FAQs About Lemon Brownies with Zesty Lemon Glaze

What does lemon do to baked goods?
Lemon adds brightness and acidity to baked goods, balancing sweetness and enhancing other flavors. The acid in lemon juice can also tenderize doughs and batters, creating a softer texture.

What does sour cream do for brownies?
Sour cream adds moisture and richness to brownies, making them extra fudgy and tender. The slight acidity of sour cream also helps activate baking soda for better rise.

How long to cook lemon brownies?
Lemon brownies typically bake at 350°F (175°C) for 23–25 minutes. Start checking at 20 minutes to avoid overbaking and maintain a moist, fudgy texture.

How many lemons for lemon bars?
You usually need about 3 to 4 medium lemons to get enough juice (around ½ to ⅔ cup) for a standard lemon bar recipe. Always use fresh lemons for the best flavor.

What enhances lemon flavor in baking?
Using both fresh lemon juice and lemon zest greatly enhances lemon flavor. A touch of pure lemon extract can also intensify the citrus notes without adding more liquid.

What does lemon juice do to flour?
Lemon juice can weaken gluten formation in flour because of its acidity, resulting in more tender baked goods. It acts similarly to how buttermilk or yogurt affects flour.

Can yeast survive in lemon juice?
No, yeast struggles to survive in highly acidic environments like pure lemon juice. The acid inhibits yeast growth and fermentation.

How does lemon juice thicken?
On its own, lemon juice does not thicken. However, when mixed with powdered sugar or used in curd or glaze recipes, its acid helps stabilize and slightly thicken mixtures.

Does lemon help baking powder?
Yes, the acidity in lemon juice can react with baking soda to create carbon dioxide, helping baked goods rise. Lemon enhances the leavening effect when combined with baking powder or baking soda.

Why are my lemon bars mushy?
Lemon bars can turn out mushy if they are underbaked, if the custard ratio is too high, or if they are not properly cooled before cutting. Always bake until the filling is set and chill thoroughly.

What to bake with lots of lemons?
With lots of lemons, you can make lemon brownies, lemon bars, lemon pound cake, lemon meringue pie, lemon poppy seed muffins, or homemade lemonade desserts.

How many lemons does it take to make 1 cup of juice?
It typically takes about 5 to 6 medium lemons to yield 1 cup of fresh lemon juice, depending on the juiciness of the fruit.
