Notes

• Overnight chilling allows croissants to soak up egg mixture, creating a richer, more custardy texture.
• For a lighter version, swap whole milk for skim milk and use low-fat ham and cheese.
• Vegetarian adaptation works great by replacing ham with sautéed mushrooms or spinach.
• Room temperature ingredients blend more smoothly, so take eggs and milk out of the refrigerator 30 minutes before mixing.
