Truly fermented foods are the backbone to traditionally prepared meals. There's something so rewarding and soothing about enjoying the fruit of your labor that you've worked so hard on weeks prior.

🧂What is Pickling Spice
Pickling spice is a common canning and fermenting spice blend consisting of several spices that give amazing flavor to canned and pickled goods. Although the exact blends vary, the most basic pickling spice starts with black peppercorns, mustard seeds, allspice berries, coriander seed, crushed bay leaves, and dill seed.
This blend of spices adds tang and distinct essence to the salty brine. It holds up incredibly well over long fermenting periods and yet flavorful enough to retain their pungency and infuse their aroma into the fermented veggies.
It's fabulously convenient to have pickling spice on hand for an easy and quick fermenting session.
📖Substitutions and Variations
- No pickling spice? Use any combination of these spices to make 2 teaspoons: black peppercorns, mustard seed, allspice (go easy on this - it can be overpowering), coriander seed, crushed bay leaves, and dill seed. Flavor will vary depending on what you use but it will still be delicious!
- Tomatoes - this recipe is great with cherry or grape tomatoes but I'm thinking any small type of tomatoes will work like campari or cocktail tomatoes. I would suggest going with organic if budget allows and avoiding triple washed tomatoes (usually bought in containers in stores) as these lack natural microbes found on the surface of vegetables.
- Fresh herbs: tone down the pickling spice (or omit all together) and add fresh herbs like basil, dill, parsley, oregano, and thyme for different flavors.
- 🕐Time Saving Tip: use warm water to create the salt brine as it will help dissolve salt faster
- 💲 Money Saving Tip: preserve your abundance of cherry tomatoes to enjoy them in colder seasons when fresh tomatoes are at a premium
- 🗓Brine Tip: enjoy the extra brine in salad dressings or used as a starter culture for future ferments.
- 🚫Food Safety: Never eat anything with mold growing on it. Toss the food immediately if you see any kind of mold growth that looks fuzzy, pink, blue, or green. Kahm yeast, appears like a crinkly white film on top of the brine, is a common and harmless growth on many lacto-fermented veggies.
💭Good to Know: Skip the plastic and use glass jars as your fermentation vessel to avoid any BPAs leaching into your ferment.

This Fermented Tomatoes recipe calls for these ingredients that you will need: cherry tomatoes, pickling spice, sea salt, and warm water.
Step 1. Make salty brine
Dissolve salt in a cup of warm water. The best way to do this is in pint size mason jar as it already has cup measurements on the side.
💭Helpful Tip: Used boiled water to make sure it's sterilized. Gently warmed water from tea kettle is great for this purpose!
Step 2. Prepare tomatoes
Add pickling spice and garlic cloves to the bottom of a wide-mouth mason jar or weck jar. A quart-sized jar is ideal to avoid any spillage from the fermentation process.
Add washed and dried tomatoes. Pour salty brine (make sure it's not too warm to touch) over the tomatoes.
Place the fermentation weight over the tomatoes to keep them submerged. Set aside to ferment at room temperature away from direct sunlight. It's helpful to have the tomatoes on a small plate to collect any excess brine that may spill over from the carbon dioxide if the brine comes too close to the top of the jar.
Step 3: Ferment
During the first 5 days of fermentation, gently open the jar lid to release carbon dioxide.
After about 10 days of room temperature fermentation, the brine should become cloudy and bubbles should disappear. At this time, they are fermented and can be transferred to the refrigerator.
💭Did you know? As the tomatoes ferment, the brine will change from clear to cloudy. This is the natural growth of beneficial bacteria.

These little nuggets of flavor are good on just about anything. Enjoy them tossed in a salad, on a slice of crusty buttered sourdough, or over fish or chicken.
After the initial fermenting period at room temperature, keep your fermented tomatoes in a dark, cool storage like the refrigerator for up to 6 months.
It is not necessary to keep the fermentation weight in there once the tomatoes have been transferred to the refrigerator.
Depending on your room temperature, it should take anywhere between 8-14 days for your tomatoes to be fully fermented. You want to look for a cloudy brine and no more gasses to be released when opening the jar. After this time, transfer the tomatoes to your refrigerator.
No! All that is needed is a jar with lid and a fermentation glass weight to keep tomatoes fully submerged in the salty brine.
Fermented tomatoes that are properly prepared and stored in a dark, cool storage like the refrigerator can be good for 4-10 months. I don't recommend going past 6 months though as the tomatoes may loose texture and full probiotic health benefits.
