Sauerkraut

I have served variations of this fermented cabbage at multiple feasts, including Ymir 2019 and Ymir 2025. The core idea — a salt-fermented cabbage as a plausibly-period “sour cabbage” rooted in the Domostroi — has stayed constant across versions; the specific additions have varied.

What, Where, When

• A salt-fermented cabbage with leek and thyme, loosely modeled on the “sour cabbage” frequently mentioned in the Domostroi.
• Core attestation: cabbage fermentation in brine as a Rus staple. Conjectural additions: leek and thyme, and a small vinegar kickstart.

Discussion

Sour or fermented cabbage appears repeatedly in the Domostroi, a mid-16th century Russian household management text, as a staple component of fast-day and everyday meals. Pickled cabbage in brine was widespread in Rus households, both as a subsistence preservation method and as a feature of regular cooking. What the Domostroi does not provide is a recipe: we know cabbage was fermented, we do not know what else (if anything) went into the crock with it. This recipe is therefore a plausible construction built on a solid attestation — the fermented-cabbage-as-staple claim is well-supported; the specific additions are named conjectures rather than documented period practice.

Three choices are mine rather than the source’s:

• Leek is added for flavor and aromatic complexity. Alliums of various kinds were available and in use in period Rus cooking; leek specifically in a cabbage ferment is my interpolation, not a period attestation.
• Thyme is the most obviously non-documented addition. It reads as a flavor choice rather than a period-authenticating one; I used it because it works, not because I can defend it from a source. A strict reading of the evidence would leave it out.
• A small amount of apple cider vinegar is added at the start as an acid kickstart — roughly 2 tablespoons per 3 pounds of cabbage. A properly salted cabbage ferment will acidify on its own given time, but the vinegar speeds the initial drop in pH and nudges the microbial population toward the right kind of fermentation from the beginning. It is a modern hedge against an inconsistent outcome. The primary acidification is still lactic, from salt fermentation over several days.

A note on the cabbage itself: at Ymir 2025 I had to substitute red cabbage for roughly half the intended green, because a snowstorm cleared out the grocery store and I could not get enough green cabbage. The red cabbage seemed to release less liquid during salting, which left the salt unevenly distributed through the bucket — some diners found the kraut very salty, others found it well-seasoned. If you are making this for a specific occasion, stick with all green cabbage if you can.

The version below is the Ymir 2025 formulation — cabbage with leek, thyme, and a vinegar kickstart. The Ymir 2019 version used grated carrot instead of leek (roughly one part carrot to three parts cabbage) and no vinegar at all; I relied entirely on salt fermentation and it worked fine. The carrot version reads noticeably sweeter than the leek version, which is worth knowing if you are choosing one to serve alongside specific other dishes. Either version is a reasonable starting point. The vinegar kickstart is a hedge rather than a requirement.

Sources

The Domostroi mentions sour cabbage in multiple dietary listings — enough that no single quoted passage represents the source’s position. The text treats fermented cabbage as a default condition of a well-stocked household rather than a dish requiring a recipe.
