Strain the yogurt through a colander lined with a cheesecloth over night. Drink the yogurt whey (the liquid), or use it in cooking as it is full of nutrients.
Add the lemon powder (or the lemon juice) to the strained yogurt, and combine it until creamy and soft with a whisk.
Mix well until creamy just like this.
Combine the heavy cream and the sugar, and beat until silky and stiff peaks form. 15 g of sugar will make a light flavored cake. Please adjust the amount of sugar to your preference.
Gently fold the strained yogurt from Step 3 into the whipped cream from Step 4 with a rubber spatula in a cutting motion and it is done!
To mix evenly, combine 1/3 of the yogurt with the cream first, then add the remaining yogurt.
Serve it into a container gently using a spoon, and enjoy it with your favorite jam or sauce.
You can also enjoy it parfait-style by layering it with sponge cake or cookies!
