How to Blanch Vegetables
Blanching is the bridge between raw and cooked. It is the best way to handle seasonal vegetables so they retain their character without turning into mush.
Control the temperature, keep the crunch.
The goal is to stop the cooking exactly when the color reaches its peak brightness. Have your ice bath ready before the water hits a boil.
- Large stockpot
- Spider strainer or slotted spoon
- Large mixing bowl for ice bath
- Clean kitchen towel
What goes in.
- 1 lbVegetables, cleaned and cut to uniform size
- 2 tbspKosher salt (for the water)
- 2 traysIce cubes
Thermal arrest
The cold water bath is not optional. It stops the residual heat from continuing to cook the vegetable from the inside, preserving the internal texture.
The method.
Prepare the ice bath
Fill a large bowl with cold water and two trays of ice. Set it right next to your stove.
Boil the water
Bring a large pot of water to a rolling boil. Add the salt; it should taste like seawater.
Cook
Drop the vegetables into the water. Green beans take 2–3 minutes; snap peas take 1 minute; carrots need 3–4 minutes. Watch for the color to intensify.
Shock
Use the spider strainer to lift the vegetables directly into the ice bath. Leave them until they are completely cool to the touch.
Dry
Drain the vegetables and spread them on a clean kitchen towel. Pat them dry thoroughly before storing or serving.
Other turns to take.
Asparagus
Blanch for 2 minutes. Focus on the stalks, ensuring they are firm but have lost their raw, woody bite.
Broccoli florets
Blanch for 3 minutes. The florets will turn a vivid, deep green when they are finished.
When it doesn't go to plan.
Work in small batches to keep the water temperature steady.
If the water loses its boil when you add the vegetables, wait for it to return to a boil before starting your timer.
Taste as you go; a blanched vegetable should feel tender but still have a distinct, crisp resistance to the tooth.
The ones that keep coming up.
Can I reuse the boiling water?
Yes, you can blanch several batches of the same vegetable in the same water. If the water gets cloudy or foams excessively, discard it and start fresh.
Why did my green beans turn grey?
They were in the boiling water too long. Blanching should be fast. If they lose their bright green color, they are overcooked.
