Why is the batter purple and thick? Halfway through measuring, chemical reactions begin between the acidic components of the fruit and the leavening agents. Four teaspoons of baking powder demand immediate oven heat upon hydration. Delaying the bake causes carbon dioxide to escape into the air rather than lifting the flour structure. Fold the fresh berries in at the very final second with a gentle hand.
Fresh berries release water during baking. Tossing the fruit in a small portion of the three cups of flour creates a physical barrier that prevents sinking. The recipe specifies a generous 5x12-inch pan. Standard 8.5x4.5-inch loaf pans will overflow or remain raw in the center at 350 degrees F. Maintain an internal temperature of 200 degrees F before removing the loaf from the oven. Cool the baked item inside the metal vessel for precisely ten minutes before turning it onto a wire rack. Defying this cooling window causes the crumb to tear apart completely.
