Standing in front of a Thai menu for the first time and choosing between green curry, red curry, and Massaman is one of those decisions that feels harder than it should be. All three are curries. All three are Thai. But beyond that, they are genuinely different dishes — different flavour profiles, different heat levels, different occasions.
This guide explains exactly what makes each one distinct, so you can order the right curry for your taste the first time rather than working it out by trial and error.
Quick Reference — The Three Curries at a Glance
Green Curry — Gaeng Keow Wan
Heat level: Medium to hot — the most consistently spiced of the three
Colour & base: Green chilli paste, coconut milk, Thai basil, kaffir lime leaves
Best for: Adventurous first-timers who enjoy heat; fans of bright, fresh, herbal flavour
Red Curry — Gaeng Phed
Heat level: Medium — slightly milder than green, more savoury depth
Colour & base: Dried red chilli paste, coconut milk, fish sauce, palm sugar
Best for: Those who want a versatile, crowd-pleasing curry with warmth rather than punch
Massaman Curry — Gaeng Massaman
Heat level: Mild — the gentlest of the three with almost no sharp heat
Colour & base: Influenced by Persian and Indian spicing — cinnamon, cardamom, star anise, peanuts, potato
Best for: Beginners, those sensitive to heat, anyone who enjoys rich, sweet-savoury depth
Green Curry — Bold, Fresh, and Aromatic
Green curry gets its colour from fresh green chillies blended into the paste — and those chillies also determine its heat level. It is generally the hottest of the three, though the intensity varies depending on how much paste is used and whether the recipe leans into the heat or tempers it with coconut milk.
The flavour profile is bright and herbal — lemongrass, kaffir lime, Thai basil, and galangal all feature prominently. The coconut milk adds richness but does not dominate; green curry tends to feel lighter and more vibrant than the other two. It works well with chicken, fish, tofu, or vegetables, and the heat is immediate rather than lingering.
If you enjoy a curry with genuine heat and a fresh, aromatic quality, green is the one to order. If you are unsure about heat, it is worth discussing with the kitchen before committing — the same paste can produce very different results depending on how it is made.
Red Curry — The Versatile Middle Ground
Red curry sits between green and Massaman in almost every respect — heat, richness, and complexity. It is built on dried red chillies rather than fresh ones, which gives it a warmer, slightly smoky flavour compared to the sharper heat of green curry. The coconut milk base is rich and full, and the finished dish tends to have a satisfying savoury depth that makes it one of the most widely ordered curries in Thai cuisine.
Red curry works with a wider range of proteins and vegetables than green, and its flavour is more forgiving — it is harder to get wrong and easier to enjoy across a range of spice tolerances. For first-timers who want something genuinely Thai but are not ready to commit to green curry’s heat level, red is a reliable and rewarding choice.
Massaman — Rich, Mild, and Unlike Any Other Thai Curry
Massaman is the outlier. It arrived in Thailand via Persian and Malay traders centuries ago, and the influence shows clearly in its spice profile — cinnamon, cardamom, star anise, and cloves give it a warmth that is closer to a slow-cooked Indian curry than anything else on a Thai menu. Peanuts and potato are almost always present, and the sauce is thick, rich, and deeply sweet-savoury.
In terms of heat, Massaman is the mildest of the three by a significant margin. There is almost no sharp chilli heat — the warmth comes from the whole spices rather than fresh or dried chilli. For anyone new to Thai food, unsure about heat, or simply looking for something different from the standard Thai curry experience, Massaman is the most accessible and often the most surprising choice on the menu.
Which Curry to Order at Mangosteen Bristol
Mangosteen serves all three curries as part of its Thai tapas menu across three Bristol locations. Because the format is sharing plates rather than individual portions, ordering a curry at Mangosteen does not mean committing the whole meal to one choice — you can order a Massaman alongside a green curry and try both, which is arguably the best way to understand the difference between them. You can see the full current menu at mangosteenbristol.info/menu before you visit.
Mangosteen has three locations across Bristol — Cotham Hill, North Street in Bedminster, and Gloucester Road in Bishopston. All three serve the same core menu, with curries available for dine-in and delivery.
Frequently Asked Questions
Which Thai curry is the mildest?
Massaman is consistently the mildest Thai curry. Its heat comes from whole spices like cinnamon and cardamom rather than chilli, and the finished dish has very little sharp heat. It is the most accessible option for anyone new to Thai food or sensitive to spice.
Which Thai curry is the hottest?
Green curry is generally the hottest of the three, as it is made from fresh green chillies which retain more volatile heat compounds than dried chillies. The heat level can vary significantly between kitchens, so it is always worth asking if you are unsure.
What is the difference between green and red curry paste?
Green curry paste is made from fresh green chillies, lemongrass, galangal, kaffir lime zest, and Thai basil — giving it a bright, herbaceous, fresh flavour. Red curry paste uses dried red chillies, which produce a deeper, slightly smoky warmth and a richer, more savoury base. The coconut milk used in both sauces is the same — it is the paste that creates the fundamental difference in flavour and colour.
Can I order more than one curry at Mangosteen?
Yes — and it is one of the best things about the Thai tapas format. Rather than committing to a single curry, you can order two or three dishes and share them across the table. This is actually the most natural way to experience Thai food, which has always been a communal dining tradition. Book a table at Mangosteen Bristol and order one of each to settle the debate for yourself.
Is Massaman curry authentic Thai food?
Yes — Massaman has been part of Thai cuisine for centuries, though its origins reflect the Persian and Malay trading routes that passed through Thailand historically. Its spice profile is distinct from other Thai curries precisely because of those influences, but it is firmly embedded in Thai culinary tradition and appears on menus across Thailand from street food stalls to fine dining restaurants.
Ready to Try All Three?
The only reliable way to settle the green versus red versus Massaman debate is to order all three and share them at the table. At Mangosteen, the Thai tapas format makes that straightforward — no negotiating over a single main course, just a table full of dishes and the freedom to try everything.
