Since all the methode rotuts was gone, today was more blueberry pancakes. This time I removed all the butter and increased the sour cream. I also decreased the salt:
90 g cake flour
90 g AP flour
225 g whole milk
2 large eggs
4-6 Tablespoons sour cream
1/4 teaspoon Kosher salt
blueberries (reserved)
Best yet. Butter gets in the way of blueberries. I still think the batter can be thicker, so I'll plan to reduce the milk next time. But I need more bacon.
