San Francisco Sourdough

23 June 2016 by Vanessa Kimbell

Time at Tartine

One of the most frequent questions I am asked, is what the difference is between San Francisco-style sourdough and French-style pain de Levain. I have a pretty good understanding of French pain de levain, it is practically in my blood, but really to get under the skin of how Californian sourdough is different and finding out what the differences are, meant actually spending time in the bakeries and chatting to bakers about their processes, the flour, and the timings, and eating lots of sourdoughs.

So when the opportunity came up to interview Chad Robertson and spend time in San Francisco at Tartine on 18th in The Mission and meet other bakers in San Francisco, I was delighted.  My recordings and photos have been contributed to the team at the BBC Radio 4 Food Programme, … and for that, you will have to be patient…. scheduling good things come to those who wait.

 I have been asked so many questions since I got home from my trip, and rather than reply individually, I thought I would answer all the questions here:

Whilst you were there, did you spend time with Chad Robertson?

collage of sourdough and bakers

No, not much. It was somewhat strange.  I flew over after serval months of emails specifically to meet Chad and to do the recordings and of course to learn more about his approach to bread. I have to admit, that after the correspondence and confirmations I was somewhat taken aback that upon arrival in the bakery, slightly jetlagged but excited he was not there.  After an hour or so his PA sent an email to say that Chad was actually in Italy. In so many ways, this turned out to be a good thing that could have happened because I met and got to work with Richard Hart and the sourdough team in the bakery.

Was Tartine bread the best you’ve ever had?

Truthfully, yes.  It was the best ever. The loaf that was outstanding was actually the porridge loaves, which Richard developed the method for after ” standing in line in a bakery in California chatting about porridge with a genuine 1960’s hippie.” Richard very kindly shared the technique with me, I think that the porridge bread is possibly the best Sourdough in the world.

Will you be sharing or teaching the Tartine Method?

No. I have my own ways of approaching diversity and lifestyle medicine into a retarded bread. I think each baker has their own method. I teach Nutrition & Digestibility and everything you need to know about baking Tartine bread is already actually in Chad’s books.

How does the traditional French method differ from the Californian method?

There are some significant differences. Primarily it is down to hydration and length of fermentation, temperature, and shaping techniques, although there are differences in the flour too. The French sourdough is lighter in flavour in general. San Francisco celebrates the sour, but there are exceptions. The Tartine loaf is French-style fresh, with higher hydration and a deeper, more complex flavour, moister crumb and bien cuit crust.

Richard’s bread. Who is actually British, from East London. As you might well imagine, he has a great work ethic equalled by a wicked sense of humour and an unrivalled knowledge of naturally leavened bread. 

What do you most enjoy about the bakeries?

I loved meeting the bakers. In particular, I absolutely loved meeting Kathleen at Della Fattoria. Richard took the time to take me on a tour and introduce me to the bakeries in the area, and she adores Richard. They have a lovely rapport and she is a warm, strong, generous woman, I wanted to stay longer and learn from her. Meeting Steve from Acme Bakery was wonderful.  I found Belinda at Patisserie B warm and funny and possibly baking better French patisserie than the French! Also spending an afternoon with Michel Suas from The San Francisco Baking Institute was also a huge privilege.

What was the highlight?

I don’t think there could be a baker in the world who would disagree that hanging out with the Tartine bread baking team is about as cool as baking gets. It was just as amazing as I had hoped for. After a few days, I found myself inadvertently calling the bakery Tar – team. It is a tight space to work in, but there is a real buzz and an equal balance of male and female bakers, which was fantastic. (It was so male-orientated when I was training.) I especially love Chrystal and her sense of mischief, and Aris as well as the front-of-house staff who looked after me with strong coffee and pastries when I was feeling a bit tired and jet-lagged.

The bread team are seriously good at what they do, but they also laugh and mercilessly take the mickey out of each other in that affectionate way that people do when they are more like family than family. It was a reminder of how good it is actually to work in a bakery; the banter, camaraderie and laughter was infectious. Truthfully, I felt quite tearful leaving, I really miss that kind of atmosphere and energy, and perhaps it was simply the 3-year anniversary of Mott Greens’ death, but I felt a strong sense of connection instantaneously that I cannot explain.  It was very beautiful and reminded me of that same joy and abandon that I used to feel when I worked in the bakery in Nadaillac as a girl. 

Richard Hart at Tartine
Richard Hart has been Running the Sourdough Bakery At Tartine for 7 years.

At the centre of the team is Richard Hart, Tartine’s head baker, and Chad’s right-hand man. Richard is actually British, from East London. As you might well imagine, he has a great work ethic, equalled by a wicked sense of humour and an unrivalled knowledge of naturally leavened bread. As a hands-on manager, he bakes from the heart and can be found working with the dough as part of the production team. Having the chance to stand back and observe, it is clear that Richard also never stops thinking. His knowledge is accentuated by a creative streak, and you can practically hear his mind ticking as he develops ideas and flavours with an instinct I have rarely seen before;  it didn’t come as a surprise to realise that it was Richard who developed the bread recipes in Tartine’s third book. So, to answer the question … the absolute highlight of my trip was doing some recording with Richard. Being around such an amazing baker was inspiring: for me, there is no greater gift than inspiration.

Did you get to meet Chad Robertson in the end?

Yes. in the end Chad popped into the bakery for a couple of days. It seemed that absolutely everyone loves to stop and chat with Chad. So yes,  I got to chat, during which time I met half of the neighbourhood; almost everyone who walks past stops to pass the time of day. It’s actually a warm community, and Chad seems very much part of it. We met three times over my stay and eventually, I recorded some interesting audio, but as you might imagine, he was incredibly busy and in Rome for the first part of my visit. He is in the middle of an exciting new project building large versions of the bakery for up-scale production.  I hope he retains the love and friendship as he grows the business, this is the real secret to this bread. 

Did you get your books signed by Chad?

Of course!

Do I have some Tartine starter?

Yes… I gave incorporated it into my starter  – will I be selling it? … er no…but I am happy to gift a starter to anyone who wants to bring a pot to me for personal use only.

Did you visit any other bakeries?

I managed to visit about a dozen other bakeries, tried the sourdough, and met the bakers from Acme Bakery, the San Francisco Baking Institute, Patisserie B, Della Fattoria, Craftsman and Wolves, Arizmendi Bakery, Boudin Bakery, Nightingale Bakery, The Neighbour Bakehouse, and several others, all making fabulous sourdough.

What did you think of Boudin Bakery?

It was not to my taste. That is all I’m saying.

Did you learn anything new about sourdough?

Yes, lots, there is always something to learn, especially about the future of sourdough and the direction of artisan bread. I think one of the key things was learning about the flour and observing the production methods first-hand. I learnt a lot about the history of sourdough from bread historian and author William Rubel. William and I have been chatting on his bread history group for a couple of years, and he has a unique insight into the history of bread. He is utterly gorgeous, and I can’t thank him enough for coming to meet me… William is currently writing a full history for the University of California.

What idea’s will you use from your trip?

The most important information was the full picture of San Francisco Sourdough, but the ideas that most inspired me were actually from Tartine Bar.  The food was absolutely incredible, and I found myself pouring over a recipe book that had sat and languished on my bookshelf for a long time. The whole approach set me on fire, so ironically it wasn’t so much the sourdough but the extension of the fermentation that I will integrate into what I do here.

Will you go back?

After tasting such amazing bread I am not sure I could resist returning.

    Great post! Your insight into the industry from the behind the scenes and historic perspective.. fantastic! Most people can appreciate the bread .. the product of a lot of hard work: research, trial and error and labor of love. Baking bread is a more than the commercialized, industrialized method of the past 40 years.. its revival back to the roots benefits everyone. Nutritionally speaking, Taste! Flavor and Craft.
    Each bakery/ baker adds a new nuance via their interpretation of bread. It maybe just flour, water, leaven, salt… but the combinations permutations are almost infinite in the complexity of interpretation and execution. Because if all SF sourdough was boudin… oh boy what fun is that? 😉
    Keep it up. You, Chad and the dedicated artisans of the ART of Baking… Thank you.

    I recently visited Tartine, but the crowds, parking and timing (bread wasn’t ready for sale yet) denied me a opportunity to purchase a loaf. I guess there is always next time..

IBS AWARENESS MONTH Do you suffer from irritable IBS AWARENESS MONTH

Do you suffer from irritable bowel syndrome (IBS)? It can be tough to deal with the uncomfortable symptoms of stomach cramps, constipation, diarrhoea and bloating. But did you know that making dietary changes, such as incorporating sourdough bread into your diet, could help alleviate some of those symptoms?

Studies have shown that sourdough's long, slow fermentation process can reduce IBS symptoms. Plus, during #ibsawarenessmonth, we're exploring how adding different herbs and spices to your sourdough can further improve both the flavour and the digestion of your bread.

Let's talk about gut health, fermentation, and how sourdough can be a delicious and healthy addition to your diet. Join the conversation and share your experiences with IBS and sourdough.

THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME

One of the biggest issues around using a plastic lame to score sourdough, of course, is that eventually the blade will become blunt and the lame could end up in landfill.  So several years ago I talked to my dear friend EJ about developing a lame with a replaceable blade. And he came up with this very beautiful hand carved wooden lame.

Very sadly EJ is no longer with us. Recently a friend of EJ’s who is also a wood turner and carver offered to make these again for us in remembrance of our dear friend.

The Baking As Lifestyle Medicine (BALM) Protocol The Baking As Lifestyle Medicine (BALM) Protocol

The current food system is broken at multiple levels, from the pesticides used in our soils to the emulsifiers and additives adulterating industrially-processed foods. Nowhere is this more apparent than in the bread we eat.  The figures reported by the UK Flour Millers say that bread is bought by a staggering “99.8% of British households” and that “the equivalent of nearly 11 million loaves are sold each day. Approximately 60-70% of the bread we eat is white and sandwiches are thought to account for 50% of overall bread consumption. Average bread purchases are the equivalent of 60.3 loaves per person per year.” 

Most bread sold is made by modern processing methods that strip heart-healthy whole grains of their nutrient contents, resulting in low-fibre bread with a high glycemic index. Over time, white processed bread can increase a person’s risk of insulin resistance alongside other lifestyle diseases.

We’re on a mission to revolutionise the bread making process at every level – from soil to slice. The rules governing this are laid out in our Baking As Lifestyle Medicine protocol.
