Olive, Rosemary & Sea Salt Sourdough Focaccia Recipe by Michael James

I want to bring you the connections, tastes, flavours and friendships at The School.

I am so delighted that I can share the olive oil with you all from the olive groves around the castle where I teach in Tuscany in this new baking kit. I’ve been working with Ben at Deilverdeil to make life easier, with subscriptions and the ingredients you need for the recipe delivered in a convenient box and they make fabulous presents.

The olive groves are incredible, and the owner, Charlotte, describes them as part of a bio-diverse fortress. There has been a castle, wine, and olives here for over 3000 years, and the olive oil is one of the best I have had. Charlotte is a phenomenal woman who breathes authenticity and integrity in every breath. So this is a beautiful moment to share this Olive Rosemary and sea Salt Sourdough Focaccia recipe that uses this oil from the castle.

Olive oil and why this might help towards longevity

Olive oil is a key component in how people eat their bread in the Mediterranean. The compounds in olive oil that provide these health benefits are polyphenols, specifically oleuropein and hydroxytyrosol. These natural antioxidants help improve blood sugar control, reduce blood pressure, and decrease the oxidation of low-density lipoprotein (LDL) cholesterol. High-quality, extra virgin olive oil contains higher concentrations of these beneficial polyphenols compared to refined oils, making it a healthier choice for reducing the risk factors associated with metabolic syndrome.

Meet Baker Michael James

I’m also delighted to introduce another dear friend and long-time colleague, Michael James. Michael and I have collaborated numerous times at The Sourdough School, sharing our passion for artisan baking and the art of sourdough. In this exclusive video, he demonstrates how to make delicious sourdough focaccia using one of my favourite ingredients. With his new book just released, there’s no better time to dive into his exceptional techniques. Join us as Michael brings his expertise to your kitchen—you’re in for a treat!

This recipe is from his previous book, All Day Baking: Savoury. Michael amended it to include 30% wholegrain (or Botanical Blend flour) to increase diversity and fibre in line with our BALM Protocol. You can obtain all the key ingredients in this recipe with our convenient pre-measured recipe kit found here (just add olives and rosemary).

Olive, Rosemary & Sea Salt Overnight Sourdough Focaccia Recipe by Michael James

Olive, Rosemary & Sea Salt Sourdough Focaccia Recipe by Michael James

Makes: one slab, in a 9 x 13 inch deep sided baking tray

This crowd-pleaser is a great introduction to bread making as it is very forgiving. It is baked in a pan, so no technical shaping skills are required. Kids love to get their hands into the dough and have fun arranging the toppings. You can top the focaccia with anything you like—I also love it with onions, anchovy, tomato, or roasted garlic and a drizzle of balsamic vinegar.

The dough can be made by hand or in an electric stand mixer, although the dough will be stronger with a mixer. Instructions for both methods are included.

I prefer to use a deep-sided tray so the dough and oil are contained. I also find the edges crisp up better during the bake and it won’t dry out after baking.

The key to success here is having a healthy starter fed at least three times before you use it. I feed it the night before and use it to make the dough first thing in the morning. I recommend the following feed schedule:

Below is a video on Micheals’s top tips on how to look after your starter. I hope you enjoy the recipe

Potentino extra virgin olive oil

 

Day 1

Take 20 g (1 tablespoon) of starter, and feed it with 20 g (1 tablespoon) of water plus 15 g (1 tablespoon) of bread flour. Leave on the side until doubled in size and ripe and bubbly.

Day 2

In the morning feed your starter with 20 g (1 tablespoon) of water and 15 g (1 tablespoon) of bread flour. Leave on the side until doubled in size and ripe and bubbly.

In the evening feed it with 40 g (2 tablespoon) of water plus 30 g (2 tablespoon) of bread flour. Leave on the side until the morning when it has doubled in size and is ripe and bubbly.

This will give you enough starter for the recipe plus a little left over for continuation.

Day 3

When the starter is ripe and bubbly from its feed the previous evening. Start to make the focaccia in the morning following the method below.

Ingredients

Dough

  • 420 g strong white flour
  • 180 g wholegrain flour [or Botanical Blend]
  • 480 g water
  • 120 g starter
  • 12 g salt
  • 15 g olive oil plus extra for drizzling on top

Topping

  • 80 g green and black olives, pitted
  • pinch flaky sea salt
  • 3 to 4 sprigs rosemary, chopped

Method

To make the dough by hand, combine the flour, 410 g of water, starter and salt in a medium sized mixing bowl. Mix with your hands until you have a cohesive mass, and then scrape down the bowl and your hands. Stretch and fold the dough for around 5 minutes to build up the dough structure. Once it is getting stronger and if it is not too sticky, mix the remaining 50 g of water followed by the olive oil. This should take another 5–6 minutes. The dough will be quite wet and sticky but don’t worry; the pan will hold it together.

To make the dough in a mixer, combine the flour, 430g of water, starter and salt in the bowl. Mix with the dough hook for 5 minutes on a medium speed until it all comes together. Scrape down the sides of the bowl, and then add the remaining 50 g of water and the oil. Continue to mix on a medium speed for another 5 minutes until it is smooth and quite elastic. You should be able to stretch the dough with your hands.

Once the dough is mixed, cover it in the bowl with a damp tea towel and rest for 30 minutes at room temperature.

Give the dough a set of folds every 30 minutes for the first 2 hours. To fold, wet your hands and grab a piece of dough on the side of the bowl. Pull and stretch it up over the middle to the other side of the bowl. Repeat this 6–8 times, moving around the edge of the bowl. Cover and rest the dough between folds. It should become very strong and stretchy over time.

After the last set of folds, cover and rest the dough for 2 hours more, ideally at around 24°C–26°C. If it is too cold you can place it into your (cold) oven with a light on and with a pan of hot water at the bottom to create warmth and humidity.

If you want to bake your focaccia the next day cover it with a damp tea towel and place in the fridge. The next day let it come up to room temperature and finish proving as below.

Take a deep-sided baking tray and line it with baking paper or a generous amount of olive oil. Wet your hands and place the dough into the middle of the tray and use your fingertips to gently massage and stretch the dough into the corners, so it is fairly even in depth. Cover once again and leave it in a warm place to prove. The proving time is variable and dependent on the room temperature; if it’s cooler let it prove longer, if it’s warm you will be able to bake sooner. As a guide it should take 1½–2 hours at a temperature between 24°C–26°C. It’s ready when the dough has risen by half and is nice and bubbly and wobbly as you shake the tray. If you poke it with your wet finger it should be soft; if it springs back quickly it is under-proved so give it more time in a warm place.

Preheat your oven to 230°C/445F/Gas mark 8 about 20 minutes before you bake. Place one shelf at the top of the oven for the focaccia and one below with a small shallow tray on it. (Later you will pour a small amount of hot water into this tray to create steam, which helps the dough rise during the initial part of the bake.)

Drizzle two thirds of a tablespoon of olive oil over the top of the focaccia. Oil your fingertips and gently push them into the dough until you can feel the bottom of the pan, leaving space between each press. Scatter with the chopped rosemary and sea salt, and press the olives gently into the dough so that they are still exposed on top.

Place the focaccia onto the top shelf and pour 100ml of boiling water into the tray on the bottom. Bake for 25–28 minutes until golden on top. Turn the tray and remove the steam tray halfway through the bake.

Once baked, leave to cool in the pan for a couple of minutes before transferring to a wire cooling rack.

This olive sourdough focaccia is wonderful to eat still hot from the oven, and will keep well for a few days if you manage to resist eating it all on day one.

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.
