In these cases, it needs daily refreshing, and before richer doughs, like those with butter and eggs, we often do three consecutive refreshments. The result? We end up with quite a bit of sourdough discard! Throwing it away would be a shame, so I always try to reuse it intelligently. After all, refreshing increasing amounts each time is not a sustainable solution. When I reach about 150 g of discard, I take the opportunity to prepare something tasty, perfect to bring to work for lunch or keep in the pantry for a quick snack. Today, for example, I decided to make some simple tomato swirls, crunchy on the outside and soft inside, also ideal for enriching an aperitif or a savory snack. For cooking, I used the air fryer: 15 minutes at 356°F, and they came out perfect! If you prefer, you can also bake them in a traditional oven at 392°F until golden brown. A zero-waste recipe, super tasty, and very easy to prepare. Let's see how to make them! Beforehand, I'll remind you of other recovery ideas.
