Flax Seed: If you’re wanting to use a combination of seeds in this keto recipe, I’m sure you could. Perhaps half hemp seeds? Sunflower seeds?
Celery: I imagine that zucchini would work, too.
Avocado Oil: any oil would work here, whatever you’d like to use.
Dehydrator: If you would like to keep this keto recipe raw, you could dehydrate the keto crackers. The reason I didn’t do this for this keto recipe is because not everyone has a dehydrator and I want to make Healthful Pursuit recipes as accessible to people as possible.
I've had this dehydrator since 2007 and love it.
Food Processor: If you do not have a food processor, you could try using your blender! The key is making the celery paste. If using a blender, make the celery mixture, transfer to a bowl, then add the flax seed and mix with your hands or a large spoon.
I've had this food processor since 2010 and use it all the time!
