My favorite cocktail is maybe plain, but very tasty, that's why i'm gonna post it, even if i'll loose the contest:

You need:
- 5 frozen strawberries
- 5cl lime juice
- 3cl lemon juice
- 1 teaspoon sugar
- cracked ice
- whipped cream
- coconut flakes
- half orange slice
- 1 straw
- 1 cocktail umbrella

Add the strawberries, lime juice, lemon juice and the suger into a blender (besides the cracked ice) and blend them until you get a creamy liquid. You may, but musn't, add some strawberry syrup here. Put the cracked ice into a cocktail glass with a belly and pour the blended liquid into the glass. put some whipped cream on the top and spread some coconut flakes over the whipped cream. dress with the orange slice, the straw and the umbrella. Enjoy!
