Gathering Your Ingredients
Let’s explore what makes these crackers special:
Cracker Base
- 1 cup active sourdough discard (100% hydration) – The star! Use discard straight from the fridge
- 1/2 cup whole wheat flour – Adds nutty flavor and extra crunch
- 2 tbsp ground flaxseed – Binds dough without eggs (vegan!)
- 1 tsp sea salt – Balances the tanginess (divided)
Herb Infusion
- 2 tbsp fresh rosemary – Finely chopped for earthy notes
- 1 tbsp fresh thyme leaves – Delicate lemon undertones
- 1 tsp garlic powder – Adds depth without overpowering
- 1/2 tsp cracked black pepper – Optional spicy kick
Step-by-Step Cracker Crafting
Mixing the Dough
- In medium bowl, combine discard, flour, flaxseed, and 3/4 tsp salt
- Add herbs and seasonings, mixing until shaggy dough forms
- Pro Tip: Don’t overmix! Stop when no dry streaks remain
- Cover with damp towel; rest 15 minutes while oven preheats
Rolling & Scoring
- Preheat oven to 350°F (175°C) with rack in center position
- Divide dough into two portions for easier handling
- Place first portion between parchment sheets
- Roll to 1/16″ thickness – thinner means crispier!
- Remove top parchment; lightly brush with water
- Sprinkle remaining salt over surface
- Score into rectangles with pizza cutter or knife
Baking to Perfection
- Transfer parchment to baking sheet
- Bake 15-18 minutes until edges turn golden
- Rotate pan halfway through for even baking
- Check after 12 minutes – thickness determines bake time
- Cool completely on wire rack before breaking into pieces
Flavor Variations to Try
Herb Options
- Italian Garden: Basil + oregano + sun-dried tomato bits
- Everything Spice: Sesame seeds + poppy seeds + onion flakes
- Southwest Kick: Smoked paprika + cumin + chili flakes
Dietary Adaptations
- Gluten-Free: Use 1:1 GF flour mix (results slightly denser)
- Nutty Version: Replace 2 tbsp flour with almond meal
- Cheesy Vegan: Add 2 tbsp nutritional yeast to dry ingredients
Keeping Crackers Crisp
- At room temperature: Store in airtight container <= 1 week
- Reviving soft crackers: Bake 5 mins at 300°F to re-crisp
- Freezing: Keep unbaked dough disks up to 3 months
- Serving Suggestion: Pair with hummus, mashed avocado, or olive tapenade
Common Cracker Mistakes Solved
- Crackers puffing? Dock dough with fork before baking
- Browning unevenly? Rotate pans + use convection setting if available
- Dough too sticky? Rest covered 10 mins before rolling
- Too thick/chewy? Roll thinner – should nearly see through parchment
Cracker Questions Answered
Can I use starter that’s never been fed?
Absolutely! The acid content actually enhances flavor. For less tang, use recently-fed discard.
What if I don’t have fresh herbs?
Substitute dried herbs – use 1/3 the amount since they’re more potent.
Why add flaxseed?
Flax binds dough while adding fiber/nutrients. Chia seeds work too!
Can I make these gluten-free?
Yes – use GF flour blend. Expect slightly denser texture, and roll thinner.
How do I freeze the dough?
Portion into disks, wrap in plastic, then freeze in airtight bag. Thaw overnight before rolling.
Best flour substitutes?
Spelt, rye, or einkorn flour all work beautifully for distinct flavors!
The Art of Discard Transformation
These golden crisps turn what many consider kitchen waste into something truly extraordinary. With their satisfying snap and herb-forward flavor, you’ll find excuses to make sourdough discard just to bake another batch. Share them at picnics wrapped in parchment, stash some in lunch boxes, or serve alongside soup instead of croutons – however you enjoy them, each bite celebrates the magic of fermentation and mindful cooking. Once your kitchen fills with the rosemary-scented aroma of baking crackers, you’ll wonder why you ever threw away starter discard at all.
