A cocktail shaker would be great, if not, just stir it all up well in a glass/jug.
Instructions
Blackberry Syrup (needs to be made earlier and chilled)
Place all the ingredients in a saucepan and bring to a gentle boil.
300 g blackberries, 100 g sugar, 125 ml water, 1 Tbsp lemon juice
Lower the heat right down and simmer for 15 minutes, by which time the fruit will be soft and falling apart. Squash the fruit with the back of a spoon or a fork to release more juice.
Strain into a jug/bowl with a strainer double lined with muslin/cheese cloth. Or strain in twice with a fine sieve. Basically, we want a clear syrup with no bits.
Place in the fridge to chill.
Let's make the Bloody Margarita
Run a lime slice all around the rim of a glass.
Dip the glass rim into the black lava salt, coating well.
some black lava salt in a saucer
Place everything into a shaker and shake to mix and chill. Start with ½ part blackberry syrup.
60 ml tequila, 30 ml aperol, 30 ml blackberry syrup (recipe below), 30 ml lime juice (keep the lime to prep the glass)
Taste and add more syrup if you like it sweeter. I do.
Pour into the glass, minus the ice cubes, and start sipping!
