This recipe, from Pippa Middlehurst’s ‘Dumplings and Noodles: Bao, Gyoza, Biang Biang, Ramen and Everything in Between’ produces delicious noodles.
- 1g kansui
- 198g high-gluten flour, such as extra-strong bread flour
- 86ml water
- Potato starch or cornflour (cornstarch), for dusting
- 1g salt
To make the kansui:
- Preheat the oven to 120C/250F/Gas 1/2. Sprinkle 100g (4oz) bicarbonate of soda (baking soda) onto a foil-lined baking tray and bake in the oven for 1 hour.
- As it heats, the sodium bicarbonate changes into sodium carbonate, an alkali salt that can be used to change the pH of the noodle dough and make it firmer.
- Remove the kansui from the oven and transfer to a clean airtight jar by making a crease in the foil and pouring it into the jar (taking care to avoid contact with your skin as your pour). Seal with a lid and use the kansui as directed below. The powder will keep for up to a month. Don’t leave the jar open for too long, allowing the kansui to come into contact with the air, or it will absorb moisture and be less effective.
To make the noodles:
- Combine the flour and kansui in a mixing bowl with the salt and 86ml water and combine until the mixture forms rough pieces. You can use the paddle attachment on a stand mixer to do this.
- Once dry straggles start to form, bring the dough together into a ball. Apply pressure using the palm of your hand in a downward motion and continue to do this until the straggles of dough are forced together to form a rough ball.
- Cover the bowl with a clean, damp tea towel and leave it to rest for 15 minutes. In the meantime, set up your pasta roller, clamping it firmly to the worktop as the dough is extremely hard.
- Remove the dough from the bowl. Take a rolling pin and press firmly onto the dough, section by section, until it is thin enough to pass through the pasta roller on its widest setting, then feed the dough through the roller. What will emerge may be quite rough and ragged, but this is ok. If the sheet has separated, or holes have appeared, don’t worry. Pass the dough through again on the widest setting and repeat this step until you have one complete sheet of dough, with no holes.
- Reset the pasta roller to the next narrowest setting and repeat this step until you have one complete sheet of dough, with no holes. Reset the pasta roller to the next narrowest setting and pass the sheet of dough through, then reduce the setting once more, to the third narrowest level, and feed the dough through a final time.
- Now fold the dough in half, lengthways, and pass through the pasta roller on the widest setting. Repeat this sheeting and folding process until you have a smooth and even-textured sheet of dough. The edges of the sheet may have become dry and cracked during folding, but this is ok.
- Gently fold your sheet of dough in half and leave to rest for 30 minutes, covered with a tea towel or cling film.
- Once the dough sheet has rested, unfold it and pass through the pasta roller to the final desired thickness, before cutting the dough into noodles. On my pasta roller, this is number 4 for a thick noodle, number 5 for a medium noodle and number 6 for a thin noodle. The thickness of your noodle will be dictated by the recipe you plan to use it in.
- To create your noodles, pass the dough through the cutting attachment. Lightly dust the noodles with potato starch or cornflour (cornstarch) to keep the strands separate. Ramen noodles get better with age – resting them for 24 hours will improve the texture. They are good for up to 5 days in the fridge, but can also be enjoyed straight away.
- Cook the noodles in a pan of boiling salted water until al dente (between 1 ½ minutes and 2 minutes, depending on their thickness). Rinse in cold water and serve in your chosen recipe.
