Mason Tops Fermenting Recipes for Crunchy Pickles

Mason tops are one-piece silicone lids that let fermentation gases escape from a wide-mouth Mason jar while keeping vegetables submerged under a weight. Use them to make a small batch of tangy, crunchy garlic-dill cucumber pickles with a simple salt brine; the method is hands-off, but the jar needs daily attention and a cool place to ferment.

Ingredients

1½ lb (680 g) small pickling cucumbers, rinsed and trimmed
2 cups (480 ml) nonchlorinated water, plus more as needed
1 tbsp plus 1 tsp (24 g) fine sea salt or pickling salt
4 garlic cloves (about 20 g), peeled and lightly crushed
2 tsp (4 g) whole black peppercorns
2 tsp (2 g) dill seed
4 fresh dill sprigs (about 8 g)
1 grape leaf (optional; about 2 g), rinsed
1 wide-mouth quart (946 ml) Mason jar, fitted with a Mason top and fermentation weight

Instructions

Wash the jar, lid, weight, and utensils thoroughly with hot, soapy water and rinse well. Clean equipment helps prevent unwanted contamination, but it does not make the ferment shelf-stable. Use a sound jar without chips or cracks. Wash your hands, cucumbers, dill, and grape leaf.
Stir the salt into the 2 cups (480 ml) water until dissolved. This makes a brine of about 5% salt by volume, appropriate for this cucumber batch. If your tap water is strongly chlorinated, use filtered water or water labeled nonchlorinated; chlorine can interfere with fermentation.
Pack the cucumbers snugly into the jar, standing them upright when possible. Tuck in the garlic, peppercorns, dill seed, dill sprigs, and optional grape leaf. Leave about 1½ inches (4 cm) of space at the top so the weight and brine fit without overflowing.
Pour in the brine until the cucumbers are covered. Set the fermentation weight on top. Every cucumber should remain below the liquid; add a little more prepared 5% brine if needed rather than plain water. Fit the Mason top according to its manufacturer’s directions, making sure the vent is unobstructed. Put the jar on a plate or shallow tray to catch any overflow.
Leave the jar at 65–70°F (18–21°C), away from direct sunlight, for 5 days. Check it daily: confirm the vegetables remain submerged, remove any debris from the jar rim with a clean utensil, and make sure the lid’s vent is clear. Bubbles, a cloudy brine, and a pleasantly sour smell are normal signs of active fermentation. Do not tightly seal the jar with a standard lid during this stage; gas must be able to escape.
After 5 days, taste a slice using a clean fork. If it is tangy enough for you, remove the weight, close the jar with a clean storage lid, and refrigerate. If you prefer a stronger sour flavor, continue fermenting and taste daily, keeping the cucumbers submerged. Fermentation time varies with room temperature, cucumber size, and personal taste; refrigerate promptly once the flavor is right.

Tips

Use pickling cucumbers that are firm and small enough to pack tightly. Trim only the blossom end, which can contain enzymes that soften pickles; trimming both ends is fine if you are unsure which end is which.
Use pickling salt or fine sea salt without iodine or anti-caking additives when possible. Coarse salt is harder to measure by volume, so weigh it; the 24 g quantity is the more reliable measure.
The grape leaf is optional. Its tannins may help the pickles stay crisp, but it is not essential; a clean oak leaf is a traditional alternative, while omitting leaves may produce a slightly softer result.
Do not eat pickles with fuzzy mold, a rotten or putrid odor, or an unusual slimy texture. A thin white film can sometimes form on the surface, but when uncertain, discard the batch rather than tasting it.

Serving Suggestions

Serve the chilled pickles alongside sandwiches, burgers, grilled cheese, or a plate of beans and roasted vegetables. Slice them into potato salad, chop them for a relish-style topping, or add a few spears to a cheese board. Their salty, sour flavor is concentrated, so taste before adding extra salt to the rest of the meal.

Variations

For a spicier jar, add ½ tsp (1 g) red pepper flakes or one small dried chile. For a stronger garlic-dill profile, add two more crushed garlic cloves or an extra dill sprig. You can replace some of the peppercorns with 1 tsp (2 g) mustard seeds or coriander seeds. Keep the salt and water proportions unchanged when changing herbs and spices; avoid adding vinegar, which changes this from a naturally fermented pickle into a different method.

This brine can also be used with firm green beans or carrot sticks, but they ferment at a different pace and may need longer than cucumbers. Cut them into pieces that fit below the weight, keep them submerged, and taste daily after the first few days. Do not assume another vegetable is ready on the cucumber schedule.

Storage and Reheating

These are refrigerated fermented pickles, not shelf-stable preserves. Once the flavor is right, refrigerate the jar within 2 hours; keep it at 40°F (4°C) or colder, with vegetables covered by brine, and use a clean utensil each time. For best quality, use within about 1 month. Discard them sooner if mold, a rotten smell, or marked sliminess appears. Do not store the jar at room temperature after fermentation, and do not use this recipe for canning. Pickles are served cold, so reheating is not needed.

Frequently Asked Questions

Do Mason tops work with any Mason jar?
Check the lid manufacturer’s directions. Many Mason tops are designed for wide-mouth jars, but openings and fittings vary. Use the matching jar size, fermentation weight, and lid parts, and leave adequate headspace.

Do I need an airlock?
A Mason top with a functioning one-way vent can release fermentation gas without a separate airlock. Follow the product’s fitting instructions. A regular airtight canning lid is not a substitute because pressure can build up as the vegetables ferment.

Why are my pickles soft?
Softness can come from old or oversized cucumbers, warm fermentation, uncovered vegetables, or leaving the batch fermenting too long. Use very fresh cucumbers, trim the blossom ends, keep the jar cool and the vegetables submerged, and refrigerate when the flavor suits you.

Is cloudy brine a problem?
Cloudiness and bubbles are common during lactic fermentation and are not, by themselves, a reason to discard the batch. Check for a clean, sour smell and normal texture, and watch for the warning signs in the tips section.

Can I use iodized table salt?
It will make the brine salty, but additives may cloud it and fine crystals are easy to mismeasure by volume. Pickling salt or fine sea salt is preferable; weighing 24 g gives a more consistent result.

Can I reuse the brine for another batch?
It is better to make fresh measured brine for each batch. Used brine has an unpredictable salt concentration and microbial balance, so it may ferment differently. You can use a small splash of finished brine to season a dressing, but keep it refrigerated.
