Blueberries and cream

Even though it's too simple to really count as a recipe, this is one of my favorite summer desserts. Also something you can easily make with one hand. The ingredients, as you may have already guessed, are:

1. blueberries
2. cream (or half-and-half, or whole milk. If you're using anything with less than 4% fat, just eat the blueberries plain.)
3. sugar (optional)


Do I really need to write assembly instructions?
