Ingredients
300g Canadian strong white (112)
100g Wholewheat (703)
100g Light rye (601)
300g sourdough starter
300g water
15g salt
Method
I use Kitchenaid mixer to make it easy
Place all ingredients in mixing bowl and bring together, speed 1 for 2 mins
Mix on speed 3 for 8 mins, cover bowl to rise for 2 hours
Shape into 2 loaves or 1 large. I've used Bread Proving Basket - Large Round and Bread Proving Basket - Large Oval
Cover and leave to prove 5hrs or so (when you're ready)
Heat oven with stone or baking tray to 240°
Turn loaves out onto stone, score if desired, tip water in bottom of oven to create steam, bake for 15 mins then reduce temp to 220° for a further 20mins
