Recipe Introduction

A nutty, tangy, lively and fibre-rich boule for healing the gut, this recipe has a long slow fermentation supporting improved digestibility, and with a variety of whole grains, it aids in reducing inflammation, improving bowel function and increasing gut microbiome (community) diversity.

It was created for my husband: He was diagnosed with Colon Cancer a few years ago, leading us on a journey of learning about and paying better attention to our overall health, but more specifically gut and colon health.

As a student at The Sourdough School, I've learned about the amazing benefits of whole grains for gut health, which lead me on a quest sourcing local flours and grains for my bakes. I spent several years as an Organic farmer in rural Canada, dating back to 2009, which connected me to the local Amish Community I worked alongside. My connection to these rural communities is what led me to local mills to source the variety of grains and flours I used for this gut healing recipe.

Created for the health of my family, this recipe is built around connection and community and as with all good things in life, is best shared.

How to Store

Store up to 5 days on counter in a clean linen bag. Best eaten within the first 2-3 days then works great as a toaster bread.
Freezes well either sliced or left whole to enjoy fresh at a later date.

Top Tips

Removing 75g of the total water and incorporating it back in through a bassinage helped the different flours in the mix absorb the water better overall and made the initial mixing easier. Also, extending the cold ferment from 16hrs to 24hrs helped create a tighter loaf for easier scoring and added richer flavour.
