This Sour Frankenstein Halloween Cocktail is perfect for your spooky party – it’s really just a cucumber margarita in disguise!
Ingredients and substitutions
- Tequila – this drink would also be good with vodka, gin, rum or whisky. Leave out the alcohol for a fun mocktail!
Margarita mix
- Limes – the limes are pretty integral to this recipe, so I wouldn’t recommend leaving them out.
- Cucumber – you can leave out the cucumber and add 2 extra limes instead.
- Salt – to taste.
Simple syrup
- Sugar – use any cup-for-cup sugar substitute of your choice.
Fake blood
- Corn syrup – use sugar dissolved in warm water or honey instead.
- Red food colouring – you’ll need the red to get the blood colour, but green would also be fun.
- Cornstarch – potato starch might also work.
