I like cheesecakes, particularly light and rare cheesecakes. Both desserts were originally created in Japan. They are either mostly unavailable or pretty pricy in the US

I followed some online recipes of light cheesecakes, but they all failed. The biggest problems were that my light cheesecakes were not as fluffy and had a foamy top layer and dense bottom layer.

With frustration, I turned my attention to rare cheesecakes which refers to unbaked cheesecakes. The most popular rare cheesecake recipes use large amount of heavy cream and lemon juice. When I visited New York City, a friend of mine strongly recommended a bakery that started in around late 1970s. I chose a piece of very smooth rare cheesecake with beautiful presentation, balanced sourness, and a silky sensation. It turned out the main ingredient was very smooth whipped heavy cream, which is not very healthy.

So, I decided to make a tweak to popular online recipes by adding some healthy ingredients such as whole milk, Greek yogurt or kefir, and fresh blueberries. In addition, I reduce the usage of or eliminate heavy cream. If you decide to give it a try, please bear in mind, this recipe is versatile. You may adjust amount of each ingredient to your preference. The only thing you need to pay attention is balancing the sourness. You should be happy with what you get if you follow it properly.
