今注目を集めている Can You Cook Romaine Lettuceについて、詳しいまとめを整理して公開しています。

Why doesn’t romaine turn into a slime monster like other lettuces? It’s because romaine is built like a tank. Its sturdy cell structure holds up to heat, while fragile iceberg or butter lettuce would wave a white flag and dissolve instantly. This is also why you can stir-fry bok choy but not wet spinach. Romaine is the Belgian Malinois of the lettuce world: tough, loyal, and surprisingly good at doing things other greens can’t.

Another fun fact: cooking romaine actually increases your body’s ability to absorb certain nutrients, like vitamins A and K. So by eating it grilled with butter, you’re basically being healthier than if you ate it raw with low-fat dressing. Science, baby.

A Word of Caution (For the Overachievers)

Do not, under any circumstances, try to boil romaine. That’s the one move that will ruin your kitchen cred. Boiled lettuce is what happens when you give up on life and let a vegetable drown in hot water. It turns into a sad, limpid mess that tastes like regret and warm lawn clippings. Don’t do it.

Also, avoid microwaving it for more than 30 seconds unless you want a sad, steamed version that reminds everyone of cafeteria lunches from 1993. Stick to dry heat—grill, sauté, or roast—and you’ll be a lettuce-cooking legend.
