As an island, the United Kingdom benefits from a wealth of great seafood and I love it all!
Crab season runs from March to October, however, in the summer months the crabs are breeding are growing new shells, so availability drops.
It's not always possible to buy fresh crab locally, but it's widely available online, fresh or frozen, so you can enjoy it all year round.
I like to serve this as a starter to a special meal, such as Christmas or an anniversary, because it's packed with flavour, but is ridiculously easy to make. This means you can make it in advance to save time too.
There are lots of variations to this dish, from the crab to the salad vegetables, so you can use other ingredients that you prefer.
Of course, I've added a little spice with some sriracha sauce, but there are alternatives and the crab salad is equally good without it too, so leave it out if you wish.

🥘 Ingredients
- Crab - fresh or frozen crab meat. For flavour and texture, it's best to use a mixture of the white claw meat and the rich brown meat.
- Avocado - fresh ripe avocado. I usually buy the ready to eat ones.
- Lemon juice - fresh or from a bottle for flavour and to keep the avocado from turning brown.
- Radishes - for garnish and their peppery crunch.
- Cucumber - English cucumber to garnish the plate.
- Mayonnaise - plain mayonnaise, full fat or reduced. This will bind all of the ingredients together.
- Onion - red onion for colour, crunch and sweetness.
- Capers - these salty little berries are often used in sauces or served with fish. Drain on some kitchen towel to remove excess moisture.
- Salt - flaked sea salt for flavour as there is no cooking involved.
- Pepper - freshly ground black pepper.
- Spice - this is such a personal preference. I used sriracha sauce which does vary from brand to brand or you could use Tabasco. The main thing to remember is to add it to taste.
💭 Top Tip
- Avocados need to be ripe, but not mushy for chopping. As a guide, the darker the colour of the skin, the more ripe the avocado. To make sure, give the flesh a gentle squeeze and it should give a little.
- If you find that your avocados are either hard as bullets or too mushy, it's also possible to buy frozen avocado pieces, which are great for salads.
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post.
🍽 Equipment
- sharp knife
- chopping board
- mixing bowl
- 4 presentation rings - optional
🔪 Instructions
Peel and chop the onion finely.
Cut the cucumber and radish into fine slices.
You could also used a mandolin or fool processor to slice the cucumber if you prefer.
Chop the avocado into rough cubes.
Toss the cubes with the lemon juice.
💭 Top Tip
- Slice around the stone lengthways. I prefer to use a serrated vegetable knife for this for safety.
- Twist the avocado and it should open into 2 halves.
- Carefully remove the stone with a teaspoon.
- Use the knife to slice the avocado into cubes while in the skin.
- Peel off skin carefully or use a blunt knife or spoon to scoop out the cubed flesh.
- If you have a leftover avocado half cover the cut side in lemon juice and wrap in cling film. Store in the fridge for up to 2 days.
Put the crab, avocado, onion, capers, salt and pepper into a large mixing bowl.
If you are using sriracha or other spice, mix it together with the mayonnaise before adding to the bowl.
This will make sure that the spice is mixed in evenly.
Stir the mixture gently to combine.
The idea is to not overmix so that the avocado retains its shape and the crab texture is still defined.
Arrange the cucumber slices on a side plate, slightly overlapping.
Use a presentation ring and place in the centre of the cucumber.
Divide the mixture between the rings and press down gently.
💭 Top Tip
- If you don't have presentation rings, line 4 ramekins or small bowls with clig film and fill with the spicy crab salad. Regrigerate and then turn onto the plates just before serving.
Chill until you are ready to serve then garnish with radish slices to serve.
2 hours chilling is ideal if you are serving the salad like this, otherwise you can serve straight away.

📖 Variations
Crab
- Spicy kani salad - kani is a Japanese phrase for imitation crab meat, which is also known as surimi. It is usually sold as crab sticks.
- Spicy seafood salad - use a mixture of fish such as prawns (shrimp), crab and surimi.
- Tuna - make this salad using canned tuna for a more economical option.
- Salmon - use canned, poaced or foil baked salmon as an alternative.
Salad ingredients
These alternatives work well.
- Cucumber - cut into small cubes.
- Radish - cut into small cubes or slices cut in half.
- Celery - slice thinly.
- Tomato - remove the seeds and dice. The seeds and surrounding flesh are too juicy and will change the texture of the salad.
- Spring onions - slice thinly
- Herbs - use a tablespoon or chopped fresh parsly, basil or dill.
- Hard boiled egg - chopped.
Spice
If you don't have Sriracha try these ideas. The measurements are only a guide. I would suggest adding a small amount and adjust the amount to taste.
- Tabasco - few drops
- Cayenne pepper - quarter to half a teaspoon.
- Chilli powder - quarter to half a teaspoon.
- Shichimi - this is a Japanese spice blend also known as nana-iro tgarashi. It's a mix of seven spices including chilli powder, sesame seeds, hemp and ginger. Use sparingly!
- Paprika - use half to one teaspoon.
Garnishes
Decorate with:
- Capers
- Sprig of dill
- Small dice of cucumber
- King prawns
- Teaspoon of lumpfish roe
🍣 Storage
- Refrigerator - cover and store in the refrigerator for up to 2 days.
- Freezer - not suitable for freezing.
🍱 Prepare in Advance
- Make the salad the day before and leave in the fridge until you are ready to serve.
🤔 FAQs
Imitation crab is also known as surimi. It is used extensively in Japanse cooking and sushi dishes. Surimi means pounded meat.
It consists of cheaper white fish pressed into sticks and can be easily shredded into strands with your fingers.
It tends to be low in calories and fat, however, there are added sugars, salt, thickeners, colourings and flavourings to make it look more like crab.
Although edible crabs are found all over the UK the town of Cromer on the north Norfolk coast is famous.
Cromer crabs are caught in the North Sea and due to the waters, which are full of nutrients, the crabs are sweet and more tasty than other area.
I have visited several times and there are many stallholders selling dressed crab and small eateries offering amazing crab sandwiches.
If you don't want to use presentation rings you can just serve the salad on a plate or in a lettuce leaf.
It's also great in a sandwich or wrap.
Use the crab to fill vol au vents or serve on small pieces of toast as a canapé.
