Chef Tips from the Video
- Clarified butter or ghee gives a higher smoke point, preventing burnt flavor.
- Press the croissant gently with a spatula while toasting for even browning.
- Add a pinch of sea salt to the mayo for a subtle flavor boost.
Troubleshooting
Croissant halves are soggy instead of crispy.
Make sure the butter is fully clarified and the skillet is hot enough; toast a little longer on low heat.
Butter burns and gives a bitter taste.
Reduce the heat immediately and remove the pan from the burner; clarified butter should stay clear, not brown.
Storage
Refrigerator: Wrap tightly in plastic wrap; will keep up to 24 hours but will lose crispness.
Freezer: Not recommended – texture of croissant deteriorates.
Room temperature: Best eaten immediately; can sit up to 1 hour but will become soggy.
Make-Ahead Tips
- Slice croissants and store in an airtight container.
- Prepare clarified butter ahead of time and reheat gently before toasting.
- Keep mayonnaise separate until just before assembly.
