FAQs
1. Can I use bottled orange juice instead of fresh?
Fresh juice is best for flavor and balance, but bottled works if strained and unsweetened.
2. Can I make these cookies gluten-free?
Yes, substitute all-purpose flour with a 1:1 gluten-free blend.
3. Do I need to chill the dough overnight?
At least 4 hours is necessary, but overnight gives the best texture.
4. Can I use chocolate chips instead of chopped chocolate?
Not ideal—quality bar chocolate melts smoother.
5. Can I coat the whole cookie in chocolate?
Absolutely—many bakers prefer a full dip for indulgence.
