How it works
Blanching involves briefly cooking vegetables in boiling salted water. The salt seasons the veg from within and helps maintain a firm texture. The boiling water rapidly heats the greens, setting their colour and softening fibres without turning them mushy. Timing is crucial: cook just until the greens are tender but still crisp to the bite. Overcooking will dull the colour and degrade texture. Once the greens have blanched, they must be shocked immediately in an ice water bath. This sudden temperature drop stops the cooking process instantly, preserving the bright colour and fresh texture. Without shocking, residual heat continues to cook the veg, leading to a limp, dull result. The ice bath also firms up the greens, making them easier to handle and store. After shocking, drain the greens thoroughly and pat dry to avoid a watery finish when dressed. At serving, finish with a drizzle of good oil, a pinch of salt, and a splash of acid such as lemon juice or vinegar to enhance flavour and balance. This technique is ideal for prepping greens ahead of time, allowing you to finish and serve them quickly without sacrificing quality.
Best for
- Bright, vibrant greens
- Prep-ahead side dishes
- Tender leafy vegetables
- Maintaining colour in vegetables
- Quick finishing of cooked greens
Common mistakes
- Under-salting the blanch water, resulting in bland vegetables
- Not cooling the greens quickly enough, causing overcooking and colour loss
- Failing to dry vegetables before dressing, leading to a watery finish
- Leaving greens in ice water too long, which can make them waterlogged
- Blanching for too long, resulting in mushy texture
