Heston Blumenthal triple cooked chips are a great way to cook chips at home for a real treat. They are not difficult but take a little time.

I’m sure like many Brits chips have evocative memories; for me they split two ways. The first is good ol’ fish and chips, eaten from paper along Southend seafront, stained with vinegar and gritty with salt, chilly breeze from the sea in the air. The other memory is of my Nan’s chips. She would peel the potatoes, chop them into chunky pieces (we’d call them wedges these days) and deep-fry them from raw until nearly dark brown. It doesn’t sound great but they had a thick crust and packed a potato punch, and I miss them terribly.

Fast-forward a little and I’m gazing down at Heston’s triple cooked chips. They’ve taken a while to do (as do most of his recipes) but the proof is in the eating: a brittle brown crust, golden skin and that cheeky deep-fried smell. The flesh inside is giving and fluffy – exactly what you want. They are, as you expect from the man, perfect.

There’s a little faff involved, but the ingredient list is very short.  It isn’t a difficult recipe by any stretch – the hardest thing is finding enough space in your fridge or freezer to stash them. First the sliced potatoes are par-boiled on a gentle heat, then deep-fried, then deep-fried again. Between each stage the potatoes are chilled and dried out thoroughly. Removing as much water as possible is crucial to drying out the chip; this ensures maximum crispiness. It may be a lot of stages but one big advantage to this method is that you can stop and refrigerate the chips at any step until needed, so all the legwork can be done well in advance if needed. When it comes to frying I’ve used a deep saucepan filled a third with oil; I’ve owned two deep fat fryers in the past. One just plain stank, the other melted. Yes, melted. A bit of a drawback for a deep fat fryer. My current one I’ve had for ten years, appropriately enough the Sage by Heston Deep Fat Fryer (now discontinued I believe). I keep it in the garage to limit the smells and noise.

You can read his recipe in either In Search of Total Perfection (as part of fish and chips) or Family Food: A New Approach to Cooking (Penguin Cookery Library). The only discrepancy between the recipes is the boiling stage; one says to salt the water, one not to. I decided to go with instinct and as if they were roast potatoes, salted them.

You can also find variations of this recipe at The Fat Duck’s site, the Michelin site, Kavey EatsThe Times, or Tom Kerridge’s take on them.

  • 1 kg Maris Piper potatoes


  • Sliced the potatoes into 2cm thick chips. Don't be too fussy about this; uneven things are charming. Rinse the potatoes well under running water to remove excess starch from the surface (this will stop them clinging together in the fat).
  • Plunge the chips into salted boiling water and reduce the heat to a simmer. This will ensure the middle is cooked thoroughly before they turn into mush. This is important to take it as far as you dare. Remove from the water when a knife point slides in easily - this will take about 20 minutes.
  • Drain the chips well and put in a single layer on a tray or on a wire rack. Put into the freezer for 30 minutes to completely dry them out.
  • Bring a plain oil (e.g. rapeseed) to 130°C - use a probe or sugar thermometer to achieve this. Drop the chips in and fry until they turn a very pale yellow and as Heston says, "have a dry appearance". It's an odd description but you'll know it when you see it. Don't let them turn brown. This will take 10 minutes.
  • Drain again, bake on the tray and back in the freezer to dry out.
  • Bring the oil up to 180°C. Chips back in, now let's get them coloured. Keep them in there until you get a nice dark brown on the edges. This will take 6 - 10 minutes depending on the starch content of your potatoes. When done drain thoroughly and chuck on Maldon sea salt - they can take quite a bit.
