Crisp-tender

Crisp-tender describes vegetables cooked until they are hot and bright in color and soft on the outside, but still firm with a little crunch in the center. It is the vegetable version of al dente. Recipes ask for it with green beans, broccoli, asparagus, snap peas, carrots and peppers, especially in stir-fries and salads.

How to do it

1. Cut vegetables into even pieces so they cook at the same speed.
2. Steam, blanch, sauté or stir-fry them over high heat.
3. Start testing early. Typical times in boiling water or steam:
   • Asparagus, snap peas, snow peas: 1 to 3 minutes.
   • Green beans, broccoli florets: 2 to 4 minutes.
   • Carrot slices, cauliflower florets: 3 to 5 minutes.
4. Lift them out as soon as they pass the test.
5. For salads or to cook ahead, plunge them into ice water to stop the cooking, then drain well.

How to tell it is done

• The color has turned brighter and deeper, not dull or olive.
• A knife or fork goes in with a little push, and you feel resistance in the center.
• When you bite one, the outside is tender and the middle still snaps.

If the knife slides in with no resistance at all, the vegetable is fork-tender, which is a step further.

Why it works

Heat softens the pectin that holds plant cells together, starting from the outside. Stopping early leaves a firm core. Short cooking also keeps green vegetables bright, because their color dulls with long cooking, especially in acid.

Common mistakes

• Walking away. These vegetables go from crisp to soft in a minute or two.
• Forgetting carryover heat. Hot vegetables keep cooking in a covered dish. Take them out a little early or shock them.
• Uneven pieces. Some turn mushy while others stay raw.
• Adding lemon juice or vinegar long before serving. Acid turns green vegetables gray.

In recipes

"Cook until crisp-tender" and "tender-crisp" mean the same thing. If a recipe says "until just tender", it means slightly softer.
