Ingredients

Dehydrated sourdough starter
Clean glass jar
Wood or silicone stir stick
Filtered water
Bread flour
Kitchen gram scale

Directions

Day 1: In a glass jar, mix 15g (2 tbsp) dehydrated sourdough starter with 30g (¾ cup) filtered water. Cover the top loosely so it can breathe. Wait 24 hours.
Day 2 — second feeding: Feed the starter with 30 g (¼ cup) filtered water and 30 g (¼ cup) bread flour, then stir.
Ready check: Wait 12–24 hours. If it has doubled in size, your starter is ready to use. If not, repeat day two.

Tip: Your starter should be bubbly and ready to make with. Keep the jar somewhere warm and out of direct sun while it wakes up.

Roasted Farmstand Salsa

Tomatoes, Anaheim, jalapeño, onion and garlic go under the broiler until they blister, then into the blender with lime. Grilled corn stirred in at the end keeps it sweet and a little chunky.
