How to Make Som Tum Thai at Home

Som Tum Thai is fresh, crunchy and packed with sweet, sour, salty and spicy flavour. Making the dressing from scratch normally means balancing palm sugar, tamarind, fish sauce, citrus, chilli and garlic—but we have already done that part for you.

At its simplest, all you need is fresh green papaya and Muay’s Som Tum Thai Sauce. Shred the papaya, add the sauce and toss everything together. You can then add tomatoes, long beans, peanuts or dried shrimp when you want the fuller version.

Also written as Som Tam, this famous green papaya salad is quick to prepare once the papaya is shredded. Here is how to make it at home with no complicated dressing measurements required.

What is Som Tum Thai?

Som Tum is a Thai green papaya salad made by lightly pounding and tossing crisp shredded papaya with a strongly flavoured dressing. The name refers to the traditional preparation: som describes the sour flavour, while tum means to pound.

There are several styles of papaya salad. Som Tum Thai has a sweet, sour, salty and spicy dressing and is commonly served with tomatoes, long beans, peanuts and sometimes dried shrimp. It is different from Som Tum Pu Plara, which gets its bolder fermented flavour from salted crab and fermented fish sauce.

This recipe is for Som Tum Thai using our homemade family-recipe sauce.

The two essentials

For the simplest version, you only need:

• Around 300g shredded green papaya
• Muay’s Som Tum Thai Sauce, added to taste

That is enough to make approximately two generous side portions. The papaya provides the fresh crunch, while the sauce brings together the sweetness, acidity, saltiness, chilli and garlic.

Optional additions

To make a fuller Som Tum Thai, you can also add:

• 2 Thai yard-long beans, cut into short pieces
• 4 cherry tomatoes, halved
• A small handful of roasted peanuts
• 1 tablespoon dried shrimp, optional
• Extra fresh chilli if you prefer more heat

These additions are optional. You can keep it as simple as papaya and sauce or build it up depending on what you have at home.

How to prepare green papaya

Green papaya is the firm, unripe version of the fruit. Unlike ripe orange papaya, its flesh is pale, crisp and mild, making it ideal for absorbing the dressing without becoming overly sweet or soft.

1. Peel the green papaya.
2. Cut it lengthways and remove the seeds from the centre.
3. Shred the flesh into long, thin strands using a julienne peeler, mandoline or papaya shredder.
4. Keep the shredded papaya cold and dry until you are ready to dress it.

Shredding the papaya shortly before serving will give you the best texture. If you prepare it in advance, keep it chilled separately from the sauce.

How to make Som Tum Thai with Muay’s sauce

Using a mortar and pestle

1. If using long beans, tomatoes or extra chilli, place them in a large clay mortar first.
2. Gently pound them a few times to bruise the vegetables and release their juices. They should still keep some shape.
3. Add the shredded green papaya and a little Muay’s Som Tum Thai Sauce.
4. Use a spoon and pestle together to lift, lightly pound and toss the papaya. Add more sauce gradually until everything is evenly coated and seasoned to your taste.
5. Fold through the peanuts and dried shrimp, if using, and serve immediately.

The aim is to bruise and mix the ingredients—not crush the papaya into a paste. The finished salad should still feel crisp and fresh.

Without a mortar and pestle

You can still make Som Tum at home without special equipment:

1. Put the long beans, tomatoes and any extra chilli into a sturdy mixing bowl.
2. Lightly bruise them using the end of a wooden rolling pin or another suitable blunt utensil.
3. Add the shredded papaya and sauce.
4. Toss everything thoroughly with two spoons until the papaya is evenly coated.
5. Finish with peanuts or dried shrimp and serve straight away.

You will not get quite the same pounded texture, but the fresh crunch and balanced flavour will still be there.

What is in Muay’s Som Tum Thai Sauce?

Our Som Tum Thai Sauce is freshly prepared in the UK by our aunt Muay using our family recipe. It contains:

• Palm sugar
• Tamarind juice
• Fish sauce
• Lemon juice
• Chilli
• Garlic
• MSG

These ingredients create the sweet, sour, salty and spicy balance associated with Som Tum Thai, without having to measure and adjust the dressing each time.

The sauce is homemade, available exclusively from Muay Supermarket and supplied in a 250ml refrigerated bottle.

How to customise your Som Tum

One of the best things about Som Tum is how easily you can adjust it to your taste.

For more heat

The sauce already contains chilli, but you can bruise one or two fresh Thai chillies with the vegetables before adding the papaya.

For more crunch

Add extra long beans, roasted peanuts or a little more freshly shredded papaya.

For more savoury flavour

Add dried shrimp or serve the salad alongside grilled chicken, sticky rice or other Thai dishes.

For a lighter version

Keep it simple with green papaya, sauce and tomatoes. You do not need to add every traditional topping for the salad to be enjoyable.

Common Som Tum mistakes to avoid

Using ripe papaya

Ripe papaya is orange, soft and sweet. For Som Tum, you need firm green papaya that can be shredded and remain crisp after dressing.

Pounding too hard

The papaya should be lightly bruised, not mashed. Pound gently while using a spoon to lift and turn the strands.

Adding too much sauce at once

Start with a smaller amount, toss thoroughly and taste before adding more. It is easier to increase the seasoning than to remove it.

Dressing the papaya too early

Som Tum is best served shortly after mixing. Leaving the papaya in the dressing for too long will gradually soften its texture.

Frequently asked questions

Do I need a mortar and pestle to make Som Tum?

No. A mortar and pestle gives the salad its traditional lightly pounded texture, but a sturdy bowl and a suitable blunt utensil will work at home. The important part is to bruise the vegetables gently and coat the papaya evenly.

Can I use ripe papaya?

Ripe papaya is too soft and sweet for this salad. Choose firm, unripe green papaya for the crisp texture associated with Som Tum.

How spicy is Muay’s Som Tum Thai Sauce?

The sauce already contains chilli and has a spicy flavour. Everyone’s tolerance is different, so add the sauce gradually and taste as you go. Fresh chilli can be added separately if you want more heat.

Is the sauce vegetarian or vegan?

No. Muay’s Som Tum Thai Sauce contains fish sauce, so it is not suitable for vegetarians or vegans. Adding dried shrimp also introduces crustaceans, while peanuts are another common allergen.

Can I prepare Som Tum in advance?

You can peel and shred the papaya in advance, but keep it chilled and separate from the dressing. Mix the salad shortly before serving so the papaya stays crisp.

What can I serve with Som Tum Thai?

Som Tum is often enjoyed with sticky rice and grilled meat, but it also works as a fresh side dish alongside other curries, stir-fries or barbecue food.

How should I store the sauce?

Keep Muay’s Som Tum Thai Sauce refrigerated and use it by the expiry date shown on the back of the bottle.

Make Som Tum Thai at home

You do not need to measure several different dressing ingredients every time you want fresh papaya salad. Start with two essentials:

• Fresh Green Papaya – Malakor
• Muay’s Som Tum Thai Sauce

Then add Thai yard-long beans, tomatoes, peanuts or dried shrimp to make it your own.
