Béchamel Sauce
Béchamel is the quiet trick that makes a croque madame feel lush instead of dry. Whisk the milk into the roux slowly and it turns smooth and spoonable, thick enough to coat without going gluey.

Notes
- Roux Ratio: Equal parts butter and flour create a smooth, balanced roux. The butter amount is adjusted here to 2 tablespoons so the sauce cooks properly.
- Warm Milk: Warm milk blends into the roux more smoothly and helps prevent lumps.
- Do Not Brown the Roux: Béchamel should stay pale. Cook the roux only long enough to remove the raw flour taste.
- Consistency: For a thinner sauce, whisk in a little extra warm milk. For a thicker sauce, simmer a minute longer.
- Dry Mustard: Dry mustard gives the sauce a subtle sharpness that works especially well with cheese, ham, eggs, and baked dishes.
- Storage: Refrigerate in an airtight container for up to 3 days. Reheat gently over low heat, whisking in a splash of milk if needed.
- Serving Suggestions: Use with Croque Madame, baked pasta, vegetable gratins, casseroles, creamed vegetables, breakfast sandwiches, or baked eggs.
