The bread batter should be thick. If you find it to be on the runny side, add up to 1/4 cup of additional flour. Please note that fruits vary in their moisture content, and as a result, the consistency of batters will vary. Strawberries release water into the batter during the baking process, so it's better to have a thicker batter going into the oven. Use your best judgement.
Within the last 10 minutes of baking, loosely drape a piece of tin foil over the loaf to prevent the top and sides from becoming overly browned.
