8 Bonus Tips For Making Crunchy Lacto-Fermented Pickles

1. Use a Saltier Brine

The salt in the brine prevents harmful bacteria from growing. Then, the healthy lactic bacteria can produce lactic acid to preserve the cucumbers.

The healthiest choices are natural sea salt and Himalayan pink sea salt.

We recommend using a salt brine mixture of 4-5% instead of 2-3% or lower. This will bring out the taste and crunchiness.

My family prefers a 4% salt brine; it's not too salty and provides a satisfying crunch factor.

*A 4% salt brine converts to 2 tablespoons of salt for every 4 cups of water.

While a 5% salt brine is 2.5 tablespoons of salt for every 4 cups of water, this was a little too salty for my taste, but it could be perfect for you.

By using a higher percentage of salt brine, you will preserve the crispiness of the pickles. Beware, though, you don't want to overdo it because if they are too salty, you might end up throwing them out.

2. Use Small Whole Cucumbers

Small cucumbers tend to keep their crunch better than larger cucumbers. When buying cucumbers, choose the Persian cucumbers over Kirby's.

Kirby's are already quite crunchy and better suited for a quick pickling process. They don't hold up as well through the longer fermentation process. Traditional Kirby cucumbers get mushy on the outside during fermentation.

If you use larger cucumbers, do not cut them into small pieces because they tend to become soft.

It's best to choose a little cucumber and divide it into large spears. This will ensure the best-tasting pickles for your recipe.

3. Use Fresh Cucumbers

Fresh is best when it comes to fermenting pickles. If you notice your cucumbers are wilting, throw them out. Grocery stores always put the freshest produce in the back and the oldest in the front.

Fresh cucumbers have the most nutrients and health benefits, so take the time to find the best ones!

The cucumbers should have no soft spots and should not look wrinkly. If they have either, then they are on the way out.

Fresh picked cucumbers from your garden or the farmers' market work best. Using small Persian cucumbers makes the crispiest and crunchiest pickles.

4. Remove the Blossom End

The end of a cucumber contains enzymes that soften pickles. Cut a thin slice from the end to preserve the firm texture. This will keep the enzyme from softening the cucumber before it's fermented.

5. Puncture the Skin

Cucumbers harvested a bit late in the season or have been on the vine longer will develop a thicker skin.

A great way to improve their taste and texture is to prick a hole in each cucumber with a knife or skew. This will allow the brine to penetrate faster, and the cucumbers will culture better.

6. Chill Cucumbers in an Ice Bath

Chilling cucumbers in an ice bath for four to five hours before starting to process them will help improve the crispiness of the pickle.

Use a large, food-safe container and fill it halfway with ice before pouring in water. Replace the ice as needed to keep the cucumbers cool.

7. Ferment at the Coldest Temperature You Can

The ideal temperature for fermenting pickles is between 60-70°. Anything much warmer than that will result in mushy pickles. Stay in this range for the best results.

However, if the temperature is over 70 degrees, then shorten the fermentation time. Do a taste test after three days to determine their level of crunch. They are ready if they taste great and have the crunch you desire.

8. Pay Attention to the Color

The color of the cucumber is another indication of readiness. The batch is ready to eat when the cucumber changes from bright green to an olive or yellow-green color and the inside is translucent.
