farina di castagne (chestnut flour)

I  received as a gift a kilogram of chestnut flour.  Seems like fresh and lovely stuff....but I would appreciate some general advice from fellow bakers who have used chestnut flour in their breads.   Is it better used in sweet recipes,  will it be too strong a flavor in an Italian bread, can it become part of a multi-grain mixture?  

Thank you all....and Happy Holidays!

I’d been wondering lately what to do with a small amount of chestnut flour that was languishing in a bowl in the cupboard when I saw this thread started by dorothydean (Thank you Dorothy!) after she’d read about Casola Marocca on the Slow Food Foundation website.


Chestnut Flour


I brought back around a kilo of chestnut flour from a holiday in Tuscany last October. The holiday had been organised by The Handmade Bakery, the UK’s first Community Supported Bakery (CSB), and included three mornings of baking classes (which turned into more like 3 full days!). We were staying in a villa in Ponte a Moriano, near Lucca, in the foothills of the Alpi Apuane in the north west of Tuscany (Garfagnana region).


October sees the start of the chestnut harvest in the mountains (the chestnut trees only grow above a certain altitude, above the level of the olive groves & vineyards) and on the first day of our holiday we visited the mountain village of Colognora where a chestnut festival was being held. The weather was atrocious, and by the time we arrived (after getting a little lost) the torrential rain had caused the smattering of small food & craft stalls that had been erected amidst the narrow, steep & stony streets, to start packing up. A few hardy souls continued to roast chestnuts, distributing them gratis in soggy paper bags. We were treated to a tour of the Chestnut Museum by the museum’s director, who unfortunately spoke no English. With long fluid sentences & elaborate hand gestures (translated into curt one-liners by our Australian guide!), he explained the innumerable applications of the sweet chestnut; we’d run out of time before we even got to the culinary uses, but there’s a useful summary here.


In order to make flour, chestnuts are dried over smouldering chestnut wood & old husks, in specially built smokehouses, before being shelled & stone-ground.


There seems to be some dispute over it’s keeping qualities, with some sources saying it keeps well year round, whilst others say it needs to be kept in the freezer. This might be affected by production methods which I believe also vary. Mine has kept perfectly well in the cupboard since October.


In the UK, Shipton Mill produce a flour from ‘chestnuts [that] are sourced directly from a small hill farmer, Patrice Duplan, who gathers them from the hills in the Ardeche region of Southern France', according to the blurb. In Tuscany we were told that the French use a different method of drying the chestnuts (I forget how - I've got a vague memory it involved paraffin?! – although I'd be surprised if this was the case with the Shipton.


Other UK sources (thanks zeb) include http://www.luigismailorder.com/ & http://www.flourbin.com/


I have also seen it stocked in wholefood shops.


In the US, Dorothy found this online supplier: http://www.chestnutsonline.com/ & breadsong found it here.


The flour seems very expensive in relation to bread flours, but when compared with other nuts, ground or otherwise, it is very reasonable.


Recipe


The recipe that mrfrost dug up was a hybrid whilst Daisy_A found a pure sourdough version.


(Thank you both!)


Both recipes were in Italian but had been google translated. I started the mrfrost recipe before seeing Daisy_A’s post but had decided to leave out the commercial yeast anyway.


I didn't have as much chestnut flour as the mrfrost recipe called for, so made up the amount with extra white bread flour. After all the additions, the dough was still dry & crumbly, so I added the potato I had left over & extra milk to make a stiff, sticky but workable dough.


So my modified recipe was as follows:


290g  chestnut flour


210g  strong white flour (Doves Farm)


10g    salt


150gr  sourdough


100g   milk


80g   water


20g   oil


110g   mashed potato


Method


I only kneaded it briefly after mixing as I figured there wasn’t much gluten to develop. I gave it a ‘fold’ after the first hour - a bit of an exaggeration: the dough had lost a little of its stickiness but was still stiff, so all I did really was to form a slightly smoother, taughter ball than before.



After another hour, the dough had some spring & had lost it’s stickiness. I just tightened up the ball, being careful not to tear the surface, and put it into a floured banneton. I’m not sure what my reasoning was for doing this, it was more an instinctive act! I guess I felt that the dough wouldn’t benefit structurally from any more folds. If I do this again, I might knead just a little longer after mixing until the stickiness is gone & then put it straight in a banneton.



Another 2.5 hours later, the dough had risen only slightly, almost imperceptibly. I was faced with a choice (since I had to go out an hour later): I could either bake it, leave it on the counter for another 4 or so hours, or refrigerate it (if I could find the space, which was doubtful). I decided to bake. I turned out the loaf and scored it with a deep cross, as mentioned in Daisy_A’s post.




I baked in the same way as I usually bake my sourdough wheat breads: on a preheated kiln shelf, starting high (250-60c) with steam (boiling water in tray below) for 15mins, then down to 200c. I checked internal temp after 30 mins (c.60c) & 40 mins (c.75c). After 55 mins, the internal temp was 92c but the bread still felt very heavy & moist. I needed to leave, so I turned the oven off but left the loaf in.


Results


The dough was obviously underproofed & the bake a bit high, but the result was very visually appealing. I don't think the picture gets the colour very accurately: the crumb was quite purple when first sliced (think darker & more purple than walnut bread), with a purple-red-brown crust, which darkened & mellowed overnight to a chestnut brown (go figure!); the crumb colour too was less pronounced a day later.


When I sliced the loaf in half, I was worried that it wasn't quite done & would be gummy like rye can be, but not at all. Although visually, the crumb texture resembles a rye bread, it feels very different to the touch & in the mouth: it's much drier for a start; this might be due in part to the manner of baking, but I also think that the chestnut flour retains less water than rye. I imagine that one reason for adding the potato is to preserve moisture.



The high bake led to a crunchy crust, like a sweet nutty biscuit (I think the milk contributed to this), which is a great contrast to the close textured, almost meaty, crumb. The sweet smoky flavour is terrific & I’ve had some rapturous responses from some friends who tried it.


I had it first with some Manchego, & the following day with a very similar, but more authentic(!), Pecorino Toscano, both hard ewe’s milk cheeses: a wonderful combination. I also made a mushroom soup, using fresh mushrooms & dried porcini, which was also a good accompaniment.


Other suggestions are soft goat’s cheese & (chestnut) honey, and lardo di Colonnata, or any other salty Tuscan (or other) cured meat.


Why not give it a go!

Recipe for or thoughts on Italian chestnut flour and potato bread (Casola Marocca)?

February 9, 2011 - 8:37pm -- dorothydean

I'm searching for a recipe for a bread described on the "Ark of Taste" section of the Slow Food web site--an amazing-sounding bread made with chestnut flour, wheat flour, and a little bit of potato, with milk and olive oil. The bread is called Casola Marocca. I've also seen it online as Marocca di Casole.

Glezer versus Reinhart


After getting Reinhart's "Bread Baker's Apprentice" for X-mas this year (thank you sis!) I baked my first bread "from the heart" and I loved it!!! So far I've been a "follower" of the Maggie Glezer-way of going about business:


 


I've been meticulously studying formulas and weighing ingredients to the milligram, producing very nice loafs as a result. But after baking with my head so much, it is time to start baking with my heart!


 


Reading Reinhart made me take a leap of faith; or to be more exact; it awakened my faith in myself! Look at the dough, feel the dough, work it the way you feel it's right! I love this whole approach, and I guess I was ready for it, knowing about the basics of bread by now (thank you Maggie!)


 


So, when I was looking around for a good formula using the chestnut flour I brought back from Rome two weeks ago, I decided to just go ahead and DO IT! Based on the general knowledge about the chestnut flour I concocted my own little dough and produced a batch of wonderful rolls, fragrant with the smell and taste of chestnut, with a nice crust and an okay crumb (I guess this would be the moment where, if Glezer were to read this post, she would comment: If you would do it my way, your crumb would have been more than okay as well...)


 


Very tasty! If you want to see my "year in baking" slideshow, you can find that here



 


I really hope you all enjoyed a wonderful X-mas. Check my blog in the coming days if any of you TFL'ers in the good old USA are interested in some traditional Dutch New Year's eve baking. I will show you how to make  "oliebollen", the precursor to what you guys have turned into.... donuts! I will also be baking the traditional "knieperties", a New year's treat that stems from the region in the north that i grew up in, and that I love because there is a wonderful simplistic symbolism attached to them. More to follow! Have a good week!
