Step-by-Step Guide to Making Mary Berry’s No-Bake Lemon Tart

Step 1: Prepare the Biscuit Base

Crush the digestives into fine crumbs and mix with melted butter. Press the mixture firmly into the tart tin, smoothing it across the base and sides.

Step 2: Chill the Base

Place the tart base in the fridge for at least 20–30 minutes to firm up.

Step 3: Make the Lemon Filling

In a large bowl, whisk the condensed milk, cream, lemon zest, lemon juice, and vanilla until thick and smooth.

Step 4: Pour the Filling into the Base

Spread the filling evenly over the chilled biscuit crust. Smooth the top with a spatula.

Step 5: Allow to Set

Chill the tart for at least 4 hours, or preferably overnight, until completely set.

Step 6: Decorate and Serve

Garnish with lemon zest, whipped cream, or thin lemon slices. Slice and enjoy chilled.

FAQs

Why is my no-bake lemon tart not setting properly?

The tart usually fails to set when there isn’t enough acidity or the cream is under-whipped. Use fresh lemon juice, not bottled, and whisk the filling until it thickens before pouring it into the base. Allow at least 4 hours of chilling or overnight for the best firmness.

How do I stop the biscuit crust from crumbling when slicing?

A crumbly crust means the biscuits weren’t pressed firmly enough or the butter ratio was too low. Press the mixture tightly into the tin using the back of a spoon and chill for at least 20–30 minutes. Adding an extra 10–15g of melted butter helps bind it better.

Can I make Mary Berry’s no-bake lemon tart ahead of time?

Yes, this dessert is ideal for advance preparation. You can make it 24 hours ahead, keep it covered in the fridge, and let it chill overnight so it sets fully and the flavours develop beautifully.

Why does my lemon filling taste too sweet?

The sweetness comes from condensed milk, so balancing it with extra lemon zest or an additional tablespoon of lemon juice helps sharpen the flavour. Using tart lemons or adding a pinch of salt also reduces perceived sweetness.
