Thai Curry Paste: How to Choose the Right Flavour, Size and Ingredients

Thai curry paste can turn a few everyday ingredients into a fragrant meal, but choosing the right jar or sachet is not always straightforward. UK shoppers are often faced with different spice levels, unfamiliar ingredients, varying pack sizes and broad claims such as “authentic” or “traditional”.

The main purchasing mistakes are usually easy to avoid:

• Choosing by colour alone: Green curry is not automatically milder than red curry. Heat depends on the chilli blend and the quantity used.
• Ignoring allergens: Many Thai curry pastes contain shrimp paste, while others include soy, milk, sesame, wheat or coconut.
• Buying too large a pack: A 400g jar may suit regular curry cooking, but a smaller sachet can be more practical if you cook Thai dishes occasionally.
• Treating paste as a complete meal: Most products require coconut milk, oil, vegetables and a protein such as chicken, tofu, beef or seafood.

What to Check Before Buying Thai Curry Paste

1. Flavour profile and intended dish

Choose the paste according to the meal you plan to cook.

• Thai red curry paste: Usually has a chilli-forward, aromatic profile with lemongrass, garlic, galangal and lime peel. It works well with chicken, prawns, tofu and vegetables.
• Thai green curry paste: Often contains green chilli, lemongrass, basil or lime-related ingredients. It suits chicken, seafood and vegetable curries served with coconut milk.
• Massaman curry paste: Typically includes warmer spices such as cardamom, cinnamon or clove, alongside Thai aromatics. It pairs well with beef or chicken, potatoes and peanuts.
• Panang curry paste: Usually creates a thicker, richer curry and can be used with coconut milk, meat or vegetables.
• Yellow curry paste: Turmeric, cumin and coriander contribute to its golden colour and warm flavour. It is commonly used with chicken and potatoes.

Thai curry paste is not interchangeable with Indian curry paste, Malaysian rendang paste or a Madras spice paste. These products use different aromatics and cooking methods. For example, Malaysian rendang paste is designed for a thicker, slower-cooked dish, while an Indian jalfrezi or butter chicken paste may be used with tomatoes, yoghurt or dairy.

2. Allergen information and dietary suitability

Always read the current packaging before purchase, particularly if you are cooking for guests. Several products in this category contain shrimp or other crustaceans, including a number of red, green, yellow and Massaman pastes.

Other ingredients to check include:

• Soy, which appears in some Thai and Indian-style pastes
• Milk, found in products such as butter chicken paste
• Wheat, which may be present in some Panang pastes
• Sesame, peanuts and tree nuts
• Coconut, which may be included directly rather than added separately

Some products are labelled vegan or gluten-free, but “may contain” statements can still be important for allergy-conscious households. Do not assume a vegetable curry paste is vegetarian: shrimp paste or fish-derived ingredients may still be included.

3. Pack size, storage and preparation

A small 50g sachet or jar can be suitable for one or two cooking occasions and reduces the risk of keeping an opened product for too long. Larger 200g and 400g jars offer better convenience for regular home cooks, batch cooking and meal preparation.

Check whether the product is intended for cooking only. Concentrated paste can be high in salt and chilli, so it should generally be fried or simmered with other ingredients rather than eaten directly. After opening, most products need refrigeration in a tightly sealed container. Use the storage period printed on the pack: recommendations vary from a few days to several months.

For a simple curry, fry the paste briefly in oil, add coconut milk or water, then add vegetables and your chosen protein. Cook until the dish is piping hot throughout; poultry should be thoroughly cooked before serving.

Frequently Asked Questions

What should I add to Thai curry paste?

Most Thai curry pastes work with coconut milk, vegetables and a protein such as chicken, beef, seafood or tofu. Frying the paste briefly in oil first helps release its aroma. Follow the specific instructions on the packaging, as quantities and cooking times vary.

Is Thai curry paste suitable for vegetarians?

Not necessarily. Red, green, yellow and Massaman pastes may contain shrimp paste or fish-related ingredients. Check the allergen declaration and ingredient list for every product. A product labelled vegan or vegetarian is generally the more appropriate choice, but packaging should still be checked before use.

How long does Thai curry paste last after opening?

Storage life varies considerably. Some products recommend using the paste within a few days, while others allow several weeks or months. Refrigerate opened paste in a sealed container and follow the manufacturer’s stated timeframe. Discard it if the packaging is swollen or the paste develops an unusual smell, colour or texture.
