Fermented Root Vegetables With Whey for GAPS

Fermented root vegetables bring a sour, garlicky crunch to a meal. This medley combines radishes, daikon, carrots, and turnips with ginger, onion, mustard, coriander, and bay. Homemade cultured whey is the starter for this version, with a small measured amount of salt for the complete batch.

Plan on about three quart jars and at least a week of fermentation, with more time if the vegetables need it. The important kitchen jobs are cutting the roots, mixing and dividing the ingredients, keeping everything below the liquid, and checking how the flavor and texture develop.

Jump to the Recipe

Our home ferments are sauerkraut, kimchi, and fermented kimchi hot sauce, and I am still experimenting with more. With homeschooling before second shift, I appreciate knowing which preparations need attention now and which mostly need time. A dated start and a quick daily check make that waiting time easier to organize.

Prepare the Whey Before You Start

Measure three-quarters of a cup of whey drained from homemade 24-hour GAPS yogurt. Have the finished liquid ready before packing the vegetables. Making and draining the yogurt is separate preparation, so its time is not included in the vegetable recipe’s half-hour preparation estimate.

The whey should come from completed cultured dairy. Whey protein powder is a different product. So is liquid from milk that was heated and acidified without live cultures. This recipe uses the clear, yellowish liquid collected from the homemade yogurt preparation.

This is a dairy-containing version. Fermenting the vegetables does not change that ingredient fact. Keep the name of the starter with the recipe so everyone choosing from the jars knows which preparation you made.

Roots, Aromatics, and Seasoning

Radishes: Trim a bunch of colorful radishes and cut them into quarters. Cut a large daikon into slices. The colored radish skins can gradually tint the liquid pink; the daikon begins much paler. Start with fresh, firm roots and cut away damaged parts.

Carrots and turnips: Slice a bunch of carrots. Peel and chop enough turnip to measure one cup. Make the pieces manageable to eat rather than leaving very large chunks beside thin carrot slices.

Garlic, ginger, and onion: Crush six peeled garlic cloves. Peel and dice a three-inch piece of ginger, then thinly slice half an onion. These are spread through the batch so one jar does not receive all the strong aromatics.

Mustard, coriander, and bay: The batch uses two teaspoons of mustard powder, two teaspoons of pure ground coriander, and three bay leaves. Mix the powdered seasonings through the vegetables before dividing them. Distribute the bay leaves among the jars.

Salt and water: One tablespoon of natural sea salt is for the entire batch. Start with three cups of filtered water, roughly a cup for each intended jar, with more cool filtered water as needed to cover. Mix the measured salt into the starting water once; do not add another tablespoon to each jar.

How to Pack the Vegetable Jars

Cut and Mix the Vegetables

Wash the roots and prepare their different cuts. Combine them with the garlic, ginger, onion, mustard, and coriander in a roomy bowl. Turn the mixture from the bottom so the seasonings and different roots are distributed rather than layered into separate vegetable jars.

Bunches and daikon vary in size. Three quart jars are the intended starting setup, not a promise that every bunch will fill them identically. Have another clean jar available if needed to keep the vegetables submerged with enough space above the liquid.

Mix the Starter Liquid

Dissolve the tablespoon of salt in the starting water. Stir in the measured cultured whey once the water is cool. If you warm any water to help dissolve salt, let it cool completely before adding whey or pouring it over the vegetables.

The starter and salt amounts are measured for the whole batch. Divide the mixed liquid along with the vegetables rather than pouring all the whey into the first jar and leaving plain water for the last one.

Keep the Pieces Below the Liquid

Pack the mixture into clean wide-mouth quart jars, pressing it down to remove large gaps. Add the starter liquid and enough extra cool filtered water to cover. Keep about two inches of clear headspace at the top, allowing room for the vegetables and liquid to rise as gas develops.

Use clean glass fermentation weights to hold the roots below the liquid. Check the small onion and ginger pieces as well as the larger radish quarters. A large piece sitting under the weight does not help a handful of little pieces floating above it.

Stand the jars in a tray. Fit pressure-releasing fermentation lids, following their instructions. If using ordinary screw lids, briefly loosen them to release pressure daily during the most active first few days, then close them again and continue checking as activity slows. This releases gas; it is not a step for airing out or stirring oxygen into the vegetables.

Allow a Week or Longer

Keep the jars at room temperature away from direct sunlight. For this GAPS preparation, allow a week or longer. Cooler conditions slow the changes; warmth speeds them up. The recipe card shows a week as the minimum planning allowance, with preparation time added separately.

You may see small bubbles around the roots, cloudy liquid, or sediment settling below them. You may also notice very little visible bubbling. Sandor Katz describes vegetable ferments that develop without obvious bubbles, so a lack of fizz alone does not decide whether a jar has changed.

After the planned week, check the flavor and texture with a clean utensil. The roots should be distinctly sour, with the garlic, ginger, and mustard still noticeable. They should keep some bite rather than being expected to become cooked-soft on the counter. Give them more time if the flavor has not developed.

A dated note helps with jars that started on different days. My planned Ferment Tracker is a fit for keeping those starts and checks together. The date is a useful reminder to look at the food, not a substitute for checking the actual jar.

Where This Fits on GAPS

The completed vegetables fit Full GAPS. The Introduction Diet distinguishes how fermented vegetables are used. Earlier Intro begins with small amounts of juice from a completed vegetable ferment, added when the soup or chicken meat stock is no longer too hot for the culture.

Dr. Natasha’s 2020 book also allows fermented vegetables cooked very soft in first-stage soup. That cooked use is separate from eating these cold, crunchy pieces. Uncooked fermented vegetable solids are introduced gradually at Stage 3, following the juice introduction.

Because this version contains whey, dairy introduction matters too. Use it once that cultured dairy form has been introduced. For a dairy-free ferment already in the kitchen, the green sauerkraut uses cabbage and salt without whey.

The roots, onion, and spices make this a vegetable preparation, so it does not fit No-Plant GAPS.

Storage and Serving

When the sourness and texture are ready, cover and refrigerate the jars with the vegetables still beneath the liquid. Cold storage slows continued fermentation. Use clean utensils, then return the weight or repack the remaining pieces below the brine.

Keep the liquid with the vegetables instead of draining the whole jar for storage. Small servings taken from the top should not leave the remaining roots exposed. Check the level again after you remove a portion.

On Full GAPS, a small serving can sit alongside skillet chicken with basil walnut pesto. It gives you a cold, sour vegetable condiment beside the cooked chicken. Follow the separate chicken recipe’s stage and dairy notes as well.

Frequently Asked Questions

Is the Tablespoon of Salt for Each Jar?

It is for the complete batch. Dissolve it in the starting water and divide the mixed liquid across the vegetables. Adding a tablespoon to each of three jars would triple the recipe’s salt.

Does No Bubbling Mean Nothing Happened?

No. Visible bubbles vary. Look at the developing sourness and texture along with the fermentation time, and keep the roots submerged. Katz notes that bubbles can be imperceptible in vegetable ferments.

What If a Surface Film Develops?

Katz’s method removes surface growth promptly rather than stirring it into the vegetables. Gently lift the weight, skim the surface, and remove any dry, discolored, or softened top pieces. Keep the remaining vegetables below the liquid and replace the clean weight.

Can I Use Whey Powder?

Use live cultured whey drained from the completed homemade yogurt. Protein powder is not that starter ingredient. Prepare enough liquid whey and measure it before starting the jars.

Equipment for the Batch

Have clean wide-mouth quart glass jars, glass fermentation weights, suitable lids, a tray, a large mixing bowl, and a measuring jug ready. A knife and stable board handle the different root cuts. No cooking pan or blender is needed for packing this ferment.

Choose enough jar space to preserve the headroom and submersion. An airlock-style fermentation lid releases gas without repeated lid opening; ordinary screw lids need the brief pressure-release checks described above. Follow the lid’s actual instructions.

The planned Crock & Jar: Ferments for GAPS Families course and Kid-Friendly Ferments Recipe Card Deck are part of the WFLI course and cookbook catalog. Have the whey collected and the jars ready before cutting the vegetables, then keep the start date with the batch.
