Preheat the oven to 300°F (150°C) convection. Line a half sheet pan with parchment paper or a silicone baking mat.
In a mixing bowl, melt 28 g unsalted butter in the microwave. (You can do it in a saucepan on the stovetop if you prefer.) Add 20 g molasses, 30 g brown sugar, 1/2 tsp dried ginger, 1 1/4 tsp pumpkin pie spice, and a Pinch of fine sea salt. Whisk together.
Finally, add 200 g sourdough discard and whisk together until smooth.
Pour the mixture onto the prepared baking sheet. Use a spatula to spread it thin and even. Sprinkle Turbinado sugar (or cinnamon sugar) across the top of the mixture.
Bake for 10 minutes, until it's set enough to score. Remove from the oven and use a pizza cutter or pastry wheel to score your desired shapes.
Return the sheet tray to the oven and bake for an additional 20-25 minutes, or until the edges are crisping up and turning brown. Remove the edge pieces to a cooling rack.Note: If you are a superhuman and manage to have a perfectly level batter, you won't have to do this. Alas, most of us regular folk have thinner edges and thicker middles, so this is how to prevent the edges from burning!
Return the rest of the crisps to the oven for an additional 5-8 minutes, or until the remaining crisps are... well... crispy! Cool on a wire rack for 10 minutes. Enjoy, and try not to eat them all in 5 minutes!
Notes
You can use active sourdough starter in place of sourdough discard if you prefer.
Store in an airtight container (a tin or glass mason jar works best) to keep them crisp. They will last in your pantry for weeks.
Feel free to scale this recipe up or down, but don't put more than 200g of discard on a half sheet tray, or your crackers will be too thick.
