Flavor profile

Romaine (cos) lettuce has a uniquely sturdy structure for a lettuce — the thick central rib retains its crunch even after washing and dressing, making it the best-performing lettuce in dressed salads that sit for any length of time. The outer dark-green leaves have more bitterness and less sweetness than the inner pale-yellow heart; romaine hearts (sold trimmed) provide the most balanced flavor. Caesar salad's design — assertive anchovy-garlic-Parmesan dressing against the crisp, slightly bitter romaine — exploits the lettuce's ability to stand up to a bold dressing without wilting or losing its character. Grilled romaine (halved hearts, charred cut-side down over high heat for 2–3 minutes) creates a smoky, partially wilted preparation where the inner leaves become tender while the outer leaves caramelize — served with Caesar dressing or anchovy butter it is a revelation. The crunch of romaine in a BLT or club sandwich is irreplaceable by softer lettuces.
