Baking Glossary

Whether you’re reading one of my books, or a feature, following a recipe, or you have stumbled across this page on a google search, you may encounter some unfamiliar terms, especially if you’re new to baking. I often write about health and lifestyle medicine alongside my recipes and articles. I believe that knowledge is empowerment, and I never want to oversimplify or water down the information I share.

Too often, we assume people don't want deeper insights, but I believe that understanding the ‘why’ and ‘how’ behind baking leads to better, more intentional choices. The purpose of this glossary is to ensure that everyone—regardless of their background or level of baking experience—has equal access to the knowledge they need to bake bread that is not only delicious but deeply nourishing.

It’s not just about making bread; it’s about making sure that the people you bake for are nourished, ensuring that the bread you bake possibly impacts you, and is full of nutrients and made with purpose and care. So this glossary has been created so I can share that knowledge as generously and widely as possible in the hope that you will, in turn do the same.

Please get in touch if you have any suggestions for additions.

Kind regards

Dr Vanessa Kimbell

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.
