A Blue Sea Martini is as refreshing as a cool ocean breeze on a summer evening. With its striking blue hue and perfectly balanced sweet-citrus flavor, this cocktail is a showstopper at any gathering. It’s easy to make, requires just a few ingredients, and brings a little coastal magic to your glass.

Blue Sea Martini
I’ve made this drink countless times, and here’s a tip I learned while perfecting it: chilling your glass beforehand makes all the difference in keeping the flavors crisp and refreshing.
Ingredients
You’ll need:
- 2 oz (60ml) vodka
- 1 oz (30ml) blue curaçao
- 1/2 oz (15ml) fresh lemon juice
- 1/2 oz (15ml) simple syrup
- Ice cubes (for shaking)
For serving:
- Lemon twist or maraschino cherry (optional garnish)
- Chilled Martini glass (or Coupe glass as an alternative)
How to Make a Blue Sea Martini
- Fill a cocktail shaker with ice cubes.
- Pour in vodka, blue curaçao, lemon juice, and simple syrup.
- Shake well for about 15 seconds, until the mixture is well-chilled.
- Strain into a chilled Martini glass.
- Garnish with a lemon twist or maraschino cherry for an extra touch of elegance.
Tips for the Perfect Blue Sea Martini
- Chill your glass before serving for a crisper sip. Just pop it in the freezer for a few minutes.
- Use good-quality ice to prevent the drink from getting watered down too quickly.
- Adjust the sweetness by adding more or less simple syrup to suit your taste.
- Prefer a slightly tangier version? Swap lemon juice for lime juice for a little extra zing.
Serving & Pairing Ideas
A Blue Sea Martini pairs beautifully with light, fresh flavors. Here are some great options:
- Seafood – Think shrimp cocktail, oysters, or grilled fish. The citrusy notes in the drink complement seafood perfectly.
- Spicy appetizers – The sweetness of the cocktail balances the heat of spicy wings or jalapeño poppers.
- Crisp salads – A simple arugula or citrus-dressed salad makes for a refreshing pairing.
I love sipping this drink with a plate of fresh ceviche—it’s like a mini vacation in every bite!

Common Questions
Can I make this cocktail ahead of time?
Yes! Mix everything except the ice and keep it chilled. Shake with ice just before serving for the freshest taste.
What if I don’t have blue curaçao?
Blue curaçao gives the drink its signature color and slight citrusy bitterness. If you don’t have it, you can use orange liqueur with a few drops of blue food coloring, though the taste will be slightly different.
How can I make it less sweet?
Reduce the simple syrup or replace it with a natural sweetener like agave or honey.
What’s the best way to get that perfect garnish?
Use a vegetable peeler to create a thin lemon twist and give it a slight twist over the glass to release its natural oils before dropping it in.
A Blue Sea Martini is the kind of cocktail that feels like a special occasion, even if you’re just unwinding after a long day. Whether you’re making it for a party or treating yourself to a little escape, this drink is sure to impress. Cheers! 🍸
