Relying on a thermometer inside a dense quick bread often yields false readings due to pockets of fruit. Instead, watch the edges carefully. The loaf is fully baked when the crust pulls slightly away from the metal pan walls. Insert a wooden skewer directly into the geometric center. If the skewer emerges with wet batter attached, continue baking in five-minute increments. Crumb resistance also indicates readiness. Press the top firmly with a fingertip; the surface must spring back instantly rather than leave a depression.
Frozen raspberries introduce excess moisture into standard quick bread batters. Do not thaw the fruit before folding it into the mixture. Keeping the raspberries frozen prevents the pigment from bleeding entirely into the surrounding batter. Toss the frozen berries in a small portion of the measured flour before incorporating them. This coating creates a barrier that suspends the fruit evenly throughout the crumb during baking.
Unglazed loaves freeze exceptionally well for up to three months. Wrap the completely cooled bread tightly in plastic wrap, followed by a layer of heavy-duty aluminum foil. Thaw the wrapped loaf overnight at room temperature before applying the fresh lemon glaze. Applying citrus glaze to a warm surface causes the powdered sugar to dissolve into a translucent syrup rather than setting into a crisp crust.
