- Total Time: 1 hour 5 minutes
- Yield: 48 crackers 1x
- Category: Snack
- Method: Dehydrated
- Cuisine: Gluten Free
Ingredients
Pre-soak:
- 1 1/4 cup flax seeds
- 2 tbsp chia seeds
- 1/2 cup ground flax
- 1/2 cup sunflower seeds
- 3.5 cups of water
- 2 tbsp culture (optional, see notes)
Remaining Ingredients
- 1 tbsp soy sauce
- 1 tsp salt
- Other flavours (see above for five different options)
Instructions
- Mix the seeds, water and culture together, and allow to soak for at least 1 hour. The flax and chia will turn into a gooey mass that forms the base for the crackers.
- Stir in the remaining ingredients along with any additional flavours. See section above for some popular flavour combinations.
- Line two cookie sheets with parchment paper (wax paper won’t work) and spread the mass of seeds as thinly as possible across the two cookie sheets.
- Bake at 250 for around 1 hour, then leave the crackers to set in the warmed oven until firm It could require more baking depending on your oven. See the notes below for making probiotic raw crackers.
- Break the crackers up and store in an air-tight container. They will last for several months in a dry cupboard.
Notes
- Flax seed crackers can be made without fermentation. However, soaking with the culture adds acid that will helps break down the seeds. Any fermented liquid will work: yogurt, milk kefir whey, kombucha, sauerkraut juice.
- To make a raw and probiotic cracker spread the seeds thinly across several parchment-lined dehydrator trays. Dehydrate at 46 C / 115F until fully dry. It may take 12-24 hours depending on your dehydrator.
- For a softer, flakier cracker, replace the sunflower seeds with 1/2 cup of ground almond meal.
- Score the crackers about halfway through baking to make square crackers.
