Seaglass Rose Recipe

Chill

Place a coupe or martini glass in the freezer or fill it with ice water to chill while you mix the cocktail.

Combine ingredients

In a cocktail shaker add 2 tbs gin, 0.5 tbs dry vermouth, 0.5 tbs elderflower liqueur, 2 tbs white cranberry juice, 0.5 tbs fresh lemon juice, 0.25 tsp blue curaçao, 2 tsp rose water and 0.5 tsp simple syrup.

Add egg white (optional)

If using egg white for a silky foam, add 0.5 egg white to the shaker. (Use pasteurized egg white if preferred.)

Dry shake

Seal the shaker and shake vigorously without ice for 10–15 seconds to emulsify the egg white and integrate flavors; this builds foam and helps the blue tint incorporate evenly for a seaglass effect.

Wet shake

Add about 1 cup of ice to the shaker. Shake vigorously for 12–15 seconds until the shaker is well chilled on the outside (hard shake).

Double strain

Discard the ice/water from your chilled glass. Using the shaker's strainer and a fine strainer, double-strain the cocktail into the chilled coupe to remove ice shards and ensure a silky texture and clear seaglass appearance.

Garnish

Express a lemon twist over the cocktail to release oils, then rim the glass with the twist and drop it in. Float a single edible rose petal gently on the foam. The small amount of blue curaçao will create a pale sea-glass tint while rose water gives a delicate floral aroma.

Serve

Serve immediately. Encourage guests to sip slowly to appreciate the layered floral and citrus notes and the visual seaglass hue.

If you prefer non-alcoholic, replace gin and vermouth with a botanical non-alcoholic gin substitute and use elderflower syrup (reduce simple syrup accordingly). Adjust blue curaçao to a drop or two of blue food-grade tincture or butterfly-pea tea concentrate for color.

To avoid raw egg, use 15–20 ml (about 0.5 oz) pasteurized liquid egg white or 3/4 tsp aquafaba (chickpea brine) as a vegan alternative; shake the same way.

Taste and adjust sweetness or acidity: add another 1/4–1/2 tsp simple syrup if too tart, or another 1/4 tbs lemon juice if it needs brightness.
