Mixed Vegetable Preserve in Sweet-Sour Brine
A mix of onion, green tomato, cucumber, and bell pepper in a sweet-sour vinegar brine, canned for winter storage — a Central European preserving classic.
Quick Summary
A mix of onion, green tomato, cucumber, and bell pepper sliced thin, briefly cooked in a sweet-sour vinegar brine, then sealed in jars for winter storage. A cool, dark storage spot is essential for safe keeping.

Additional notes
-
Warning
This is a sealed jar preserve intended for long-term storage. Jars and lids must be properly sterilized, and the filled, sealed jars must be processed in a boiling water bath for the full time given, to make the preserve safe for room-temperature storage. Do not skip this step.
-
Caution
Sealed jars must be stored in a genuinely cool, dark place, such as a cellar or unheated pantry, for the winter storage period this recipe is intended for. Warm storage conditions can allow spoilage even in a properly processed jar.
-
Note
This preserve is high in sodium (339mg per 2-tablespoon serving) due to the amount of salt used in the brine. Those managing sodium intake may want to enjoy it in smaller portions or rinse briefly before serving.
- 1
Wash all the vegetables. Peel and thinly slice the onions; thinly slice the green tomatoes, cucumbers, and bell peppers into rounds.
- 2
In a large pot, combine the 3L wine vinegar, 500ml oil, 400g sugar, 350g salt, and 28g whole peppercorns. Bring to a boil over medium-high heat.
- 3
Once the liquid is boiling, add all the sliced vegetables to the pot and cook for 3 minutes.
- 4
Remove the pot from the heat and let the mixture cool completely, about 90 minutes, before packing into jars.
- 5
While the vegetables cool, sterilize the jars and lids by boiling them in water for at least 10 minutes. Keep them hot until ready to fill.
Tip Proper sterilization and processing are essential here — this recipe is meant to be stored at room temperature over the winter, and skipping this step creates a real food safety risk. - 6
Once the vegetable mixture is completely cool, pack the vegetables and their liquid into the sterilized jars, leaving about 1cm of headspace, and seal with the lids.
- 7
Process the filled, sealed jars in a boiling water bath for 15-20 minutes to make them shelf-stable.
- 8
Remove the jars carefully and let them cool completely on a towel-lined surface, undisturbed. Check that each lid has sealed properly (the center should be pulled down and not flex when pressed) before storing.
- 9
Store sealed jars in a cool, dark place. Once opened, refrigerate and use within a few weeks.

Serving Suggestions
Serve cold or at room temperature, straight from the jar, as a side to grilled or roasted meats. As the traditional approach notes, this preserve is meant to be enjoyed on its own, without any further additions or dressing.
About This Recipe
This is a preserve built for volume — eight kilograms of vegetables between four kinds, cooked briefly in a sweet-sour vinegar brine and sealed away for the colder months. It’s less a recipe for a single meal and more a project for a weekend, the kind of thing a household would put up in late summer when green tomatoes, cucumbers, and peppers were all available at once, to be opened jar by jar once fresh vegetables became scarce.
The short cooking time — just three minutes once the brine boils — keeps the vegetables from turning fully soft, so what comes out of the jar months later still has some bite to it, closer to a pickle than a cooked relish.
Why It Works
The vinegar in the brine does most of the preservation work by lowering the pH of the finished product enough to inhibit the growth of most spoilage organisms, while the salt and sugar both help draw moisture out of the vegetables and further discourage bacterial growth. Cooking the vegetables only briefly, just three minutes, keeps them from breaking down completely, so they hold their shape and some crunch through months of storage rather than turning mushy. Cooling the mixture fully before jarring, rather than packing it in hot, prevents the vegetables from continuing to soften from residual heat while sealed.
Modern Kitchen Tips
Slice the vegetables as evenly as possible — a mandoline speeds this up considerably given the volume involved here. Layer the different vegetables somewhat evenly across jars rather than filling one jar with mostly onion and another with mostly pepper, so each jar gives a balanced mix when opened. Label jars with the date before storing; a preserve like this is best used within about a year.

The Story Behind This Recipe
Historical Context
Early 20th century recipes for this kind of winter preserve relied on vinegar, salt, and sugar for preservation, with the vegetables briefly cooked in the boiling brine before jarring. The traditional approach did not describe sterilizing the jars or processing them after sealing — a home cellar's naturally cool, stable temperature, combined with the acidity of the vinegar, was relied upon to keep the preserve safe through the winter months.
Modern Kitchen Adaptation
Jar and lid sterilization, along with a boiling water bath processing step after sealing, have been added to this recipe. These were not part of the traditional approach, but they are necessary for safe, reliable long-term storage at room temperature by modern food safety standards, regardless of how acidic the brine is. This preserve still requires storage in a genuinely cool, dark location, such as a cellar or unheated pantry, for the full winter storage period the recipe describes — it is not suited to being kept in a warm kitchen cupboard or a small apartment without a cool storage space. The peppercorn quantity and jar yield are estimated, since the traditional approach measured pepper by its cost rather than its weight.
