How to Make Fermented Watermelon Rind Pickles and Relish
Step 1: Prepare Your Equipment
Start by gathering your fermentation equipment. This recipe works best with a 32-ounce wide-mouth jar. Make sure everything is clean! Wash all your equipment—your jar, weight, and lid—to avoid introducing any unwanted bacteria into the mix.
Step 2: Prep the Watermelon Rind
Next up, wash your watermelon rind under cool water. Then, using a vegetable peeler, carefully peel off the outer skin. I found that peeling gives the pickles a better texture since the skin can be quite chewy. Slice the rind into your desired shape; whether you prefer slices or chunks is entirely up to you!
Step 3: Weigh Your Ingredients
Using your kitchen scale makes it easy to measure out exactly what you need. Tare/zero your scale with an empty mixing bowl on it before weighing out the chopped watermelon rind. Once you have 300 grams ready, add it to your jar along with 400 grams of water.
Step 4: Add Salt and Spices
Weigh out 25 grams of sea salt and add it to the jar containing the watermelon rind and water mixture. If you’re planning on adding dry spices like peppercorns or garlic powder, consider placing them in cheesecloth or a tea bag first. This way, they’ll infuse without floating around in your brine.
Step 5: Shake It Up!
Secure the lid on your jar tightly and give it a good shake for about two minutes. This will help dissolve all that salt into the liquid—making sure every piece of rind gets that delicious salty goodness!
Step 6: Submerge and Ferment
After shaking, remove the lid and place your fermentation weight inside the jar. The weight should keep all pieces of rind submerged beneath the liquid—this is key for proper fermentation! Secure everything back together and let it sit at room temperature for about 14 days. Place it in a glass dish just in case there are any spills!
Step 7: Taste Test Time
After two weeks have passed, check on your pickles! Remove the fermentation weight and give them a smell and taste test—you’re looking for that pleasantly sour aroma paired with tartness from the rinds.
Step 8: Make Into Relish (Optional)
If you’re feeling adventurous (and I always encourage that!), strain out some brine from your fermented watermelon rinds. Finely mince them along with half an onion before mixing everything together with apple vinegar, honey, and reserved brine.
Step 9: Store Your Creation
Transfer your relish into an airtight container and store it in the fridge. Enjoy it as a topping on burgers or salads—it’s sure to impress everyone at your next gathering!
By following these steps closely while keeping things light-hearted in the kitchen, you’ll find yourself enjoying homemade fermented watermelon rind pickles and relish in no time at all!
Pro Tips for Making Fermented Watermelon Rind Pickles and Relish
Making fermented watermelon rind pickles and relish is a delightful journey, and a few tips can make your experience even better!
-
Choose ripe watermelon: Selecting a ripe, juicy watermelon ensures that the rind has the right texture and flavor for fermentation. A fresh, flavorful rind contributes to the overall success of your pickles.
-
Use filtered water: Opting for filtered water helps avoid chlorine and other impurities that might interfere with the fermentation process. Clean water creates a better environment for those beneficial bacteria to thrive!
-
Keep it cool but not cold: While fermentation thrives at room temperature, keeping your jar in a slightly cooler spot (like in a pantry) can slow down the process if you’re in a warm climate. This helps prevent over-fermentation and keeps flavors balanced.
-
Taste test along the way: Don’t hesitate to sample your pickles as they ferment! This will give you insight into the development of flavors and help you determine when they reach your preferred tartness.
-
Label your jars: If you’re making multiple batches or trying different variations, labeling your jars with the date will help you keep track of fermentation time. This way, you’ll always know when it’s time to taste!
