How to use frozen fruit
Create a vinaigrette.
A basic vinaigrette is a mix of acid and fat. For example, one part vinegar or lemon juice, and three to four parts olive oil.

Options:
[A]. To make a fruit vinaigrette, thaw some frozen fruit and puree it in a blender. Then add the mixture to your chosen acidic liquid.
[B]. If you're designing an appetizer, you might want to experiment with adding in raw fruit to keep the flavors balanced. You'll want a single-serving vinaigrette, and less ricotta by serving it separately.
[C]. Instead of creating a mix or starting with equal parts lemon juice and olive oil, try making a batch of fruit popsicles and putting an additional lump of sugar into the mixture. Alternately, you can create your own, purchased plain popsicle mix using unprocessed fruits, fat, water, and ice.
[D]. Add sugar as desired, then mix them all together. Place the finished vinaigrette on the stove top, and heat until the sugar dissolves.
The answer is:
[A].
