Wine Vinegar
Wine vinegar is made by the aerobic oxidation of wine's alcohol into acetic acid by bacteria, producing a sour, wine-derived condiment used in dressings, sauces, marinades and preserved foods.
Ajvar-style roasted pepper relish
A small roasted red-pepper and eggplant relish with sunflower oil, wine vinegar, garlic and salt. It is a modern ajvar-style trial, not a validated winter preserve or a copy of a commercial formula.

Ajvar is made in many household and commercial forms across the Balkans. FAO describes Macedonian pepper processing: peppers are roasted, peeled and cooked further with salt and oil; families vary the additions, sometimes using tomato, carrot or roasted eggplant. The word therefore names a family of pepper preparations rather than one fixed formula. This small batch uses red pepper and eggplant, with sunflower oil, wine vinegar, garlic and salt.
That distinction matters when comparing recipes. The linked Ajvar page documents a separate, much larger family batch and its historical and regional forms. This record keeps a smaller modern trial distinct: the measured formula comes from an archive-developed prototype, not from a source's traditional recipe, and the method has not been kitchen-tested. Its link to Ajvar says that the relish belongs to the same preparation family; it does not claim a Leskovac designation, a Macedonian household lineage or a tested commercial formula.
Roasting softens the pepper flesh and loosens its skin. Turning the vegetables exposes their surfaces to the oven heat; the target stated by the formula is blistered skin with softened flesh, not a calibrated internal temperature. Covering warm peppers for a short rest lets steam loosen the skin so it can be peeled away. Removing seeds and draining the flesh before weighing keeps loose liquid from simply being carried into the pan.
Cook the eggplant until tender and scoop out the flesh rather than measuring it raw. The recipe specifies 220 g of prepared pepper flesh and 45 g of cooked eggplant flesh. Those weights describe the material after its separate cooking and draining stages; they are not the weights of the raw vegetables to buy. Once weighed, the two cooked vegetables are minced or pulsed with the measured oil, vinegar, garlic and salt.
The final simmer concentrates the mixture as water evaporates. Stirring often helps keep the thickening paste moving across the pan rather than sitting in one hot spot. The source gives a 15–25 minute window and a spoonable texture cue, but not a final temperature, fixed evaporation rate or measured endpoint. A wide pan, the moisture left in the vegetables, and the size of the pieces all affect how quickly it thickens. The stated time is the archive's formula instruction, not a general Ajvar cook time.
This is a fresh cooked relish, not a winter preserve. The formula has no measured pH or water activity, microbial testing or validated heat process. A small amount of wine vinegar and a simmer add acidity and remove some water, but neither a sour taste nor a thick texture demonstrates that the relish can be kept at room temperature. The recipe therefore makes no canning or shelf-life claim.
Use the refrigeration instruction as a handling control: place the cooked relish promptly in a shallow clean container, refrigerate it within two hours, and keep the refrigerator at or below 40°F (4°C). FoodSafety.gov explains the two-hour rule and shallow-container cooling for leftovers. The National Center for Home Food Preservation explains that even for salsa, safe home canning depends on a research-tested formula and its stated vegetable-to-acid proportions. That guidance is not a canning method for this ajvar-style relish; it is why no process has been borrowed from a different food.
The formula's yield is estimated at 300 g before the last simmer. Evaporation lowers the finished amount, and the record gives no scale-up evidence or storage duration. Freezing may be considered for a fresh portion if its texture change is acceptable, but no duration or quality result has been tested for this specific mixture.
The formula starts with 220 g of prepared roasted red pepper and 45 g of cooked eggplant, a ratio of about 4.9 parts pepper to one part eggplant by weight. It adds 25 g sunflower oil, 7 g wine vinegar, 1 g minced garlic and 2 g salt. These are the quantities in the archive's own prototype. They are not measured out of a source recipe, and the page does not suggest changing them to make a pantry preserve.
Podravka's mild ajvar provides a useful commercial comparison, not a template: the current label lists 76% pepper, 12% eggplant, sunflower oil, alcohol vinegar, 2.6% tomato concentrate, salt, sugar, spices and hot feferon. The pepper-to-eggplant ratio on that label is about 6.3 to one. The home prototype is more eggplant-heavy by this simple comparison, adds garlic and wine vinegar, and omits tomato concentrate, sugar, spices and feferon. It is related by ingredient family, not a copy of the product or a reconstruction of its proportions.
The official product page describes the commercial blend's ingredients and uses but does not provide a home method or a tested small-batch conversion. The figures here describe a single untested trial. They should not be scaled by multiplying every line: a larger quantity changes how quickly a pan sheds moisture, how much surface area is exposed to heat and how long the mixture takes to concentrate.
Prepared red pepper supplies most of the mass and the recognizable red color. Roasting gives the flesh the cooked flavor associated with Ajvar and softens it enough to peel, grind and reduce. The FAO account documents roasting, peeling and further cooking as central steps in Macedonian pepper processing; this prototype uses those broad operations but sets its own weights and seasoning.
Cooked eggplant is a smaller but substantial part of this version. It makes the mixture less purely pepper-based and contributes soft flesh that can be pulsed into the spread. FAO notes eggplant as one of the additions some Macedonian families use, while the Leskovac protected specification sets out its own pepper-focused ingredient identity. That contrast shows why eggplant belongs to some Ajvar forms but cannot be assumed in every one.
Sunflower oil is incorporated gradually with the ground vegetables and gives the paste a smooth, glossy mouthfeel. The measured wine vinegar brings a tart note, but its 7 g quantity is not an acidification calculation. Garlic adds a savory aroma; salt seasons the vegetable mixture. None of these sensory roles establishes a fermentation stage or a safety endpoint. The recipe is cooked and non-fermented, and its texture cue is for eating quality only.
Ajvar is often introduced as a Balkan preserve, but household practices and commercial definitions vary by place and period. Miladina Monova's study follows Macedonian household cooking and its changing social context. It describes collective work around seasonal peppers and the role of preserving in household provisioning; it does not establish one national recipe or give the weights used here. The exact small-batch formula in this record has no independent historical attestation.
FAO's account of Macedonian peppers focuses on processing and the crop's place in food practice. A different regional reference, the Leskovac product specification, defines a protected local product through its own area, ingredients and operations. Its name applies to that specific designation, not to every pepper relish called Ajvar. This page links to the broader Ajvar record so readers can follow its sourced history and regional distinctions without mistaking this trial for one of them.
The link is a classification of relationship, not a claim of origin. This version is a contemporary kitchen-scale adaptation, with vinegar and garlic in a small formula and a refrigeration-only handling instruction. No source found for it describes a traditional family, protected product or place of invention.
Ajvar is used as a spread, relish or side dish. Podravka lists grilled foods, sandwiches, sausages, sauces, stews and soups among uses for its mild commercial product. Serbia's National Tourism Organisation describes it served with scrambled eggs and white cheese. These examples show how Ajvar can move from bread or a side plate into a cooked dish, but they do not prescribe a serving for every regional type.
This prototype's roast pepper and eggplant base suits bread, sandwiches or a small side portion. Because the garlic and vinegar quantities differ from commercial examples, its flavor should be described as this formula's own rather than as a universal Ajvar taste. The record does not establish an adjustment range; changing pepper type, eggplant ratio, oil, vinegar or salt would create a new formulation, and changing acid or vegetables would also change what could be said about preservation.
A small batch makes sense for trying the texture and seasoning while it is fresh, but it is not evidence of safe storage. The final amount varies as water leaves the pan, so serving portions should be based on the finished relish rather than the 300 g pre-simmer estimate.
The steps preserve what the formula actually specifies: roast, cover, peel, remove seeds, drain, measure the cooked flesh, mince or pulse, and simmer with frequent stirring. Roasting time is left to the physical cues in the instructions because the source gives no duration. The final simmer has a source-batch window, but no numerical temperature or final concentration. A spoonable consistency means the mixture has thickened to the desired texture; it does not show that an acidified or shelf-stable product has been made.
Ajvar production can demand long, steady cooking in larger household and commercial batches. That experience helps explain why stirring and water removal matter, but it cannot be transferred as a fixed two-hour rule to this smaller pan. The family formula elsewhere on the Ajvar page uses ten kilograms of peppers and reports roughly two hours of cooking; this trial starts with 265 g of prepared vegetable flesh and simmers for 15–25 minutes. The scale, vessel, raw material and process differ, so the timings should remain separate.
Where a preservation process is absent, the honest result is a fresh cooked relish with no established storage period. Do not infer shelf stability from vinegar, oil, salt, a reduced texture or a sealed container. Keep this formula refrigerated as directed and do not use it as a canning recipe. A tested process for another vegetable mixture cannot validate this one by resemblance.
The ingredient line names red peppers and eggplant but does not specify a cultivar, growing region or raw purchase weight. It gives weights for the cooked flesh after roasting, peeling and draining. That choice makes the formula repeatable at the stage it measures, while leaving the amount of raw produce needed open: different peppers shed different amounts of water and skin, and the eggplant flesh is weighed only after cooking.
The official Leskovac specification is more specific about its own regional product and its pepper varieties. Those details help explain what a protected local identity can mean, but they are not requirements for this home-style trial. Likewise, FAO's account records several Macedonian family additions, but it does not establish a universal list or endorse a particular proportion for this formula.
Do not assume that any change named in another Ajvar recipe fits these quantities. A different pepper, eggplant amount, chilli, tomato, vinegar or oil would change the composition and the eating result. The base formula is retained as written; this record has no tested substitution range. Its name signals a modern relish inspired by Ajvar, and the existing variant link points to that broader preparation without claiming that the two recipes are interchangeable.
Ajvar is made in varied Balkan household and commercial forms. FAO describes Macedonian pepper processing and notes that families differ in additions, including roasted eggplant. Podravka's commercial roasted-pepper ajvar lists pepper, eggplant, oil, hot pepper and salt. This small batch adds wine vinegar and garlic and is a modern untested adaptation, not a traditional or preserved formula.
