Last night we made frenchfries in the deep fryer. We then fried chicken, which took about 20 minutes.

During that time, we put the fries in the oven on low temperature to keep them warm.

Bad move...totally soggy and disgusting.

What should we have done?

Take the chicken out of the fryer, let it "rest" and then do your fries. Fries are quick!

Or reheat in oven at much higher temperature. It's worked when we've reheated take-out fries in the oven.

Do the french fries first AND last using the two step frying method. See:

Yeah, we already do the 2-step frying method. We should have split it up, but didn't think of it.

Next time, for sure.

try cooking the chips twice, once to cook the insides (on lowish heat) then once to crisp them (on high heat). Cook chicken in between, and rest chicken for about 10 minutes.

First of all, you need the right kind of potatoes. Some are not good for deep frying, like new potatoes. The oil has to be hot, and do the fries in small batches to avoid dropping the temperature drastically, which will result in soggy, greasy fries. Take the fries out while you do other things, then put them back in for a minute at the end. When they are done, shake off extra oil and dump them onto paper towels or newspaper to sop up the rest of the grease.

Next time, fry the chicken first, then the french fries.

Chips

I had to do this recipe eventually, not least because I really believe that these are the best chips in the world. I've spent years looking for the perfect chip, along the way experimenting with just about every possible variable: the oil, the number of cooking processes, the type of potato, temperature, etc. The traditional way to make chips is with two separate cooking processes, not least because if you try to fry the chips in one go, they go brown before the inside has the time to cook. An initial, cooler fry enables the potato to be cooked through, ready for browning in very hot oil later. For me, the perfect chip has a wonderfully crisp exterior and a light, fluffy interior.

We had a problem a while back at the restaurant, in that the meat (a veal kidney) we were serving with chips had to be cooked to a far lower temperature than the chips, so although the meat was at the ideal temperature when served, the chips, being so hot, would make the meat seem cool even when it wasn't. As a result, I set myself the task of coming up with a chip that would keep its crunch for several minutes so that it could be served nearer to the temperature of the meat. I tried many variations, until eventually settling on this recipe.

I also thought long and hard about why chips lost their crunch. Basically, when you cook the chip for the last time, the moisture held in the soft interior turns to steam. This steam wants to evaporate, so penetrates the crisp exterior, and therefore softens it. The solution, then, was to reduce this evaporating moisture, and the easiest way to do this, I thought, was to reduce the moisture levels in the potato. To do this, we tried several things.

Drying the chip in the oven between each cooking process made the chip too dry and almost tough, and it also lost its wonderfully fluffy interior. Pinpricking the chip as soon as it comes out of the water in the first cooking, allowing steam to escape more easily, worked pretty well, but the thought of stabbing each chip nearly 25 times was a little impractical, to say the least.

I then discovered a desiccator. This is a container with a valve on the side that can be fitted to a pump. When the pump is on, it sucks air and, with it, excess moisture from whatever is inside it, particularly when the food is put in it while still warm. Placing the chips in this vessel in between each of the cooking processes drew out just the right amount of moisture to prevent excess steam from building up during the final cooking process. The only downside is that, as the chip cools during the second of the three cooking processes (the first time that it is cooked in fat), some of the fat left on the chip when it is removed from the oil is absorbed. As the chip cools, the outward pressure caused by the steam inside the chip dies down - because it is this pressure that prevents the fat from being absorbed in the first place, the cooling chip absorbs the fat.

I did try cooking the chip by placing it in warm oil and gradually increasing the temperature so that the potato gradually cooked and browned at the same time. Although this meant that the chip absorbed little fat, it did not come out as crisp. The following recipe by no means leaves the chips fatty - but, to my mind, if you are at all worried about any of this, cook something else instead.

The only other thing to say about cooking chips is that the potato you use makes a huge difference. For me, nothing can beat the Golden Wonder potato, but it is pretty difficult to obtain; Maris Piper and King Edwards work well, too.

There is no need to give quantities for this recipe, not least as I'd hate to be blamed for short-changing you on the number of fabulous chips you will end up with. Just make sure that you have your fryer filled to the correct level.

Brand new oil is not always the best to use. If you do decide to make chips on a regular basis - and, believe me, having tried these, you will - save a little of the old oil in the fryer to add to new oil. This helps prevent the chips from scorching.

So, let's make chips. Wash, peel and cut the potatoes into chip lengths. Don't worry if they're a little uneven, because this means that you'll get a range of textures, from thicker, luxuriant, fluffier chips to more crisp-edged pieces.

Place the cut chips in a bowl of cold water and, when you have finished cutting them all, leave the bowl under the cold tap for five minutes to remove excess starch. Bring a large pan of unsalted water to a simmer and drop in the chips. Cook until the potatoes are soft, ideally to that point just before they start falling apart. With a slotted spoon, carefully lift out the chips and place on a tray, board or, best of all, a cake rack, then leave to cool. Once cool, place in the fridge for at least half an hour.

Preheat the fryer to 130C. Cook the cold chips at this level until they take on a dry appearance on their surface - you don't want them to colour at all. Drain, and leave to cool again. When cool, refrigerate again for at least half an hour.

Increase the temperature of the oil in the fryer to 190C. Plunge the cold chips in this and cook until golden brown and crisp. Drain, salt and serve at once.
