🤝 Honourable Mention: Olive Oil (Use with Caution)

Only use:
If you don’t have any high-heat oils or fats available.

❌ Worst Oils for Christmas Roasties

❌ Butter

Burns easily → black bits, bitter flavour.

❌ Extra-Virgin Olive Oil

Smokes at low temps → soft potatoes.

❌ Coconut Oil

Strong flavour + weird texture.

❌ Low-Fat Sprays

Do not crisp properly.

❌ Sunflower Oil (for some ovens)

Lower smoke point than rapeseed oil.

🔥 How Much Fat Should You Use?

For proper Christmas crispiness:

👉 2–4 tablespoons per roasting tin

Hot fat should just coat the bottom of the tray — enough for a sizzle but not swimming.

🍽 How to Use Fat Correctly for Maximum Crunch

1. Put fat into the roasting tin
2. Heat in oven at 220°C until smoking hot
3. Add parboiled potatoes carefully
4. Turn until evenly coated
5. Roast for 45–55 minutes, turning once

This method works with all the fats listed above.
