How to Make a Japanese Nuka Zuke Pickle Bed

Looking for a new way to ferment vegetables?  Something quick and easy to make fermented pickles that are a great condiment to any meal.  A Nuka bed offers a way to get lactobacillus bacteria and wild yeast, without having to vent or clean up exploding glass jars!  It makes a great RAW, fermented/cultured, and vegan condiment.

NUKA BED

What is a Nuka ‘Bed’?

Nukazuke (糠漬け) are a type of Japanese pickle, made by fermenting vegetables in rice bran (nuka). Almost any edible vegetable may be pickled through this technique, though traditional varieties will include eggplant, Japanese radish (daikon), cabbage, and cucumber. The taste of nuka pickles can vary from pleasantly tangy to very sour, salty and pungent. These pickles also retain their crispness which adds to their popularity.

Fish nukazuke is also common in the northern part of Japan. Sardines, mackerel, and Japanese horse mackerel are frequently used. Some people pickle meat in nuka-bed, too.
If pickling meats, use a separate nuka bed and not the bed for vegetables.

The nuka-bed is traditionally kept in a wooden crock but ceramic crocks or even plastic buckets are also common. Many Japanese households have their own nukazuke crocks which are faithfully stirred by hand every day. Due to varying methods and recipes, flavors vary considerably, not only from region to region, but also from household to household.

Pickles (tsukemono) are an important staple of Japanese cuisine, and nukazuke are one of the most popular kinds. They are often eaten at the end of a meal and are said to aid in digestion. The lactobacillus in nukazuke pickles may be a beneficial supplement to the intestinal flora.  They are also high in vitamin B1.

Japanese Pickles Ready to Eat

Needed Ingredients…

–  Rice Bran, no-GMO and/or organic
–  Kombu Seaweed – cut into very small pieces
–  Sea Salt
–  Korean Chili Flakes
–  Dried Citrus Peel
–  Dried Bonito Flakes – Optional
–  Condiments of your choice

Directions…

Note: It needs to be stored under refrigeration after opening to avoid rot.  Storage term: 12 month (This usable time is only a guide. If you stir well NUKA-BED with your hand once every 2-3 days, add extra NUKA rice bran and salt as necessary, it can be used semi-permanently.)

If you are using the nuka kit purchased from us, you will receive two packets.  The larger pack is the rice bran and flavorings.  The smaller packet is the Nuka starter with fresh sliced fruit.

1.  Start by opening the large packet or mixing the above ingredients together and adding enough filtered water (no city tap water please) to make a thick paste.  Add the water in small amounts until the correct thickness is obtained.  Over time, the addition of the vegetables will add water to the mixture and more fresh rice bran will be needed.

2.  Now add the small packet that contains the nuka starter and fresh fruits.  If making your own nuka bed, just add some slices of fresh cut organic or wild apples.  Mix in the nuka starter by hand until well blended.  Also, when starting a new nuka bed from scratch,  it will take time for the bacteria and yeast to grow through the bed and become 100% active.

3.  Add the vegetables that you wish to pickle.  Common choices are roots like burdock and carrots, small eggplant, Japanese radish (daikon), cabbage, and cucumber.  We like doing radishes and cucumber!
Rub the vegetables with sea salt then place into the nuka vessel pushing them down to cover with the rice bran mixture.

4.  Allow the vegetables to sit in the nuka bed for 3 to 5 days. Culturing time may vary depending on the vegetables used and temperature.  The taste will move from tangy to very sour the longer the pickles set in the nuka.  Do not ferment at room temperature during the hot summer months or the bed may become contaminated with molds.

Hand Mixing NUKA-BED
Daily Hand Mixing nuka bed

Mix by hand each day making sure to replace the vegetables under the rice bran.  Salt may be sprinkled over the top to help retard mold growth, too.  Once complete and to your liking remove the nuka pickles, slice, and serve.  Start a new batch or place fermenting vessel in the refrigerator keeping it mixed to prevent mold growth.

Enjoy this method of making great quick pickles without the mess of multiple jars, airlocks, weights, and other unnecessary items.  The taste and flavor of the cultured nuka vegetables is second to none!  If you want a premixed nuka bed, we have them available in traditional or vegan, at our web store – store.organic-cultures.com

Happy Culturing!
