Professional Bakers: Certification In Baking As Lifestyle Medicine

Big Poops Bread

22 June 2021 by Dr Vanessa Kimbell
Diversity Score: 9 (if you include salt, oil and butter) or 24 of you use our Meadow Blend Flour and a whopping 31 you use the spice mix.

One of the healthiest everyday breads you can bake.

Big Poops Bread
We've made up the 30+ different ingredients for you in an easy Ingredients Kit.

This recipe is what I call big poops bread. Gut health is about regular fibre, and when you ferment your bread it predigests it. It is also about keeping it regular ( pun intended) So I have created a recipe box with exactly the amounts you need to make this recipe, already weighed out, to make either 2 or 4 of these breads with the option to bake this amazing bread with  a whopping 31 diverse ingredients! 

It's quick to make because it follows the Basic 10-Minute Sourdough Tinned Loaf schedule, but this version includes our 8 seed blend. It delivers a phenomenal amount of fibre and flavour and it is satiating, making it a great loaf for anyone who wants to control blood sugar levels. The bread seeds also bring a high level of nutritional value to this bread.

Our Big Poops Bread has a Diversity score of 31

(if you use the recommended flour, seeds and spices)

It packs a whopping 15.7g of fibre for 200g  - which is over half the daily recommended amount of fibre in your bread alone.

Fibre levels

  • Fibre per 100 g of Bread: 7.7 g
  • Fibre per 80 g Slice: 6.16 g
  • Fibre per 200 g of Bread (Recommended Daily Intake): 15.4 g

Healthy Seeds

Seeds have numerous benefits for human health. For a start, they are prebiotic and good for the gut microbiota because of their high levels of dietary fibre and polyphenols. Studies have shown that they can have a positive effect on the prevention and management of obesity, which seems to be associated with these prebiotic properties. However, I recommend exercising caution with seeds if you have IBS. This can vary from person to person, but sometimes they are not well tolerated. Soaking the seeds and draining them will help. However, if you are not used to seeds, I suggest that you start by adding just 50 grams to the recipe and work your way up with another 50 grams over 5 weeks or so to retrain your microbes. Be gentle with yourself; if you are just getting into a healthy way to bake, it can take time to retrain your gut.

Gut Health

Fibre benefits your digestive system and reduces your risk of developing chronic disease. Fibre also leaves your stomach without being digested, moving into your colon, where it feeds friendly gut bacteria. Considering this loaf takes only 10 minutes of hands-on effort to prepare, you can gain many benefits from an achievable everyday endeavour.

A practical everyday loaf

The recipe makes two loaves. I slice it thin for sandwiches and thicker for toast. If two loaves is too much bread for you, simply halve the recipe. If you do this you must be careful to maintain your DDT when mixing as a smaller amount of dough will lose heat more quickly. Better still, make two loaves and give one away. Or, if you prefer, you can bake two, enjoy one fresh, and slice and freeze the other.

Intentions

One of the biggest problems people tell me they have when making this loaf part of their everyday baking and eating is that they are so busy they forget to order the flour to bake with. I am therefore delighted to be able to offer a monthly subscription to the ingredients for this loaf.  It makes 4 loaves, enough for one a week.

What I love most, aside from the taste and the satiety of this bread, is that when you use the Meadow Blend flour, the seeds and the spice blend together, this loaf can deliver a diversity score of 31: at least 30 is recommended for optimal gut health.

Seeds: Coriander, Caraway, Fennel, Anise and Nigella Seeds

Happy baking

Dr Vanessa Kimbell

x

 

Starter: Any starter as long as it is bubbly and alive - I used my white starter for the recipe.

Makes 2 x 1kg > Hydration 95%

DDT: 27C

Flours

The brand of flours used in this formula
  • Strong White Stoneground Bread Flour
  • Wholegrain - I recommend Botanical blend No 2 but if you are new to baking and just want to try a standard flour then use a standard stoneground strong wholemeal flour. Although this does not increase your diversity score.

For The Leaven

  • 200g bubbly, lively (second-build) sourdough starter

For The Dough

  • 950g water at 27°C (82°F) (200g of this will be used to soak the seeds) + 50g optional extra water
  • 250g of my 8 seed mix
  • 1 large tablespoon of 5 my spice blend (optional)
  • 500g stoneground white bread flour (included in our kit)
  • 500g stoneground wholegrain bread flour - I recommend Botanical Blend No 2
  • 20g fine sea salt
  • a large knob of room temperature butter, or coconut oil for greasing
  • A tablespoon of honey as an optimal extra to finish

Bake Time

50 - 60 minutes - pay attention to your oven - everyone oven is different and you need to get to know your oven. Check it is cooked by inserting a skewer - if it is done then it will come out clean.

Equipment

  • 1 small mixing bowl
  • 1 large mixing bowl
  • Whisk
  • Spatula
  • 2 x 1kg (2lb) loaf tins
  • Olive oil spray
  • Oven gloves
  • A jug of tepid water in which to dip your hands when handling the dough

Tutorials

Rebuild your starter by refreshing your sourdough starter (we call this first build) Day 1, 8pm first build
Refresh starter again (second build makes your starter very vigorous) Day 2, 8am second build
Mix 180g of the seeds with 200g of the water and leave on the side until the evening Day 2, 8am
Using a spatula or strong wooden spoon, mix your leaven, flour, salt, soaked seeds and any liquid, and the remaining water and mix well; then get your hands in and mix. Remember to keep your DDT - desired dough temperature. Day 2, 7pm
Adjusting the hydration - Depending on the flour you chose and the age of the flour, you may need to add more water so add in small increments of 20g, and give a few minutes rest before adding more, then leave to rest for 1 hour.Day 2, 7.05pm
Butter your tin and scatter with the remaining 70g seeds to coatDay 2, 7.10pm
Transfer the dough to the tin and cover. Leave to prove overnight on the side in the kitchenDay 2, 8pm - Overnight
In the morning you can return your now bubbly starter to the fridge - it will be alive to use for another 2 days and then you need to rebuild it if you want to bake again . Day 3, 8am
Bake your bread Day 3, 8am

My Top Tips for Success

Proofing tips

If your kitchen is cold, find somewhere slightly warmer to do your proofing. Yeast likes an ambient temperature of 20c or above. If you yourself are cold then so will the yeasts be. You can buy a proofing box to make this task easier, but the heat from the oven light should provide enough extra heat to keep your bread a little but warmer overnight – just don’t let anyone accidentally turn the oven on while it’s in there!

Baking Tips

Your dough will be proved the following morning, and your loaf should be at least 50 per cent bigger. Preheat your oven to 220°C/gas mark 7 for 30 minutes, and place a shallow baking tray in the bottom of the oven.

As you place the bread in the oven, reduce the temperature to 180°C/gas mark 4 (this will stop your crusts from burning) and carefully throw a little water or some ice cubes into the hot tray at the bottom. Close the door quickly to trap the steam this creates. Bake for 50-60 minutes. Everyone’s oven is slightly different, so check your loaf towards the end of the baking time: it should have a golden brown crust.

Remove the loaf from the oven and leave to rest in the tin for about 5 minutes, then turn your bread out of the tin and place on a wire rack. Here at The School, I recommend you return the unmoulded loaf to the cooling oven and leave there on the wire rack to let the last heat drive off any remaining moisture in the bread. This way I get an epic crust and an amazing golden finish.

Your starter is now really active and should be ready to put in the fridge until you next want to prepare it for baking.

Storage tips

Once cool, store your loaf wrapped in a clean, dry tea towel. With a wholegrain loaf I recommend giving it a few hours to settle. I appreciate that warm bread is irresistible, but a bit of patience will pay off. I suggest, as always, that you bake two and slice one as it cools and pop one in the freeze. If freezing, please do remember to wrap the bread well to stop freezer burn.

Best enjoyed within 2-3 days.

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.
