Sour rolled oats soup with whye and shiitake - Żur owsiany



Last week I experimented again with sour starters, homemade curd and sour cabbage. Working on all these in a 5 square meter kitchen requires some sort of courage. Every preparation takes time and place: another challenge is to find enough storage for all this food in such a tiny surface.
I found that the best place for a good fermentation of the sour starters is on top our laundry dryer. As to the jar of sour cabbage, it has found its place on the floor, under a small table, where it is protected from the day light. Two other bowls with sour milk were placed on the top of the washing machine, which is close to the window but not exposed to the sun. Thanks to two shelves that we installed last week, I managed to rearrange my cupboards finding products which I had forgotten about over time.
Since I have those two new shelves, I again have the feeling that our kitchen is endlessly big. This will not last for a long time!

Preparing rustic food and finding authentic tastes in the middle of a huge metropolis is actually fun. Being surrounded by trendy and sophisticated Parisian restaurants, great grocery stores, where one can find everything I have a bit of a countryside spirit in the kitchen.
Thanks to my friends: Rafal from Polish culinary forum Galeria Potraw, and Karolina, who started her culinary blog not so long ago, I decided to prepare my first sour rolled oats starter for another version of “żurek”, presented a few days agoMore details about rolled oats on Wikipedia.

The starter indeed is worthy recommending. Its taste is delicate in comparison to the rye starter, and it keeps its sourness. The starter was ready in 4 days, as the temperature in the kitchen was not very high (we do not have any heater in our kitchen). I was mixing it delicately every day and checking its smell. Everything went fine and so on the third day I added 2 chopped garlic cloves, and on the next day I could enjoy its nice smell. 
The good thing about the starter is that you can buy organic rolled oat in any good organic food store, either in Krakow, Paris or New York, and still enjoy your żurek without worrying about finding any rye flour for it.
Straight away I thought it could be nice to use a light vegetable broth. As I did not have any vegetable at home, and because I could not go out since our child was sick, I decided to use whey instead.


Rolled oats starter

(Makes between 800 ml - 1 liter)

Ingredients
8 tablespoons organic rolled oats, coarse-mashed in a mortar
1 liter warm (about 30°) mineral water, previously boiled
2 bay leaves
2 grains all spice
2 cloves garlic, finely chopped
1 jar (1 liter capacity), preferably sterilized
1 piece of fabric to cover the jar and 1 rubber band to hold it

Preparation
Place flour into a jar and pour the mineral water over it.
Add allspice and bay leaves.
Slowly, mix with a wooden spatula.
Cover the jar with the fabric, attach it with the rubber band and place the jar in a warm place.
Keep between 3-5 days, until the starter is ready.
The ideal temperature is between 18 and 22 degrees centigrade.
Mix delicately the liquid twice a day with a clean wooden spatula and then cover again.
If necessary, remove the foam that is forming on the surface of the liquid.
On the third day, add garlic and mix well.
Before pouring the liquid into the soup (see below) strain it and throw away the remaining oats.

Last week I also continued experiments with homemade curd for my daughter. That’s why I had around 1 liter of spare fresh acid whey, which was a leftover after cheese curding.


In Poland, I only saw fresh, non pasteurized acid whey very rarely in some good stores carrying organic food. So far, I have not seen it in France and probably the only way you can get it is curding the cheese from sour milk yourself.
I decided to use it for the soup instead of broth. In the past, I already had replaced broth with acid whey in other types of soups and it worked well. 
I do not know much detail about acid whey plasma except for the fact that our grandmothers’ opinion was that homemade whey is supposed to be very healthy, thanks to its minerals and its vitamins. I was a bit afraid whether the French stomach of my husband, who is not used to fermented milk products, would react fine to the double acidity of the soup. All in all, he liked it a lot, especially because I had added a lot of fresh thyme, which he adores. No syndromes of bad digestion were found.


I have not found any recipe for żurek using whey instead of broth. Indeed, it was my own idea to do so; however I am quite sure that it had to be used in older preparations, in those times when nothing ever could be wasted. In any case feel free to use your favorite broth. I am sure your soup will come out excellent.
Since I did not have any marjoram, which is a traditional herb used for the seasoning of żurek, I decided to go for little branches of fresh thyme, which my husband bought on the marché that day.
The soup was thicker than usual.
This mixture worked well with shiitake mushrooms, which I found in my fridge. Unfortunately shiitake mushrooms do not have so much taste and when I try this version of the soup next time, I will definitely use a few sautéed fresh ceps.

Sour rolled oat soup (żur owsiany)

Ingredients
800 ml sour rolled oat starter (finely strained from oat leftovers)
800 ml sour whey, preferably homemade (optional, you can use any broth according to your liking)
4 fresh shiitake mushrooms (around 150 g), washed, dried and cut into ½ cm strips
3 medium size potatoes, peeled, washed and cut along into thin slices of 2 or 3 mm
2 garlic cloves, peeled, washed and finely chopped
5 to 6 branches fresh thyme
1 or 2 pinches powdered chili
1 tablespoon butter
Salt

In a pan, bring the acid whey to a boil.
Add potatoes and thyme and cook on a medium flame, under cover for around 10 minutes, until potatoes are nearly soft.
In the meantime, in a hot frying pan, melt butter, add garlic and shiitake.
Fry over a medium flame between 5 to10 minutes. If necessary, add some whey if they start to stick to the bottom of the pan.
Add shitakes with garlic and their juice into the bullion.

Stunning pictures, Magda! I'm glad you like oats zurek, but thanks to Rafal (363636r of Galeria Potraw) for this recipe, not me. :)

Fermentation never stops, eh?

I also found our hot press to be the ideal fermentation chamber at home. Sometimes, I would have to remove towels and bedlinen from there just to make room for a big pot of souring milk (quark cheese), a bowl of yeast dough or sourdough doubling its volume, a jar of whipping cream infested with buttermilk to make me some beautifully silky creme fraiche, or an odd bottle of homemade kvass. Sounds mad, doesn't it?

Nevertheless, I would recommend that anyone tried, at least once in their lifetime, to make their own food product. And I don't mean making a fancy meal, but things simple and readily available at supermarkets, to such an extent that we actually forgot how to make them and how easy they are to make. Like your own cottage cheese, or sour soup, or jam, or mayonaise. This can be very rewarding and educating at the same time.

Gotta try those soured oats in a soup, though. We only eat this cereal in form of porridge, like all freshly converted Celts should. ;-)

lo said...

Żurku owsianego jeszcze nie robiłam. Z przyjemnością i ciekawością spróbuję. Fajnie tu u Ciebie. Pozdrawiam serdecznie.

wygląda smakowicie! :)

Bea said...

Je vois que tu invites à commenter aussi en français :) ce qui ne me déplaît pas ;)
Je ne connais pas du tout le goût de ce 'zurek' d'avoine, ça m'intrigue beaucoup...

Karolina: thanks a lot. I have already adjusted the text of the post. I did not remember that it was Rafal who gave the recipe for the starter.

Kucharz: Preparation of my own food products has been, for a few months, my little passion. Since I live in France, I have tried new tastes and local food and I often miss traditional Polish dishes. Unfortunately, products I can get in stores selling Polish food are of a lower quality, in comparison to those I can get in Krakow. Try the rolled oats starter when you are back from Thailand (by the way – have a safe trip and a good time there !)
p.s. Fermentation never stops!

Lo: dzieki. Namawiam do wyprobowania zurku, gdyz platki owsiane sa dostepne wszedzie, w przeciwienistwie do prawdziwej “maki” zurkowej, tj grubo zmielonego zyta. Dziekuje za odwiedziny na blogu, pozdrawiam.

Paula: dziekuje ! I rownie dobrze smakowal.

Bea: oui, tu peux toujours laisser tes commentaires en francais et je veux y repondre moi-meme, mais c’est mon mari qui doit verifier les fautes que je fais….essaye de faire ce « zurek » d’avoine, c’est tres gouteux…

Polko, dzieki. Tak sie obracam I obracam w tych zurkowych klimatach, ale obiecuje, ze to juz ostatni raz (na jakis czas!). Pozdrawiam i trzymaj sie (przed wyjazdem, rzecz jasna, przygladam sie odliczaniu na Twoim blogu – juz niewiele czasu zostalo).
