And I did. I tried at least a few times a month. I tried different oils. I tried paste instead of oil. I tried oven baked chips, I tried deep fried chips. I tried baking them in the oil, I tried adding the oil at the end, and in one particularly expensive experiment I tried both at the same time. My chips never tasted like truffle. I looked at recipe after recipe for truffle fries and I just couldn’t understand how the supposedly simple technique of making chips and then tossing them in truffle oil worked for everyone but me.
And then with the fourth truffle oil I tried, I realised the secret. The truffle oil needs to be really strong. A delicate and subtle white truffle oil, however lovely, is too weak to cut through. Black truffle oil with a highly concentrated flavour is your best bet. Not a lot of oil is going to stick to the chips- they already have a coat of oil they were cooked in- so it has to be potent for any flavour to stick.
The one I found that finally worked was Truffle Hunter‘s restaurant strength black truffle oil. It didn’t come cheap- but it is strong enough that only a small amount is needed, so very cost effective. It will keep truffle chips on the menu here for a very long time!
For this recipe, a deep fryer filled with sunflower or other vegetable oil is required. I have had successes with oven baked chips too and I will talk about that another day- but for real perfection, it doesn’t get much better than crispy twice cooked chips. Cooked once on a low heat, to fluff the insides, and again on a very high heat, to crisp the outsides.
- 4 medium potatoes
- Black truffle oil
- Grated parmesean cheese, optional
- Pre heat your fryer to 150C / 300F
- Cut your potatoes into chips- keep them as chunky or skinny as you like, but bear in mind that if they are particularly chunky or skinny it will affect your cooking times!
- Throw the chipped potatoes into the fryer, and cook for 10 minutes until they are a quite soft and soggy, but not too brown. Give the basket a shake halfway through to avoid them sticking together and cooking unevenly
- Remove the chips and let them cool down, atop some paper towel to soak up the excess oil
- Pre heat the fryer to 190C / 375F
- Place the chips back into the fryer for a further 4 to 5 minutes, until they are your preferred crispiness
- Throw the chips into a large bowl, sprinkle with salt and a drizzle of truffle oil. I haven’t given an amount- it really depends on how potent your oil is. If you have the strongest of oils, 1 teaspoon will do. If you have a milder one, you may need more.
- Toss the chips to ensure they are evenly coated with the salt and oil. Throw in the cheese now, if using.
- Dig in, use your hands, and lick your fingers when you’re done!
