Lemon Cheesecake

Who doesn't love a smooth, sweet-sour citrus flavor? Recently, cakes with lime or lemon flavor have become extremely popular, like the well-known loaf cake, which I also find extremely delicious. Although I didn't bake a loaf cake, my cheesecake manages to captures perfectly the intense lemon flavor that I was aiming for, without adding any sort of lemon essence. I decided to combine 2 of my favorite recipes, taking my classic cheesecake recipe (found also here) and the lemon curd recipe that I used for my tart (found also here). While most of previous ingredients and instructions do not change, I made some slight adjustments for the cheesecake, making less cheese mixture. That is because I decided to make the lemon curd the star of the cake and tip the scale in its favor, so too much cheese would have slightly prevented that. In this case, less is actually better. This being said, let's get to work!

*For this recipe I used a round baking tray with the diameter of 26 cm

For the base:

• 60 g unsalted butter, and a little extra for greasing the tray
• 200 g digestive biscuits

First, I greased the baking tray with butter and I covered its base with baking paper. Then I preheated the oven at 150 degrees Celsius/ level 2 on gas and in the meantime I started preparing the biscuit base.

In a kitchen robot I crushed the biscuits until they had the texture of breadcrumbs. You can also do this step by hand. Just put the biscuits in a bag, cover it with a kitchen towel and find something heavy, like a meat hammer or even an empty wine bottle to crush it until the biscuits inside have the right texture. After my biscuits were ready, I mixed them with the melted butter. If you are using a kitchen robot it will be easier for you to mix them, but by hand is also fine. I added the mixture in my baking tray, spreading it evenly, and then I used the bottom of a glass (you can also use your hands) to press it into the tray and make sure it is well compressed and even. I baked the biscuit base at 150 Celsius for 10 minutes, then I let it completely cool down.

For the cheese mixture:

• 250 g cream cheese (I used Philadelphia) 
• 250 ricotta
• 250 g mascarpone
• 3 large eggs
• 100 g granulated sugar
• 1 Tbsp. semolina
• 2 Tbsp. vanilla essence
• juice and zest from one lemon
• 2 Tbsp. cognac

Next, in a bowl I mixed the cheese with the sugar and semolina. Then I added the eggs, one by one, until fully incorporated, and lastly I added the vanilla, lemon and cognac. I poured the mixture over my biscuit base and I baked it at the same temperature for 80-90 minutes, until it became golden and the sides were golden brown. Try to pay attention to your cake after 70 minutes have passed.

! Even though the cake is baked, the mixture will still be soft and creamy, therefore you need to leave the cake completely cool down, so the cheese mixture can fully thicken. I left my cake to cool down in the oven, with the door open, which I also recommend you to do.

For the lemon curd: 

• 5 egg yolks
• 100 ml lemon juice
• zest from 2 big lemons
• 210 g granulated sugar
• 100 g butter high in fat

First I poured my freshly squeezed lemon juice through a strainer, to keep the pulp out. I put then all the ingredients above in a heat-resistant bowl which I put at Bain-Marie* for aprox. 20 minutes, continuously stirring, until the mixture became thick and shiny. It is important to stir slowly, in one direction, to prevent the mixture from separating. After the curd was ready I let it cool down and I poured it over the cheesecake, which I left over night (or at least 6 hours) in the fridge, until the curd thickened and had a jelly-like texture.

Feel free to decorate your cheesecake as you wish, I went for some fresh lemon slices and mint leaves for some extra color.

*Bain-Marie= heating our mixture over a pot of hot, almost simmering, NOT BOILING water, where our bowl does not touch the water in the pot. This technique is used because the steam created is a more gentle source of heat than the direct heat of the stove which could ruin our dish.

 Enjoy! :)
