Tips for success

Chill the glasses and the blender jar for 10 minutes before you start. Cold glasses keep the lassi thick and the layers crisp, and a cold jar helps the blended mixture stay smooth while you pour. This simple step makes a visible difference to the final texture and gives the drink a more refreshing feel from the first sip to the last.

Taste the lassi before you pour it. Ripe bananas and fresh blueberries vary in sweetness, so you may want a little more honey or a tiny extra pinch of cardamom. Add the spice gradually, because ground cardamom is strong and a small amount goes a long way. Blend again for a few seconds after each adjustment so the flavour is evenly distributed.

Variations

Mango version: Replace the blueberries with the same amount of diced ripe mango for a golden, tropical lassi. Keep the banana, cashews, yogurt, honey and cardamom, and blend as directed. The cardamom pairs especially well with mango, and the sauce layer can be made with a spoonful of mango instead of blueberries for a matching finish.
Chocolate-free crown: Leave out the grated white chocolate and finish each glass with only the whipped cream and a few fresh blueberries. This gives a lighter look and a cleaner fruit flavour, with the cardamom and cashew notes more prominent. It suits readers who want the same dramatic presentation with a simpler topping.
Thicker spoon lassi: Use Greek yogurt in place of the plain yogurt and reduce the milk or liquid to a minimum. The result is a much thicker, spoonable lassi that holds the whipped cream even more firmly. Serve it in small bowls with the sauce and the chocolate curls for a dessert-style finish that feels rich and substantial.
Nutty almond twist: Swap the raw cashews for blanched almonds, chopped finely, for a slightly different nutty flavour. Almonds are a tree nut, so keep this in mind for allergy-sensitive guests. Blend in the same order and use the same amounts, then finish with the sauce, chocolate and cream as directed for a fresh take on the classic.

Storage and make-ahead

Fridge: Keep leftover lassi in an airtight container in the refrigerator for up to 24 hours. Stir before serving, as it may separate slightly.

This lassi is best served the moment it is made, while it is cold, thick and vividly coloured. If you need to keep it for a short time, pour the blended lassi into an airtight container, press a sheet of plastic wrap onto the surface and refrigerate it.

Keep the blueberry sauce, the grated white chocolate and the whipped cream separate, since they will lose their texture if they sit in the drink. Use the lassi within a day for the freshest flavour, and stir it briefly before serving because it can separate slightly as it rests.

You can prepare the parts of this drink in advance to speed up serving. Slice the banana, chop the cashews and grate the white chocolate up to a few hours ahead, storing each in a separate covered container in the refrigerator. Keep the blueberries washed and dry in a sealed container.

Blend the lassi shortly before serving, because the banana can darken and the mixture thickens as it stands. Whip the cream and fill the piping bag just before you assemble the glasses so the crown stays tall and fluffy. Working this way keeps every component at its best while making the final assembly quick.

Serving ideas

Serve the lassi in tall, clear glasses so the dark blueberry sauce, the white chocolate curls and the purple body show clearly from the side. Pour the lassi slowly down the inside of each glass to keep the layers distinct, then pipe the whipped cream into a tall crown on top.

Add a few extra white chocolate curls and a fresh blueberry or two for a finished look. Provide a straw or a long spoon so guests can reach the cream and the sauce at the bottom with every sip.

This lassi suits many occasions. It works well at brunch alongside a light breakfast, as a cool afternoon drink, or as a dessert served in a tall glass after a simple dinner.

Because it is sweet and creamy, it pairs nicely with spiced or savoury dishes, which balance its richness. Serve it cold, straight after blending, to enjoy the smooth texture and the vivid colour at their best.

Frequently asked questions

Can this lassi be made without a high-speed blender?

A standard blender can work, but it needs more time. Blend the cashews and banana first on high speed until they break down, then add the blueberries, yogurt, honey and cardamom. Blend for a full minute or longer, scraping the sides as needed, until the mixture is completely smooth and an even purple-pink. Any gritty texture means the cashews need more blending time.

Which yogurt gives the best texture for this lassi?

Plain whole-milk yogurt gives a rich, creamy lassi with a gentle tang. Plain Greek yogurt produces an even thicker drink that holds the whipped cream well. If the Greek yogurt feels too stiff to blend, add a splash of cold milk and blend again until smooth. Avoid flavoured or sweetened yogurts, since they change the balance of the honey and cardamom.

Can the whipped cream be replaced with something else?

Yes. A ready-made whipped topping, kept chilled, can be piped in the same way and gives a similar tall crown. For a lighter finish, you can also skip the cream and add a few extra blueberries and grated white chocolate on top. The drink tastes just as good without the crown, though the presentation is less dramatic.

Why does the blueberry sauce sink to the bottom of the glass?

The sauce is made from crushed blueberries with honey, which is denser than the blended lassi. Spoon it into the bottom of the glass before pouring, then pour the lassi slowly down the side. This keeps the dark layer at the base, where it creates a clear swirl of colour that you see through the glass as you drink.

How do you keep the whipped cream crown tall in the glass?

Whip the heavy cream to soft peaks and keep it chilled until you pipe it. Pipe it onto the glass just before serving, squeezing the bag from the bottom and lifting slowly to form a tall swirl. Warm cream slumps quickly, so refrigerate the piping bag between uses and assemble each glass one at a time for the neatest result.

Blueberry Cardamom Creamy Cashew Lassi Smoothie with Whipped Cream

Prep 15 minCook 2 minTotal 17 minServes 2

Tall glass of purple blueberry cardamom lassi topped with whipped cream and white chocolate curls

Ingredients

1 cup fresh blueberries, plus a few extra for the sauce
1 ripe banana, sliced
1/3 cup raw cashews, chopped
1 cup plain whole-milk yogurt
2 tbsp honey, plus a drizzle for the sauce
1/4 tsp ground cardamom, a pinch to taste
1 oz white chocolate, for grating
1/2 cup heavy cream, whipped to soft peaks

Instructions

Put on clean gloves if you like, then slice the banana on a wooden cutting board. Chop the cashews finely and set them beside a bowl of fresh blueberries. Keep the prepared ingredients close together so they go into the blender in order.
Hold a block of white chocolate against the fine side of a box grater and grate it over a sheet of parchment or the cutting board. Let the fine white curls collect in a small pile. Set them aside in the refrigerator until serving.
Add the blueberries, sliced banana, chopped cashews, yogurt, a drizzle of honey and a pinch of ground cardamom to the glass blender jar, in that order. Secure the lid firmly before blending.
Blend on high speed until the mixture is completely smooth and a vivid purple-pink. Stop the blender and scrape down the sides once if needed, then blend briefly again. Taste and add a little more honey or cardamom if you want it sweeter or more aromatic.
Spoon a few fresh blueberries with a drizzle of honey into the bottom of each clear glass and crush them lightly into a dark sauce. Sprinkle a layer of grated white chocolate over the sauce. Pour the blended lassi slowly over the top.
Fill a piping bag fitted with a star tip with the whipped cream. Squeeze a tall swirl over the top of each glass so it forms a thick, fluffy crown above the purple lassi. Finish with a few more white chocolate curls and serve immediately.
