Ingredients for Your Lemon Mousse Inspired by Mary Berry

Right then, for this little beauty, you’ll need a few bits for the gorgeous lemon curd base, and then just cream to make it wonderfully light and airy. Don’t worry if you haven’t made curd before, it’s much simpler than it sounds and Mary Berry would approve of the straightforward approach!

• For the Lemon Curd:
• 1 large egg
• 1 egg yolk
• Zest of 1 lemon (I always use a microplane for this, gets all the lovely oils out!)
• 1/4 cup fresh lemon juice (about 1 juicy lemon)
• 3 tablespoons caster sugar (this makes it nice and smooth, not too coarse)
• 3 tablespoons unsalted butter, cubed (make sure it’s cold when you add it!)
• For the Mousse:
• 1/2 cup cold double cream (make sure it’s properly chilled for the best whip)
• For Serving (Optional but lovely!):
• Extra whipped cream
• Thin lemon slices

Step-by-Step Guide to Making Lemon Mousse Inspired by Mary Berry

Okay, let’s get this delicious dessert made! It’s really quite straightforward, and the key is just being patient with the lemon curd and making sure everything is lovely and chilled. Don’t rush those chilling stages – they’re crucial for the perfect texture!

Step 1: Get a small saucepan with a few centimetres of water on the go and bring it to a gentle simmer – not a rolling boil, mind! We want gentle warmth.

Step 2: In a heatproof bowl, whisk together your egg, the extra egg yolk, all that zesty lemon peel, the fresh lemon juice, and the caster sugar. Give it a good whisk until it’s all smooth and lovely.

Step 3: Now, pop the cubes of lovely cold butter into the egg mixture. Carefully place this bowl over the simmering water. Make sure the bottom of the bowl isn’t actually touching the water, otherwise, you’ll scramble your eggs!

Step 4: Here’s where the magic happens! Stir continuously. You’ll see the butter melt and then, almost like magic, the mixture will start to thicken. Keep stirring for about 5 minutes. You’re looking for it to coat the back of a spoon nicely. If it’s too thin, give it another minute or two.

Step 5: Once it’s thickened, carefully take the bowl off the heat. Strain that gorgeous lemon curd into a clean bowl. This gets rid of any bits of zest that might have clumped and ensures a super smooth finish.

Step 6: Now, this is important for a silky texture! Press some cling film directly onto the surface of the lemon curd. This stops a skin from forming. Pop it in the fridge for at least 30 minutes, or until it’s completely cold and set. Trust me, this step is a game-changer.

Step 7: While your curd is chilling, get another mixing bowl and pop that in the fridge too. A nice cold bowl helps the cream whip up better. Pour your cold double cream into it.

Step 8: Whip that cream! Start on a low speed and gradually increase. You’re looking for firm peaks – you know, when you lift the whisk, the cream stays up and doesn’t flop over. Don’t over-whip it into butter!

Step 9: Right, take your chilled lemon curd out. Spoon about 2 tablespoons of the whipped cream into the curd and gently stir it in. This just loosens the curd a bit, making it easier to fold.

Step 10: This is the ‘folding’ bit! Add the rest of the whipped cream to the loosened lemon curd. Use a large spatula and gently fold it all together. Imagine you’re cutting through the middle and folding the mixture over. You want to keep all that lovely air in, so be gentle! Keep folding until it’s just combined and looks like a beautiful, airy mousse.

Step 11: Spoon your fabulous mousse into your serving glasses or ramekins. Smooth the tops a little with your spoon or a small spatula.

Step 12: Now, for the final chill! Pop them back in the fridge for at least an hour. This allows the flavours to meld and the mousse to set up perfectly. If you’re short on time, you can sneak them into the freezer for about 15-20 minutes, but watch them carefully!

Step 13: Just before serving, add a little extra swirl of whipped cream and a thin slice of lemon on top if you fancy. It looks so pretty and adds that extra zing!

Serving Suggestions for Your Lemon Mousse

This lovely lemon mousse is gorgeous on its own, but here are a few ideas to make it even more special:

Fresh Berries: A little handful of fresh raspberries or blueberries scattered on top adds a lovely pop of colour and a tangy contrast to the creamy lemon. Perfection!

Shortbread Biscuits: A crisp, buttery shortbread on the side is just divine. It gives you something lovely to dunk and adds a wonderful texture.

Candied Lemon Peel: If you’re feeling ambitious, a little bit of homemade candied lemon peel looks ever so elegant and adds an extra zing for true lemon lovers.

Storing and Reheating Your Lemon Mousse

This lemon mousse is best enjoyed fresh, but it keeps beautifully in the fridge for up to 2 days. Just pop a bit of cling film over the top to stop it from picking up any stray fridge smells. Honestly, the flavours get even better as it sits for a bit! I haven’t found a way to reheat it, as it’s meant to be served chilled, but if you’re planning ahead for a party, you can absolutely make the lemon curd a day or two in advance and then just whip the cream and fold it all together on the day you want to serve it. That way, it feels less like a rush!

Frequently Asked Questions About Lemon Mousse

Can I make this Lemon Mousse without eggs?

Ah, a classic question for mousse lovers! While this recipe is inspired by Mary Berry’s approach and uses eggs for that silky lemon curd base, you could try a version using agar-agar or gelatin if you’re avoiding eggs entirely. However, it will change the texture slightly. For a simpler, egg-free citrus treat, have you considered my easy lemon cupcakes? They’re also fabulously zesty!

My lemon curd split, what did I do wrong?

Oh no, that’s frustrating! Usually, if the lemon curd splits, it’s because it got a bit too hot, too fast, or was cooked unevenly. My top tip is to keep that heat gentle and stir *constantly* when it’s over the simmering water. If it does split a little, don’t despair! Sometimes whisking it vigorously off the heat, or even giving it a quick blitz with a hand blender, can bring it back together. If not, strain it really well to get the smoothest base possible.

Can I make this Lemon Mousse ahead of time?

Absolutely! This is one of the best things about this dessert. You can make the lemon curd base a day or two in advance and keep it chilled. Then, on the day you want to serve it, just whip your cream and fold it all together. It really does need that chilling time (at least an hour) for the flavours to meld and for the mousse to set up perfectly, so making it ahead is ideal. It’s a bit like my easy lemon traybake, which is even better the next day!
