    Very citrus-y and creamy, and so easy to make. This was a hit with my family.

    First off: Plan to eat this the same day you make it!!! Why? The citric juices begin to "cook" the dairy ingredients and the texture is not as good the next day. I make this for summer night meals when lemon and lime flavors are especially appreciated. This one takes a bit of time and effort but it is made ahead of time anyway to cool in the fridge. I put in more than 1 Tbsp. of lime--maybe 2 Tablespoons. I also sometimes add green or yellow food coloring b/c without it, it looks a bit bland. The flavor is very good however. Suitable for company.
