How To Make Nigella Ruby Noodles
- Boil Water for Pasta: Bring a large pan of salted water to a boil.
- Prepare Beetroot Base: In another pan, combine beetroot juice, juice of 1 lime, garlic, ginger, salt, and chilli flakes. Simmer gently.
- Cook Pasta in Two Stages: Boil spaghetti in water for 5 minutes, then transfer to beetroot pan. Cook until al dente (5–8 mins), adding hot water if needed.
- Dress and Cool: Off heat, stir in 2 tsp sesame oil, 2 tsp fish sauce, 1 tsp vinegar, and 2 tsp soy sauce. Toss and cool in a shallow bowl.
- Finish with More Dressing: Mix juice of ½ lime, remaining sesame oil, vinegar, fish sauce, and soy sauce. Pour over noodles and toss.
- Add Herbs and Serve: Toss with chopped coriander and chives. Taste and adjust with lime or salt as needed.

Recipe Tips
- Use Tongs While Cooking: Prevent sticking as spaghetti absorbs beet juice.
- Make It Cold or Hot: These noodles shine either way, but develop bolder flavors cold.
- Add More Lime: Balance sweetness of beetroot with extra citrus if desired.
- Rehydrate Leftovers: Use sesame oil and soy to freshen up stored noodles.
What To Serve With Ruby Noodles
Ruby noodles pair beautifully with grilled tofu, pan-seared salmon, or as a vibrant side to Asian-style pork or chicken. A crisp cucumber salad or pickled vegetables complete the plate nicely.
How To Store Ruby Noodles
Refrigerate: Store in an airtight container for up to 3 days. Toss with a little oil and soy before serving.
Freeze: Not recommended due to texture changes after freezing.
