor the way alum can, and is the more commonly recommended option today.
Can you pressure can pickles?
No. Pickles are a high-acid food, so they’re processed with a water bath canner or the low-temperature pasteurization method, not a pressure canner. You’ll end up with mush!
Can I still eat pickles that turned out soft?
Yes. Soft or mushy pickles are a texture issue, not a safety issue, as long as they were processed correctly and show no signs of spoilage. They’re perfectly safe to eat; they just won’t have that crisp bite. If they are soft and slimy however… this indicates a problem. Slime is never a good sign and you should consider it spoiled.
Do I have to use a crisping agent to get crunchy pickles?
No. Crisping agents like Pickle Crisp, alum, or pickling lime can help, but they’re not required. Fresh cucumbers, a trimmed blossom end, and the low-temperature pasteurization process can get you crunchy pickles on their own.
Is low-temperature pasteurization safe for all pickle recipes?
No. Low-temperature pasteurization should only be used with a recipe that specifically calls for it. Not every pickle recipe has been tested for this method, so check your recipe before switching from a standard water bath process.
Final Thoughts
If your first batch of pickles turns out soft, don’t give up. We’ve all been there.
Use these methods — fresh cucumbers, trimmed blossom ends, ice water soaks, crisping agents, and the low-temperature process — to find what works best for you. And hopefully, you won’t have to share them with the chickens.
