This is the canapé you make when you've decided to host drinks at the last minute and you've got a tin of caviar in the fridge. Five minutes of work, three ingredients, and a result that beats anything you'd buy from M&S.
The cucumber serves three purposes. It's a structural base (firm enough to hold the cream and caviar). It's a palate cleanser (cool, watery, mildly grassy). And it's a calorie-light vehicle (guests who don't want bread can still eat caviar). Three jobs done by one ingredient.
If you're hosting a party where multiple canapés are on the table, this is the one that goes first. Light, fresh, photogenic. It also works as the only canapé alongside drinks, with two or three rounds per guest.
Key Takeaways
- Use English cucumbers, not the smaller varieties, for proper rounds
- Cut 1cm thick, no thinner, the structure must hold
- Pat dry with kitchen paper before topping, otherwise cream slides off
- Crème fraîche must be full-fat, half-fat goes watery
- 2-3g of caviar per round is the right portion
The Ingredients
Makes 16 canapés
- 1 large English cucumber (around 350g)
- 100g full-fat crème fraîche
- 30-50g caviar (Oscietra recommended)
- 1 tsp finely sliced dill
- 1 tsp finely sliced chives
- A few flakes of Maldon sea salt
- Freshly cracked black pepper
The cucumber must be firm and crisp. A floppy cucumber gives floppy rounds. Buy the long, thin English variety, not the short knobbly ones. Press gently to test, it should feel solid all the way along.
For the crème fraîche, full-fat is essential. Half-fat goes watery on contact with cucumber moisture. Buy the French version where possible, the texture is denser.
The Method, Step by Step
Step 1: Slice the Cucumber
Wash and dry the cucumber. Trim both ends. Slice into 1cm-thick rounds, aiming for around 16 even slices.
If your cucumber is very seedy in the centre, scoop out a small hollow with the tip of a teaspoon (you want a slight depression to hold the cream and caviar without sliding off).
Step 2: Dry the Slices
Lay the cucumber rounds on kitchen paper. Press another sheet of kitchen paper firmly on top to absorb surface moisture. Wait 2 minutes, then remove the top paper.
This step matters. Wet cucumber surfaces cause the crème fraîche to slide off, taking the caviar with it. A properly dried surface holds the topping in place.
Step 3: Top with Crème Fraîche
Spoon a small dollop of crème fraîche onto the centre of each cucumber round. Around 1 teaspoon per round is the right portion.
Don't spread it flat. Leave it as a small mound. The cream needs height to support the caviar visually.
Step 4: Top with Caviar
Spoon caviar onto the crème fraîche, around 2-3g per canapé. The caviar sits on the cream, making contact with cucumber only via the cream layer.
Garnish with a few flakes of sea salt, a tiny scattering of dill or chives, and a light crack of black pepper at the edge of the plate. Serve within 30 minutes.
Tips for Getting It Right
Don't slice too thin. Cucumber rounds thinner than 1cm bend under the weight of cream and caviar, and the canapé becomes structurally unstable. 1-1.2cm is the sweet spot.
Pat dry properly. Skip the drying step and your canapés will look watery within 10 minutes. The cream slides, the caviar slides, the whole thing slumps.
Build close to serving time. Cucumber loses crispness once topped (the salt in the caviar starts pulling water out of the cucumber within 30 minutes). Build no earlier than 20 minutes before guests arrive.
Don't overload the cream. A teaspoon of crème fraîche per round is the right portion. Two teaspoons makes the canapé top-heavy and the cream slides off the cucumber.
Use a melon baller for the hollow. If you're scooping out the centre of seedy cucumber rounds, a small melon baller makes a clean shallow depression. A teaspoon works in a pinch but the result is uneven.
Variations and Pairings
With Beluga: Use 30g of Beluga across 16 rounds (around 2g per piece). Beluga's delicate flavour shines on the clean cucumber base. Skip the chives and use only a single tiny sprig of dill per round.
With salmon roe: Use 60g of salmon roe across 16 rounds. The bigger, brighter pearls give visual pop and the sweet-savoury flavour pairs beautifully with cool cucumber.
With smoked salmon ribbon: Add a small ribbon of cold-smoked salmon between the cream and the caviar. Adds depth and turns the canapé into a more substantial bite.
With dill cream: Mix the crème fraîche with 1 tsp of finely chopped dill and 1/2 tsp of lemon zest before topping. Slightly more flavour, ideal for parties where caviar is one of several offerings.
Wine pairing: Champagne, Sancerre, or chilled Picpoul. The cucumber pairs naturally with fresh herbal whites. Avoid heavy reds entirely.

Frequently Asked Questions
Can I make these canapés in advance?
Slice the cucumber, dry the rounds, and arrange on the serving plate up to 4 hours ahead, covered with cling film in the fridge. Top with crème fraîche and caviar within 20 minutes of serving. Pre-built canapés go watery within 30 minutes due to salt drawing moisture from the cucumber.
What's the right cucumber to use?
A large English cucumber (the long, smooth variety) is the proper choice. Mini cucumbers are too small. The Lebanese or Persian varieties are too thick-skinned. A properly fresh English cucumber is firm, dark green, and around 30cm long.
How many cucumber rounds per person?
At a cocktail party with multiple canapés, 2-3 rounds per person. As the only canapé alongside drinks, 4-5 rounds per person. Always make a few extra, cucumber and caviar canapés are addictive and guests come back.
Can I use sour cream instead of crème fraîche?
Yes but the texture is thinner. Sour cream slides off cucumber more easily than crème fraîche. If using sour cream, drain it through a coffee filter for 30 minutes to thicken slightly. Greek yogurt also works as a substitute, with a slightly sharper flavour.
