FAQs
Can you taste the zucchini?
Not really! Zucchini blends in and doesn’t taste “vegetable-like” at all.
Should you peel the zucchini?
Nope — the peel is soft and adds nutrients and a touch of green color.
Can you use frozen blueberries?
Yes, but toss them in flour and don’t thaw them first to avoid excess moisture.
Why is my bread soggy in the middle?
Too much zucchini moisture or underbaking. Always test with a toothpick.
What does lemon zest do in baking?
It adds brightness and enhances the flavor of other ingredients, especially fruits.
Final Thoughts
