Way back in the day I shared a wonderfully easy alternative to classicly churned ice cream with my first semifreddo recipe. We'll talk more about what semifreddo actually is in detail later on in this post, but for now, let me just tell you that it's an amazing lighter alternative to ice cream. Much like ice cream though, it's a versatile base that can be flavored with just about anything including sauces and mix-in items. This delicious version has a vanilla-lemon base that's flavored with swirls of homemade blueberry sauce, subtle lemon flavor, and bits of homemade cheesecake bites throughout which add even more creaminess. All the flavor and texture combinations in this compact light dessert really make this the perfect summer treat.
