This is my go-to sourdough recipe. It uses a mix of rye, wholemeal, and malted flakes, along with a couple of spoonfuls of ZOE’s Daily30+ for extra plant diversity and fiber.

There’s no heavy kneading involved — just fold the dough gently to build structure and let the microbes work overnight.

The result is a deeply satisfying loaf that’s good for your gut health and digestion*, and tastes even better the next day.

Ingredients

  • 100 g wholemeal flour

  • 500 g rye flour

  • 50 g malted flakes or any flaked grain for texture

  • 300 ml water — start with less, add more as needed

  • 10 g salt

  • 100 g active sourdough starter

  • 2-3 scoops ZOE Daily30+

Method

  1. In a large bowl, combine the flours, malted flakes, and Daily30+.

  2. Add your sourdough starter.

  3. Pour in the water gradually and mix until you have a tough but hydrated dough.

  4. Add the salt.

  5. Gently fold the dough a few times to incorporate air — no kneading needed.

  6. Cover the bowl with a damp tea towel and leave it in a warm place overnight (about 12 hours).

  7. The dough should be bubbly and risen in the morning.

  8. Transfer to a floured proving basket or tin. Let it rest while the oven heats.

  9. Bake in a hot oven (ideally with a lid or Dutch oven) at 230°C for 20-30 minutes with the lid on, and 20-30 minutes with the lid off.

  10. Cool before slicing and enjoy.

*Daily30+ is a natural source of calcium. Calcium contributes to the normal function of digestive enzymes.
