Tom Aikens shares his secrets for the perfect fish and chips.
Serves 4
For the Batter
300g high gluten bread flour
1½ tsp salt
60g cornflour
15g sugar
¼ tsp white pepper
500ml Heineken lager
30g yeast
For the Tartare sauce
10g English mustard
Pinch freshly ground black pepper
1 tsp salt
4 egg yolks
750ml vegetable oil
2 tbsp water
1½ tsp lemon juice
3 tsp white wine vinegar
75g chopped gherkins
75g chopped capers
10g chopped parsley
75g chopped shallots
For the Thick cut chips
Maris Piper potatoes, peeled
Oil, for frying
Method
Batter: Place the flour and salt in a bowl and make a well. Mix the remaining ingredients and leave to stand for a good 10 minutes. Pour the liquid into the flour and whisk to a batter. It needs to be whisked very well to avoid any lumps. As this batter is a beer batter, it's best used after 15-20 minutes. If you don't want to use all beer, then mix half beer and half sparkling mineral water. This will help with the crispness of the batter.
Tartare sauce: whisk the mustard, salt, pepper and egg yolks in a bowl then slowly pour in the oil, whisking well. You will need to add a little water to the mayonnaise to stop it getting too thick and splitting. Then carefully whisk in the rest of the ingredients.
Chips: cut the potatoes into 1cm square batons the length of the potato so they are all the same size. Wash the starch off the potato with cold running water. Place into a pan of slightly salted cold water and bring to a rapid boil. Then chill them straight away in cold water to stop them cooking any further. Dry them off well and then plunge them into the hot oil at 140C for 2-3 minutes, then drain. Heat the oil back up to 180C. Then plunge them back into the oil till they are golden brown - approximately 3-5 minutes - then drain and season with sea salt.
To fry the fish, dust the fish with the flour then dip into the batter and fry at 180C until crisp and golden.

Follow Tom's tip for chips: "You will only have problems with the frying if the oil is not hot enough as they will not colour properly or go crisp, but rather soggy. When we cook the chips three times they will take on some of the water when they are blanched, which not only helps the fluffiness of the potato, but also helps the potato becoming crisp and they have started to cook from the inside. When they hit the oil for the first time, they are cooking instead of being blanched. So for the last fry, they then become crisp. And use Maris Piper potatoes from Lincolnshire".
