I can’t take credit for this recipe, although I wish I could. Heston Blumenthal is a “gastronomist” which means he uses science in his cooking. He uses it to match flavours, and to work out how best to cook something. Some of his stuff is a little over complex, but in this case all you need is time. Honestly, these chips do take quite some time to cook, but if you do it right, it’s damn well worth it.
Start with your potatoes. I still have no idea how to judge how many potatoes I need per person until I cut them up. Peel your potatoes and cut them into chips the way you like them. The first tip here is to not cut them too finely. The chunkier they are, the better this cooking technicque will work.
Boil the pre-cut chips. You can do it on the stove if you like, but I put boiling water in a microwave container and cook them in the microwave (sorry Heston). You want them to cook until they are ALMOST falling apart – but not. The more they are cooked, the lighter and fluffier the potato will be, but you need them to hold their shape.
Once they’re cooked, lay them out to cool. Make sure that the chips aren’t touching each other. Use a cooling rack or chopping board or another tray. They need to cool completely, so putting them in the fridge is a good idea. You really want them to go a bit cold, not just stay at room temperature.
Once they are cooled, get a wok or deep frier and get the oil HOT. Cook the chips in batches and set them to cool again, this time on paper towel to soak up the oil. The best chips are double-cooked, and that’s what we’re doing here. That means you can prep the chips to this stage ahead of time and do the second cook just before you serve.
There is a bit of a trick to the first cooking stage. Heston is so precise, he stipulates what temperature the oil should be for each cooking stage, but I can’t do that. I’m sure if you head over to his website, you could probably find the temps, but my chips are pretty damn good without going the full monty.
When you cook the chips the first time around, you don’t want to cook them completely. You need them to START going golden brown, but not fully cooked. When you cook them the second time, they will cook quickly and brown-up even quicker. All you’re really doing here is crisping up the outside a bit to hold the fluffy potato together.
Right, so once the chips are all cooked, set them to cool again, even putting them back in the fridge if you want. Make sure they go below room temperature again before cooking them for the second time.
Reheat your oil and get it hotter than the first stage, if you can. Cook the chips again until they are the perfect golden brown colour, then take them out, put them on a board and salt them while they are still hot, and while they still have some residual oil on them. Then serve them ASAP while they’re still super hot. These chips are the perfect accompaniment to my steak recipe.
If you follow this process completely, and you’re cooking chips for a family of four, it could take around three hours in a home kitchen. I told you it was time consuming, but let me just say that the chips are F**KING AWESOME. Perfectly crispy on the outside, perfectly fluffy in the middle. The first time I did these, it took me all morning, and we had them with lunch at 1pm.
My family loved them and asked for more – but of course there was no way in hell I was doing it all again before dinner. You can cut this time down a bit by not letting the chips cool completely between each stage. Boiling them takes about five minutes in the microwave, and each frying stage takes about 10 minutes, so it’s possible to achieve a B grade version for any meal. Just remember to ALWAYS double-cook your chips. It’s the only way to get crispy outside, fluffy inside.
