01

How to select romaine

Look for a head that feels heavy for its size, with upright leaves and firm, pale ribs. Outer leaves can be deep green and slightly relaxed, but they should not be slimy, heavily bruised or yellowing at the edges. The cut base should look clean rather than dark and dried out.

Whole heads usually offer better texture and longevity than pre-cut leaves. Romaine hearts are convenient and sweet-crisp, while full heads give you darker outer leaves with a little more bitterness and character.

02

Wash—and dry it completely

Pull the leaves from the core and discard any damaged outer ones. Rinse each leaf thoroughly under cool running water, rubbing gently and paying attention to the cupped base where grit collects. A clean bowl of cold water can help loosen stubborn grit, but finish with a running-water rinse. Do not use soap, detergent or commercial produce wash.

Spin in small batches until no water collects in the spinner. Lay the leaves on a clean towel and blot the ribs and folds. Dressing adheres to a dry leaf; on a wet one, it slides off and becomes diluted.

03

Cut, tear or keep whole

Tear for mixed salads: broad, irregular pieces catch dressing without exposing too many wet cut edges. Slice crosswise for chopped salads: keep the pieces at least 2–3 cm wide so the rib still supplies crunch. Keep inner leaves whole: the smallest leaves make excellent scoops and echo the commonly described early presentation of Caesar Salad.

For grilling, halve compact hearts lengthwise through the core so the leaves stay attached. A fast sear adds smoke while the center remains crisp.

04

Storage without sogginess

Keep romaine refrigerated at 4°C / 40°F or below. For better quality, store an unwashed whole head loosely wrapped in a breathable or partly open bag in the crisper drawer. If you wash ahead, dry every leaf thoroughly, wrap the leaves in a clean dry towel, and place them in a container with a little room for air. Replace the towel if it becomes damp.

Keep romaine away from crushing produce and inspect it before use. Trim a dry cut end, and discard leaves that look rotten, are slimy or show extensive decay. Those are rejection cues, not proof that apparently normal leaves are free from contamination.

05

Dressings and ingredients that suit it

Romaine is especially good with emulsified dressings: Caesar Dressing, buttermilk dressings, tahini-lemon sauce and mustard vinaigrette. Its ribs can take garlic, anchovy, aged cheese and pepper without disappearing.

Rich & savory

Parmesan, feta, blue cheese, eggs, roast chicken, tuna, chickpeas.

Sharp & bright

Lemon, capers, pickled onion, radishes, tomatoes, fresh herbs.

Crunch on crunch

Croutons, toasted seeds, almonds, cucumber, celery, fried shallots.

06

Reasonable substitutes

Little gem is the closest substitute: compact, sweet and crisp, though smaller. Iceberg brings excellent crunch but less leafy flavor. Escarole offers sturdiness with more bitterness. For a modern Caesar variation, mature kale can work after the ribs are removed and the leaves are massaged with dressing, but it creates a distinctly different salad.
