Place half of the baby cucumbers into your mason jar or pickle crock.

Add garlic, peppercorns, and chilis. Top with remaining cucumbers and press down so the ingredients are tightly packed.

Mix together water and salt until salt is dissolved.

Top second layer of baby cucumbers with salt water solution until the brining liquid is about 1-2 inches past the top of the cucumbers. Use some sort of weight to ensure all of the pickles are submerged. Brine pickles for at least 3-5 days, and up to a couple weeks.

Make sure to keep a bowl under the jar of fermenting cucumbers, as it can sometimes overflow during the pickle fermentation process. You will see bubbles form and you can "burp" or lift the weight up every few days to release those.
