🔥 How to Blanch Parsnips (Step-by-Step)

Step 1: Bring Water to the Boil

• Fill a large saucepan with water
• Add a pinch of salt (optional)
• Bring to a rolling boil

---

Step 2: Add Parsnips

• Carefully add parsnips to boiling water
• Do not overcrowd the pan
• Keep water boiling

---

Step 3: Blanch for the Correct Time

✔ Small slices or batons: 2 minutes
✔ Chunks or cubes: 3 minutes
✔ Large pieces: 4 minutes

Do not overblanch — parsnips should be slightly tender, not cooked through.

Step 4: Cool Immediately

• Transfer parsnips straight into ice-cold water
• Leave for the same time as blanching
• This stops the cooking process

---

Step 5: Drain Thoroughly

• Drain well in a colander
• Pat dry with kitchen paper

Excess moisture causes freezer burn and sogginess.
