Grilled Beef Tenderloin Crostini with Béarnaise Sauce

## Culinary Tips for Success

* **Choosing Beef:** Opt for high-quality beef tenderloin. You can also use filet mignon medallions or sirloin tips for a different texture.
* **Temperature Control:** Use a meat thermometer to ensure your beef is cooked to perfection—medium-rare is recommended for tenderness and juiciness.
* **Béarnaise Sauce Troubleshooting:** If your sauce breaks (separates), whisk in a teaspoon of cold water slowly to bring it back together.
* **Make Ahead:** Béarnaise sauce is best made fresh, but can be kept warm in a thermos for a short period. Crostini and beef are best prepared just before serving.
* **Bread Selection:** A French baguette is ideal, but ciabatta or sourdough can add a different flavor profile.
