Banh Mi with Lemongrass Pork and Pickled Vegetables

Ingredients

• 500g pork mince (20% fat)
• 3 lemongrass stalks, tough outer layers removed, finely minced
• 4 garlic cloves, finely grated
• 1 small shallot, finely grated
• 2 tbsp fish sauce
• 1 tbsp light soy sauce
• 2 tbsp soft light brown sugar
• 1 tbsp vegetable oil
• 1 tsp coarse black pepper
• 1 tbsp vegetable oil, for frying
• 1 large carrot (about 150g), cut into matchsticks
• 200g daikon (mooli), cut into matchsticks
• 100ml rice vinegar
• 100ml warm water
• 3 tbsp caster sugar
• 1 tsp fine salt
• 1 cucumber, halved lengthways and cut into long batons
• 1 large bunch fresh coriander (leaves and tender stems)
• 1 small bunch fresh mint, leaves picked
• 1-2 red bird's eye chillies, thinly sliced
• 4 spring onions, thinly sliced lengthways (optional)
• 4 small Vietnamese-style baguettes (or 2 light French baguettes, halved)
• 4 tbsp mayonnaise (Kewpie if you have it)
• 100g smooth chicken liver pâté (or extra mayo if preferred)
• sriracha, to taste
• 1 tbsp Maggi seasoning or extra soy sauce, to splash

Method

1. Start the pickle first — it needs 30 minutes minimum and only gets better with time. Whisk the rice vinegar, warm water, caster sugar and fine salt in a bowl until the sugar has fully dissolved — taste it, it should hit sour-sweet-salty in equal measure. Add the carrot and daikon matchsticks, push them under the brine, and leave at room temperature for at least 30 minutes (or up to 3 days in the fridge). They're ready when they've gone limp and translucent — that's the raw bite gone and the sour-sweet flavour driven in.
2. Make the pork marinade. Combine the lemongrass, grated garlic, shallot, fish sauce, soy, brown sugar, vegetable oil and black pepper in a bowl. Add the pork mince and mix with your hands just until evenly combined — don't overwork it or the texture turns bouncy and tight. The fish sauce and soy carry most of the salt here, so trust the recipe and don't add more at this stage. Rest for at least 15 minutes while the pickle works, or cover and chill overnight for deeper flavour.
3. Set a large stainless or cast iron frying pan over medium-high heat with the tablespoon of vegetable oil until it shimmers. Add the pork in two batches in a flat single layer — crowd it and water comes out, and you've boiled the meat instead of caramelising it. Leave the first batch alone for 2–3 minutes so the underside develops a deep, lacquered crust — that's the brown sugar and garlic working, and stirring too early will steam it grey.
4. Break the pork up with a wooden spoon and keep cooking for another 4–5 minutes, watching the garlic closely — you want it bronzed and fragrant, not burnt, because burnt garlic turns the whole filling bitter. Cook until the edges are crisp and dark and the mince has proper colour. Taste a little — most of the seasoning is built in, but adjust now with a pinch of salt or an extra splash of soy if it needs it. Tip onto a plate and let it cool to room temperature. (If making ahead, cool fully, refrigerate, and bring back to cool room temp before building.)
5. Drain the pickle thoroughly in a sieve and give it a gentle squeeze — wet pickle makes soggy bread, and soggy bread is the death of a banh mi.
6. Split the baguettes lengthways without cutting all the way through. If the bread is soft, warm it in a hot oven for 2–3 minutes to crisp the crust, then let it cool completely — warm bread steams the herbs and wilts them inside the wrap.
7. Build each sandwich in order: spread mayonnaise generously on the top half and pâté on the bottom (the fat layer waterproofs the bread against the pickle juices). Lay in cucumber batons, then a heaped pile of pork, then a generous tangle of pickled carrot and daikon. Top with coriander, mint, sliced chilli and spring onion. Splash a few drops of Maggi or soy across the herbs, zigzag with sriracha, and taste a loose bit of filling — adjust seasoning one final time before you close the lid.
8. Press the lid down firmly. Plate up with extra sriracha on the side, prawn crackers, and lime wedges to squeeze over the open end just before biting — the squeeze of lime cuts through the pâté and mayo and pulls every flavour into focus. Pour the iced coffee or crack open a cold lager. If you're packing for a picnic, wrap each banh mi tightly in greaseproof paper, twisted at the ends like a sweet wrapper — they'll hold beautifully for 3–4 hours as the pâté and pickle juices marry into the crumb.
