THUY Diem Pham is a chatterbox and a feeder, of the loveliest order. Attend one of her supper clubs and there might be five dishes on the menu but you're guaranteed to be served six or seven, the food appearing as she recounts stories of a childhood spent in Vietnam, walking barefoot picking "stinky but delicious" durian fruit, helping on her grandparents' farm and watching her mother make intricately layered broths.

Thuy (pronounced "Twee"), 36, moved to the UK aged seven, and three years ago quit a career in advertising to open a restaurant - and now has a cookbook to match too. The move into food began with being so inspired by restaurant meals that she'd go home and recreate them, while "pretending I was a chef on TV", followed by a series of supper clubs (she and her husband and business partner, Dave, would drag their sofa up to their bedroom to make space for guests) and a blog. Things went so well that they eventually launched The Little Viet Kitchen (LVK) in north London.

The plan was to share "dishes from my village, dishes my grandma made that didn't really exist anywhere else", and to do it in a way that meant when you walked into the restaurant, you felt you were "being hugged".

"If you went to a Vietnamese home, my goodness, love is all you would feel," says Thuy. "In our culture, we don't cuddle or give kisses, but we do it through food. That's what brings us together."

Part of her mission is to get people to taste "the wonderful flavours" she grew up with - "We were not rich in money, but we were so rich in the love through our food," she recalls - and underpinning her philosophy is the belief that "food really tastes better if you understand it".

Thuy explains: "In our home cooking, we don't follow recipes, we follow the flavour and watch the ingredients we have. So if a tomato is a really dark red, it means there's no need to put in as much sugar and salt, but if it's green and a bit yellow, then you know it's harder, it won't be as sweet, but it's got a lovely tang to it, which means you need to balance that out - that's what my mum taught me, and I've kept all those tips with me, and I'm using them every day when I cook."

But if you didn't grow up among a family of Vietnamese women with exacting standards - Thuy was 33 when her mum finally said her cooking was 'OK' ("I went crazy in the kitchen!" she remembers happily. "That's their way!") - who cooked food suffused with love, history, tradition and intuitive knowledge, you need a cookbook that'll show you the way. Hence Thuy's debut recipe collection, also called The Little Viet Kitchen.

From baked sea bass with lemongrass, chilli and ginger and sticky ribs, to caramelised coconut catfish and Vietnam's national dish, Pho (pronounced "fuh"), she acknowledges that it features some "really big recipes" - the kind you have to know if you truly want to fathom, and then master, Vietnamese cooking.

"They are time-consuming, but also real," she says. "We work and then we have 30 minutes to cook dinner, which is a shame, but the truth; save my book for the weekend, when friends and family come over, and actually spend some time in the kitchen."

You'll certainly need to set aside a day if you're to make her Pho, a shimmering broth laden with beef, fortified with oxtail and scattered with aniseedy Thai basil. "I spend too much time in the kitchen making broth," says Thuy lightly, with a woe-is-me grin, "but it's my kitchen, I'll do what I want."

In fact, she puts endless hours into her food, whether that means testing new recipes on her day off, or getting in at 1am from the restaurant and replying to all her social media comments before bed. "I look at my husband sometimes and I feel so bad - he's shattered, his life was great before he met me," she says with a huge laugh. "But it's so worth it."

Ask her what's going through her mind while she cooks, and she says: "I want to cook things that make me happy; when I'm cooking I want to transfer what I'm feeling. You hope that your flavours and your seasoning will have the power to make someone smile."

Then she adds: "I cook in fear a little bit - I just never want to become complacent. That fear makes me work harder and makes me taste everything 10 times. I stand at my pass and nothing goes out without me seeing that every detail on the plate is correct.

"That fear is because I want it to be perfect," Thuy concludes. "Cook with love - I know it sounds really corny!"

CARAMELISED SALMON AND GREEN PEPPERCORNS

A really quite decadent fish dish.

"I've chosen to use a non-traditional fish for this recipe because I wanted something readily available that wouldn't compromise the authenticity of the dish," explains chef Thuy Diem Pham.

"For me, salmon works wonderfully as the meat is perfectly moist with a firmer texture than white fish and, of course, it's absolutely delicious."

Ingredients:

(Serves 4)

500g salmon fillets

1tbsp vegetable oil

100g green peppercorns

250ml coconut water

For the marinade:

2tsp finely diced garlic

2 spring onions, white part only, finely diced

2tbsp soft brown sugar

3tbsp fish sauce

3tsp sesame oil

1tsp Caramel Sauce (dissolve 500g of granulated sugar in 125ml of water, add another 125ml water and cook until a rich dark reddish-brown colour)

To serve:

1 spring onion, sliced on the diagonal

1 or 2 red chillies, sliced on the diagonal

Crispy Fried Shallots (finely sliced shallots, deep-fried in vegetable oil until crisp)

Method:

1. Place the salmon fillets in a bowl, add the ingredients for the marinade, and mix together well. Leave to marinate in the fridge for three hours. Take out of the fridge 30 minutes before cooking to allow the salmon to come to room temperature.

2. Lightly scrape the marinade from the salmon. You are aiming to remove all the bits in the marinade without removing too much of the marinade sauce. Leave the salmon to one side and reserve the marinade for later use.

3. Heat the oil in a saucepan over a medium heat until it reaches 160°C. An easy way to tell when the oil is ready is to place a wooden chopstick into it - when bubbles form on the surface of the oil it is ready.

4. Add the green peppercorns and stir-fry for one minute. Place the salmon, skin-side down, into the pan and cook for three minutes until the skin is crisp. Flip the salmon over and pour in the marinade and coconut water (avoid pouring onto the salmon skin, otherwise it will lose its crispiness). Keep the pan on the heat for a further four minutes until the salmon becomes sticky and golden in colour. Keep the ingredients moving during this process, as you don't want them to burn, but avoid moving the fish as this could cause the fillet to break apart.

5. Now you are ready to serve. Carefully transfer the salmon to bowls with a little of the cooking liquid. Sprinkle with the spring onion, chillies and shallots. This dish is best served with rice and/or a side of vegetables.

Ingredients:

(Serves 2-3)

300g Asian broccoli, washed and dried

3tbsp sesame oil

6 garlic cloves, crushed

2tsp soy sauce

1tsp granulated sugar

1tbsp Chilli and Lemongrass Marinade (see below)

For the Chilli and Lemongrass Marinade:

(Makes approx 600ml)

200g dried shrimp

500ml vegetable oil

2tbsp finely diced garlic

10 spring onions, white parts only, finely chopped

1tbsp shrimp paste

1tsp dried red chilli flakes

2tbsp granulated sugar

1tsp salt

2tsp fish sauce

200ml chilli oil

vegetable oil

Method:

1. Make the marinade: Soak the dried shrimp for 30 minutes in a bowl of warm water. Drain, pat dry with paper towels, then blitz in a food processor for 30 seconds to form a fine floss and set aside. Heat the oil in a saucepan over a medium heat until it reaches 160°C. Add the garlic and the white parts of the spring onions, and fry for one to two minutes, or until the garlic starts to turn light golden in colour. Add the dried shrimp and shrimp paste to the pan and stir in the chilli flakes, sugar, salt and fish sauce. Reduce the heat to very low and cook for a further 20 minutes, stirring occasionally to stop the sugar from burning. Pour in the chilli oil and continue to cook for five minutes. Take the pan off the heat and leave the marinade to cool overnight, uncovered. Transfer to an airtight container or jar and pour over enough oil to cover the marinade mixture.

2. Bring one litre of water to the boil, and blanch the broccoli stems for 20 seconds then immediately submerge into a large bowl of cold water. Leave for 30 seconds, then take out and drain.

3. Heat the sesame oil to a medium heat in a small frying pan. An easy way to tell when the oil is ready is to place a wooden chopstick into it - when bubbles form on the surface of the oil it is ready. Add the crushed garlic, keeping it moving around the pan for approximately 10 seconds until the colour begins to change to a light brown.

4. Add the broccoli, soy sauce and sugar and toss for one minute, making sure the broccoli is coated evenly in the sauce.

5. Remove the broccoli stems from the heat immediately, ensuring it remains al dente, and plate.

6. Now drizzle over the chilli and lemongrass marinade and it's ready to serve.
