Did you know that you can ferment a sourdough starter using a low-carb flour? I have been feeding my starter for 3 months now and it's going strong. I use the discard from the feedings to make this delicious cracker recipe. I've yet to make a keto sourdough bread that I'm 100% happy with, but I'll get there. In the meantime, this new cracker recipe is my favourite keto cracker I've made so far, crispy and tasty for all your snacking needs, along with the healthy gut bugs that come from the fermentation.
Keto Lupin Flour Sourdough Discard Crackers Recipe
- 320g (about 1⅓ cup) mature sourdough starter discard
- 40g (around ½ cup) golden flaxmeal
- 2 tablespoons chia seeds
- 1 tablespoon oat fibre
- 5 tablespoons olive oil
- 4-6g (3/4-1 teaspoon) fine sea salt (*Use 1 teaspoon of not using flaky sea salt garnish.)
- 1 tablespoon dried rosemary, herbs de Provence, zatar seasoning, or other spice blend) (*optional)
- 1 tablespoon nutritional yeast
- Flaky sea salt (like Maldon or Fleur de sel, for topping (*optional)
In a bowl, combine sourdough starter with flours, olive oil, herbs and salt. Mix to combine, working it until the dough comes together in a smooth mass.
Wrap tightly in plastic wrap and refrigerate for at least 30 minutes or up to 24 hours. Position oven racks in the upper ⅓ and lower ⅓ of oven; preheat to 350F. Line a baking sheets with parchment or silicone baking mats.
Roll out each piece into two oblong rectangle as thin as you possibly can. Lay out two oblongs of dough side by side (not overlapping) on each baking sheet.
Spritz or brush lightly with water; sprinkle with flaky salt if using.
Bake for 25-35 minutes or until browned and crispy, rotating the pans top to bottom and back to front halfway through baking.
Allow to cool, then transfer crackers to a cooling rack. Crackers will keep in an airtight container at room temperature for around to 10 days.
