I usually added the pulp from homemade Almond milk into my smoothies, or in my granola. My sister used it to make some awesome homemade crackers. It's a great way to reuse something that many usually just throw into their compost.
1 teaspoon of sea salt
Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper.
Mix the almond flour and sea salt in a large bowl. Add the egg and mix well, until a dough forms. (You can also mix in a food processor.)
Place the dough between two large pieces of parchment paper. Use a rolling pin to roll out to rectangle, about 1/16" thick. (It will tend to roll into an oval shape, so just rip off pieces of dough and re-attach to form a more rectangular shape.)
Cut the cracker dough into rectangles. Prick with a fork or toothpick if desired. Place on the lined baking sheet. Bake for 8-12 minutes, until golden.
