To get passion fruit juice, simply sieve it through a strainer. The type of holes in it will determine whether some pulp goes through or not.
Divide ½ cup fresh strawberries and 5 tablespoons sugar between two glasses. With a muddler, start crushing the fruit with the sugar, until it becomes syrupy. Do this slowly and take your time. It's the base of the drink.
Add ice to almost fill each glass, and then pour ½ cup passion fruit juice, dividing equally between the glasses.
Add 4 ounces Cachaça, dividing equally between the glasses.
Stir until it mixes well, decorate with a strawberry half and serve with cocktail straws.
Notes
Ice: I use regular ice from my home freezer. But if you have access to larger, more professional ice cubes, so much better. They last longer, so the drink takes longer to water down.Glasses: use glasses that can hold everything and have a flat base. You need it to muddle without breaking it. Don't use martini glasses for example.Fruit: be careful not to add too much. Test it with one drink. You should taste the fruits and the liquor and have enough space for the ice.Personal taste: adjust sugar, ice, and cachaca to your taste. And use that ratio as a guide no matter what fruit you use.Sweetener: you can use simple syrup instead of the sugar. To make it simply heat the same amount of sugar and water (½ a cup of each for example), and when it comes to a boil remove it from the heat. Let cool completely and keep refrigerated.
