Pre-heat your oven to 325°F/163°C and cover a baking tray with parchment paper
Stir 200 grams of sourdough starter and 1 ½ tablespoons of olive oil in a medium bowl
Season with salt (See notes)
Pour on parchment paper and use a spatula to spread the sourdough as thin as you can. It will have some resistance so it maybe require several swipes. Spread it as thin as possible
Top with another crack of salt across the top
Bake in oven for 50 minutes. At the halfway point, flip the whole cracker over so each side is baked evenly.
Check that the cracker has a hard, crispy texture and remove from oven. Let cool for 15 minutes. After cooled, use your hand to break the sourdough into uneven pieces. Store in a mason jar to keep fresh.
Notes
You're free to try any add-ins to customize this recipe. Here are a few suggestions in lieu of just the salt.Sourdough Cheeze-Its
Add in 7 grams nutritional yeast and 7 grams sriracha sauce
No need to top with salt as the sriracha sauce should be salty enough
