Ingredients

• 100 g sourdough starter (active)
• 350 g spelt flour
• 220 ml warm water
• 2 tbsp olive oil
• 1 tsp salt
• 2 large, thinly sliced yellow onions
• 100 g, crumbled goat cheese
• 1 tsp, chopped fresh rosemary
• 1 tbsp balsamic vinegar
• 1/4 tsp black pepper

Instructions

1. Step 1: In a large mixing bowl, combine 100 g active sourdough starter with 220 ml warm water and 2 tbsp olive oil. Add 350 g spelt flour and 1 tsp salt. Mix until a shaggy dough forms, then knead on a floured surface for 8-10 minutes until smooth and elastic.
2. Step 2: Place dough in a lightly oiled bowl, cover with a damp cloth, and let rise at room temperature for 4-6 hours until doubled in size.
3. Step 3: While dough rises, heat 1 tbsp olive oil in a skillet over medium heat. Add 2 large thinly sliced yellow onions and 1 tbsp balsamic vinegar. Cook for 20-25 minutes, stirring often, until onions are deeply caramelized and sweet.
4. Step 4: Preheat oven to 475°F and place a pizza stone or heavy baking sheet inside to heat.
5. Step 5: Punch down dough and roll out on parchment paper to a 12-inch round. Sprinkle 1 tsp chopped fresh rosemary evenly over the surface.
6. Step 6: Spread caramelized onions over the dough, then evenly crumble 100 g goat cheese on top. Season with 1/4 tsp black pepper.
7. Step 7: Transfer pizza on parchment to the preheated stone or baking sheet. Bake for 12-15 minutes until crust is golden and cheese is slightly browned.
8. Step 8: Remove pizza, let cool for 5 minutes, slice, and serve warm.
