Chef Noor's Tip

Let both the cake and the blueberry sauce cool completely before assembling, or the cream will soften and slide.

Ingredient Swaps

The blueberries can be replaced with strawberries or mixed berries depending on availability, keeping the same cooking method. For a lighter cream, use a low-fat whipping cream or fold in a little yogurt. The starch can be swapped for cornflour to thicken the berry sauce.

Common Questions

Why is starch added to the blueberry sauce?

The starch thickens the sauce so it holds together and does not run between the cake layers.

How do I get stable whipped cream?

Whip the cold cream until firm peaks form, and avoid over-whipping so it does not turn grainy.

Should the cake cool before filling?

Yes, a cold cake holds together better and keeps the cream from melting when filling.

What does the lemon zest do?

The zest adds a fragrant citrus note that boosts the cake's lemon flavour and balances the sweetness of the berries.

Can it be made ahead of serving?

Yes, keep it refrigerated until serving so the layers stay firm and the cream stays cold.
