Instructions to Make Mary Berry Key Lime Cheesecake

Follow these steps to make Mary Berry’s key lime cheesecake recipe:

Step 1: Prepare the base.

Grease the base and sides of the springform tin with some butter or spray oil. Crush the digestive biscuits in a food processor or in a ziplock bag with a rolling pin until they resemble fine crumbs. Transfer them to a large mixing bowl and add the melted butter. Mix well until the mixture is moist and clumpy. Press the mixture evenly and firmly into the base of the prepared tin, using the back of a spoon or a glass. Refrigerate for at least 15 minutes to set.

Step 2: Prepare the filling.

In the same mixing bowl, beat the cream cheese with a spatula or a wooden spoon until smooth and creamy. Add the condensed milk and mix well until combined. Add the lime zest and juice and mix again until the mixture is thick and glossy. Spoon the filling over the biscuit base and spread it evenly with a palette knife or a spatula. Refrigerate for at least 4 hours or overnight to set.

Step 3: Prepare the topping.

Whip the double cream with a whisk or an electric mixer until soft peaks form. Transfer the whipped cream to a piping bag fitted with a star nozzle, if using, or just use a spoon. Pipe or dollop the whipped cream around the edge of the cheesecake, leaving some space in the center. Sprinkle some lime zest over the whipped cream and arrange some lime slices in the center. Refrigerate until ready to serve.

Step 4: Serve and Enjoy

Enjoy! To serve, run a knife around the edge of the tin and release the springform. Cut into slices and enjoy your delicious key lime cheesecake!

Pro Tips to Make Perfect Mary Berry Key Lime Cheesecake

Enhance your cheesecake-making skills with these expert tips to ensure a delectable Mary Berry Key Lime Cheesecake every time:

  • Opt for Full-Fat Cream Cheese: Full-fat cream cheese is essential for the desired creamy texture and rich flavor. Lighter versions might not set correctly and can dilute the taste.

  • Fresh Limes for Zest and Flavor: Utilize fresh limes for their vibrant zest and juice, offering a natural and robust flavor. You’ll need about 5 to 6 limes for this recipe.
  • Mix Just Right: Once you add the lime juice, mix until just combined. Overmixing can lead to a runny or split filling.

Here are some frequently asked questions about Mary Berry’s key lime cheesecake recipe:

Can I make Mary Berry’s Key Lime Cheesecake ahead of time?

Yes, this is actually one of the best desserts to make ahead! Prepare and chill the cheesecake as directed, usually overnight. It allows the flavors to meld and the cheesecake to firm up, making it easier to slice. Just ensure it’s kept in the fridge until you’re ready to serve.

How can I ensure my no-bake cheesecake sets properly?

To ensure your cheesecake sets, make sure to:

  • Use full-fat cream cheese which has less water content and sets firmer.
  • Mix the filling just enough to combine the ingredients well but not so much that it introduces too many air bubbles or breaks down the structure of the cream cheese.
  • Allow ample chilling time; at least 4 hours, though overnight is often best for a firm set.

What’s the best way to get a smooth top on my cheesecake?

After pouring the filling onto the biscuit base, gently shake or tap the tin on the counter to let any air bubbles rise to the top and pop. You can also smooth the top with an offset spatula or the back of a spoon. Remember, a few imperfections won’t affect the delicious taste!

Can I use regular limes instead of key limes?

Yes, you can. Key limes are smaller and more aromatic than regular limes, but they are not always easy to find. You can use regular limes instead, but you may need to adjust the amount of juice and zest depending on how tart or sweet you like your cheesecake.

Can I make this cheesecake vegan or dairy-free?

Yes, you can. You can use vegan or dairy-free alternatives for the cream cheese, condensed milk, butter, and cream. There are many brands and products available in the market that you can choose from. Just make sure to check the labels and ingredients for any allergens or additives that you may want to avoid.
