Chef Tips from the Video

  • Add a pinch of salt to the batter to enhance the sweet flavor.
  • Use slightly warm water (30 °C) to speed up the action of the baking powder.
  • Dust the waffles with powdered sugar just before serving for an elegant visual effect.

Troubleshooting

Lumpy batter

Sift the flour and incorporate the eggs slowly, add the water in a stream while whisking vigorously.

Bubbles do not inflate

Ensure the waffle iron is properly preheated to 200 °C and do not overload the mold.

Waffle sticks to the mold

Lightly grease the mold with a little oil or use cooking spray.

Storage

Refrigerator: Store the uncooked batter for 1 day in the refrigerator, covered with plastic wrap.

Freezer: Cooked waffles keep for 1 month in the freezer in an airtight bag.

Room temperature: Ungarnished waffles can be kept for 2 hours at room temperature, but they lose their crispness.

Make-Ahead Tips

  • Prepare the batter the day before and keep it in the refrigerator; it will develop more bubbles.
  • Form the paper cones in advance and store them in an airtight container.
  • Melt the chocolate in advance and keep it in a bain‑marie.
