Why Panang and Mussels Work So Well
Mussels have a naturally sweet, briny flavour that pairs beautifully with the rich warmth of Panang curry. Where classic European mussel dishes use white wine, butter or cream, this Thai version uses creamy coconut milk and an aromatic paste for something altogether more exciting.
Samphire, a coastal sea vegetable with a salty, crunchy bite, adds texture and a pop of green. It isnโt traditional in Thai cooking, but its saltiness complements the fish sauce and Panang paste so well it feels like it belongs.
What is Panang Curry?
Panang (also spelled phanaeng or penang) is one of Thailandโs richest and most approachable curries. Its name is sometimes linked to the Malaysian island of Penang, though its exact origins are debated. Itโs thicker than most Thai curries and milder than red, with a warm, rounded spice.
Our Thai Panang Curry Paste, a UK Great Taste Award winner, is stone-ground from red chilli, lemongrass, galangal, kaffir lime rind, coriander root, garlic and shallots, with warm spices: coriander seeds, cumin, nutmeg and white pepper.
How to Buy, Store and Clean Mussels
Freshness is everything with mussels.
Buying: choose mussels with shiny, damp, tightly closed shells that smell clean, like the sea. If one is slightly open, give it a firm tap. If it closes, itโs alive. Avoid any with cracked or broken shells.
Storing: keep them in an open bowl in the fridge, covered with a damp cloth, and cook them within 24 hours. Never store them in a sealed bag or in fresh water.
How to clean mussels:
Rinse them under cold running water.
Scrape off any barnacles with the back of a knife.
Pull off the โbeardโ (the stringy threads poking out of the shell) by tugging it firmly towards the hinge.
Tap any open mussels. Discard any that donโt close, or that have cracked shells.
Fresh or frozen? Fresh mussels give the best texture and flavour. Frozen mussels are softer and less sweet, so fresh is best when mussels are the star.
Key Ingredients
Mae Jum Thai Panang Curry Paste: the foundation, bringing chilli, galangal, lemongrass, kaffir lime and warm spices in one spoonful.
Full-fat coconut milk: the creamy body of the sauce, softening the chilli and rounding out the spices.
Samphire: salty and crunchy. If you canโt find it, use seaweed, though the flavour will change slightly.
Fish sauce and palm sugar: salt and gentle caramel sweetness to balance the sauce. Soft brown sugar works instead of palm sugar.
Kaffir lime leaves: torn or finely chopped at the end for a bright, citrusy fragrance.
Red chilli: sliced, for colour and a little extra heat.
How to Make Mussels in Panang Sauce
The full recipe is in the recipe card below. Hereโs how it comes together:
Fry the paste. Fry the Panang paste in a little coconut oil over medium heat for 2 minutes, stirring, until fragrant.
Make the sauce. Add the coconut milk, fish sauce and palm sugar and bring to a simmer.
Steam the mussels. Add the cleaned mussels and samphire, cover with a lid and cook for 4โ5 minutes, until the shells open. Donโt stir too much.
Finish. Discard any mussels that stay closed, then add the kaffir lime leaves and red chilli. Serve immediately.
Tips for the Best Result
Donโt overcrowd the pan. Use your biggest wok or pan so all the mussels cook evenly.
Lid on, hands off. Let the steam do the work. Too much stirring breaks the shells and toughens the meat.
Serve straight away. Mussels are best the moment they come off the heat. Warm your bowls and have your bread or fries ready before you start.
Bread isnโt optional. Crusty sourdough, baguette or flatbread is essential for mopping up the sauce.
Serving Ideas
Thai-style moules frites: serve with thin, crispy fries for dipping.
With jasmine rice: spoon the mussels and sauce over rice for a heartier meal.
Try another paste: swap Panang for green curry paste, as in our Thai Green Curry Mussels, or try red or yellow.

From Jumโs Kitchen
Mussels are one of the best-value treats from the sea, and theyโre at their plumpest in the colder months, which makes this a perfect dish for autumn and winter evenings. They cook in minutes, and as they steam open, their sweet, briny juices mix into the Panang sauce, making it even richer.
Our Panang Curry Paste brings the warmth: gentle chilli, fragrant lemongrass and kaffir lime, and the rounded spice of cumin and nutmeg, all stone-ground in Southern Thailand from our family recipe. Add a handful of samphire for a salty crunch, and serve with plenty of crusty bread or a bowl of chips. Itโs a Thai twist on a classic thatโs every bit as good for a quick weeknight supper as it is for friends around the table.
