The secret to perfect cookies lies in the details. Let the dough balls spread naturally during baking without pressing them down. Well-toasted hazelnuts provide the best flavor. Adding toppings while the cookies are still warm ensures they adhere properly and creates an appealing finish.
Frequently Asked Questions
- → Why should hazelnuts be roasted?
- Roasting enhances the flavor of hazelnuts and makes them crispier. Plus, it helps remove the bitter skins easily.
- → Can I prepare the dough in advance?
- Absolutely! You can chill the dough in the fridge for up to a day, or even freeze the unbaked dough balls for a month.
- → What’s the purpose of using buckwheat flour?
- Buckwheat flour gives a unique taste and texture to the cookies. Its nutty, toasted notes pair so well with chocolate.
- → How do I know when the cookies are done baking?
- Check for slightly golden edges while the center remains soft after about 11 minutes. They’ll firm up as they cool on the rack.
- → Can I swap out dark chocolate for another type?
- Sure, you can use milk or white chocolate if you prefer. Dark chocolate, however, brings a nice contrast to the sweetness of hazelnuts.
