The tart was a hit, and I quickly learned that it wasn’t just the guests who loved it-I became a huge fan myself.
Mary Berry Lemon Posset Tart Recipe
Mary Berry’s Lemon Posset Tart is an elegant dessert that combines a creamy lemon posset (a British dessert made with cream, sugar, and lemon) with a buttery biscuit base. What makes this recipe stand out is the way the tart balances tangy and sweet flavors in a rich, velvety filling. The lemon posset sets beautifully, so you end up with a dessert that’s firm yet smooth, making it perfect for slicing.
The tart looks quite intricate, but trust me, it’s surprisingly easy to make. Here’s how Mary Berry suggests preparing this show-stopping dessert:
- Posset filling: The key to the tart is the silky posset filling, which requires just three ingredients: double cream, sugar, and lemon.
- Biscuit base: The base is a classic mix of crushed digestive biscuits (or graham crackers) and melted butter. Simple, yet delicious.
Ingredients Needed
Here’s a list of everything you’ll need for the tart. It’s nothing too complicated, and you likely have most of these items in your kitchen already:
For The Biscuit Base
- 200g digestive biscuits (or graham crackers)
- 100g melted butter
For The Posset Filling
- 600ml double cream (heavy cream will also work)
- 150g caster sugar (you could use regular granulated sugar)
- 2 lemons (you’ll need both zest and juice)
Equipment Needed
There are a few essential pieces of equipment to make this tart, but nothing you wouldn’t normally have in your kitchen. Here’s what you’ll need:
- Fluted tart tin (about 23cm in diameter)
- Food processor or a rolling pin (to crush the biscuits)
- Saucepan (for the posset filling)
- Whisk (to mix the posset)
- Citrus juicer (or just your hands, if you prefer squeezing lemons manually)
- Bowl (for mixing the crushed biscuits with butter)
- Spatula (for spreading the biscuit base)
How To Make Mary Berry Lemon Posset Tart?
Making this tart is straightforward, and each step is simple. Here’s how to do it:
-
Prepare The Biscuit Base
- Crush the digestive biscuits (either using a food processor or by placing them in a sealed bag and rolling a rolling pin over them). You want them to be fine crumbs.
- Melt the butter in a microwave or saucepan, then mix it with the biscuit crumbs until the mixture resembles wet sand.
- Press this mixture into the bottom of the tart tin, making sure it’s compact. You can use the back of a spoon to smooth it out evenly.
- Chill the base in the fridge for about 30 minutes, so it sets nicely.
-
Make The Posset Filling
- In a saucepan, combine the double cream and sugar. Heat over medium heat, stirring constantly until the sugar dissolves and the mixture just starts to simmer.
- Once simmering, remove the pan from the heat. Add the freshly squeezed lemon juice and zest. Stir to combine.
- Let the mixture cool for a few minutes, then pour it over the chilled biscuit base.
-
Set The Tart
- Place the tart back into the fridge and let it set for at least 3 hours, though overnight is best for the posset to firm up properly.
-
Serve
- Once the tart is set, you can slice it and serve it chilled. The posset should be smooth and firm, but still creamy and luscious.
Recipe Variations
While Mary Berry’s recipe is already delightful, there are a few ways you can tweak it depending on what you’re in the mood for or what you have on hand:
- Berry topping: Add fresh raspberries, strawberries, or blueberries on top of the tart for a fruity contrast to the creamy filling. You can also make a berry compote to drizzle over it.
- Herbal twist: If you want a more complex flavor, try infusing the cream with herbs like lavender or thyme before making the posset. Simply add the herbs to the cream as it heats up, let them infuse, then strain them out before mixing with the lemon.
- Ginger crust: Instead of digestive biscuits, try using ginger biscuits (cookies) for the base. The spicy ginger flavor pairs wonderfully with the zesty lemon.
- Chocolate variation: For a more indulgent twist, you could add a layer of chocolate ganache underneath the posset filling or mix some melted white chocolate into the cream for an extra-rich version.
What Goes Well With Mary Berry Lemon Posset Tart?
The tart is delicious on its own, but here are a few things that complement it beautifully:
- Whipped cream: A dollop of lightly whipped cream on the side balances the tartness of the lemon.
- Herbal tea: A cup of Earl Grey or chamomile tea makes for a lovely pairing with the tart’s citrusy freshness.
- Prosecco: If you’re in the mood for something celebratory, the lemon posset tart goes perfectly with a glass of chilled prosecco.
- Light salad: A simple green salad with a tangy dressing is a great way to balance out the richness of the tart, especially if you’re serving it as part of a larger meal.
What I Have Learnt
Over the years, I’ve made this tart many times, and there are a few things I’ve learned that have helped me perfect it:
- Don’t rush the setting time: The tart needs time to firm up in the fridge. Even though it’s tempting to dig in right away, letting it set properly ensures the filling maintains its smooth, creamy texture.
- Use freshly squeezed lemon juice: The lemon flavor is the star of this tart, so using fresh juice really makes a difference. Bottled lemon juice just doesn’t have the same punch.
- Experiment with the base: While the traditional digestive biscuit base is wonderful, playing around with different biscuits or adding spices to the crust can elevate the flavor.
- Serve chilled: This tart is best served cold. I’ve learned the hard way that it’s less satisfying if it’s at room temperature, so always chill it for the recommended time.
