Weigh out and chop your pecans into rough sized chunks. Toss in a large mixing bowl. Add your oats, flaxseed, cinnamon, cardamom, brown sugar, and salt to the mixing bowl. Mix until everything is well mixed. Set aside.
4 (400g) cups old-fashioned oats, ¾ (90g) cup chopped pecans, ½ (60g) cup ground flaxseed meal, 2 tsp cinnamon, ¼ tsp cardamom, ½ (100g) cup brown sugar, ½ tsp sea salt
Melt your butter in a microwave safe dish or in a small saucepan. Pour the butter into a mixing bowl.
⅓ (75g) cup salted butter
Allow the butter to cool slightly, then add your sourdough discard, maple syrup, honey, maple flavoring, vanilla extract, and Greek yogurt. Whisk together the wet ingredients until smooth.
½ (120g) cup sourdough discard, ⅓ (80g) cup honey, ⅓ (80g) cup maple syrup, 1 tsp vanilla extract, 1 tsp maple extract, ¼ (60g) cup Greek yogurt
Note on adding egg whites: If you choose to make this granola without the fermentation step, you can add the egg whites to the wet ingredients and whisk them in. If you're fermenting the granola overnight, wait to add the egg whites until right before you bake the granola as the egg whites can't sit out overnight safely.
Pour the wet ingredients over the dry ingredients and stir well to coat evenly. If you're baking same day, skip the optional fermentation listed below.
Optional Overnight Fermentation: Cover the bowl with a breathable cloth (like a tea towel) or plastic and let it sit at room temperature for 12 hours to allow fermentation. Keep it in a warm spot (75-80°F) for the best results.
