A bright, fizzy gin cocktail with a twist on grapefruit soda and fresh herbal and vegetal notes. Uses slightly reduced gin quantity, swaps cucumber ribbons for thin slices of zucchini, and thyme for rosemary to add piney aroma. The citrus gets charred to hint smoky bitterness but torches replaced by skillet pan-searing for easier kitchens. Glaçons chilled thoroughly. Garnish changed to grilled grapefruit slice. Served with toasted halloumi bites instead of cheese-cucumber combos for salt contrast. Texture and aroma layered with bubbles, herbal hints, and bitterness. A brisk, light drink with complexity atop quick summer gatherings.

Bright fizz hitting lips first. The tart grapefruit soda gives sharp citrus punch—something sweet but not saccharine. Gin reduced slightly; less boozy haze, more bouquet showing. Swapping cucumber for zucchini skin ribbons brings a woody, subtle raw crunch instead of watery freshness. Rosemary over thyme for a more robust piney scent, stands up better to gin and charred citrus. Grapefruit sliced thin then seared, no torch needed; the pan caramelizes sugars, a quick smell of burnt citrus that flips the flavor. Glaçons crucial, packed tight and cold, chilling without rapid melt slows dilution. Halloumi toasties alongside provide salty, chewing contrast to smooth sip. Tried this on breezy evenings; complexity without fuss. Fizz doesn’t fade fast, it lingers with vegetal-whiff and herb bite. Easy swaps and tweaks make all the difference, nothing rigid. Original idea took shape, but my few adjustments gave it sharper edge, more body, less plain refreshment. Summer in a glass.
Ingredients
- 1 thin slice of grapefruit
- 25 ml gin (slightly less than 2 tbsp)
- 130 ml grapefruit soda (store brand or homemade, lightly sweetened)
- 1 thin strip of zucchini, skin on, shaved with peeler
- 1 small fresh rosemary sprig
- Plenty of ice cubes
About the ingredients
zucchini skin shavings replace cucumber ribbons here—less watery, more textured and earthy. Keep peel on, that’s where gentle herbs and bitterness sit. Rosemary sprig over thyme changes cocktail vibe dramatically; rosemary lingers on the nose longer, more assertive woody. Grapefruit slice pan-seared, not torched—common kitchens lack torches but heat and contact yield caramelization on surface, quicker, less fussy, and smoky tone builds. Use grapefruit soda that’s lightly sweetened—too much sugar overwhelms gin’s botanicals and dry edge. Gin amount lowered slightly, helps keep cocktail crisp, balance easier. Ice critical: use big clear cubes or crushed packed tight; prevents melt dilution too fast, keeps bubbles lively. If halloumi unavailable, try grilled tofu cubes sprinkled with smoked paprika, keeps salty contrast and chew. Always prep drink glasses with cold beforehand to hold chill longer, avoid cloudy water from quick melting. The ritual of flames or heat on citrus isn’t just decoration—it’s flavor shift that changes cocktail depth wildly. Fresh herbs should be whole sprigs, bruised slightly to release oils but not torn to bits—no bitter over-extract.
Method
- Heat a heavy skillet over medium-high until very hot but not smoking. Place the grapefruit slice in the pan. Press lightly, cook about 1 minute each side till spots turn dark brown, edges curling and caramel scent pops. Watch closely. If no torch at hand, pan searing adds smoky notes and crisps surface—skip if you want clean acidity.
- Fill a rocks glass 3/4 full with fresh ice cubes chilled beforehand (avoid melting water dilution). Pour gin over ice, swirl gently to chill.
- Add grapefruit soda slowly, so fizz rises but stays balanced—avoid flat drink or foam overflow.
- Drop in zucchini strip and rosemary sprig; the zucchini gives vegetal crunch, lightly bitter green note, rosemary yanks pine aroma that cuts sweetness.
- Lay the warm pan-seared grapefruit slice on top; aroma changes as it warms the glass rim. It gives bitter-sweet smoke, complements gin botanicals.
- Serve bedside with toasted halloumi cubes, salty and squeaky, pairs with vegetal freshness of zucchini and herbal pine from rosemary.
Cooking tips
Heat pan fully before grapefruit slice—a too-cool pan means no caramelization, just soggy cooking; look for dimpled browned spots appearing quickly. Keep aroma in mind—like popcorn crackle in pan—sign you’re in golden window not burnt black. When ice fills glass 3/4 full, add gin first, swirl gently; this chills liquor without water loss. Pour soda slowly over edge; fizz must build slowly or you flatten drink, foam rushes everywhere. Add zucchini and rosemary last; gentle stir to marry flavors without crushing herbs. Placing warm grapefruit on cocktail top is last step; enough heat to release oils but avoid cooking drink cold inside. Serve immediately; bubbles mute fast with delay. Toast and cube halloumi ahead, store warm but off heat for chewy salty bites. If you don’t have big ice, crush your own from frozen bottles. Avoid shaking cocktail—delicate carbonation destroyed. Experiment with herb substitution on occasion—tarragon, basil, or sage—but rosemary offers best piney lift in this combo. If no fresh herbs, drop a tiny dried sprinkle but flavor is weaker. Watch garnishes closely; oversteeping herbs can turn bitterness harsh. This drink thrives on balance of fresh, cold, bitter, burnt, and herbal; eye and nose guidance work better than timers. Have a tray ready for fast plating and serving; fizz dies fast once poured.
Chef's notes
- 💡 Heat pan fully before grapefruit slice hits surface. Wait for dimpled spots, quick caramel brown. Beware soggy pulp from low heat. Smell like popcorn cracking in pan means right moment; too dark, bitter notes creep fast. Pan contact time controls smoke intensity; watch edges curl, don’t burn black.
- 💡 Ice matters. Use big clear cubes or crushed packed tight. Keeps drink cold longer, slows dilution. Avoid cloudy water fast melt kills fizz speed. Glass chilled ahead better—prevents fast temp drop. Add gin over ice first, swirl gently. No shaking or too rough fizz disappears, flat drink happens.
- 💡 Add grapefruit soda slowly, edge of glass or side pour. Fizzy bubble layer stays balanced longer. Pour fast and foam explodes ruining textures and aromas. Bubble retention key here. Don’t overload liquid or fizz flattens quick, drink dulls.
- 💡 Zucchini skin shavings replace cucumber ribbons; less watery, more chew. Keep peel on—bitter freshness sits there. Rosemary whole sprigs bruised lightly, no tearing. Too much bruising leaches harsh flavors, herbs turn bitter. Pine aroma cuts sweetness well, thyme swapped out for robust scent.
- 💡 If halloumi missing, grilled tofu cubes with smoked paprika works. Keeps chew, salt contrast, smoky punch. Toast cubes before serving, warm but off heat to keep firm texture. Prep garnishes ready: warm grapefruit placed last releases oils slowly but no cooking inside drink; aroma shifts as glass warms.
Common questions
Why pan sear grapefruit slice?
Torch heat not always handy; skillet pan sear caramelizes sugars quick. Produces smoky, bitter notes, crisp edges. Low heat equals soggy slice, no good. Watch dimpled brown spots for cue. Aroma like popcorn crackle signals done. Avoid burned black parts.
Can I swap rosemary for other herbs?
Sure, tarragon, basil, or sage possible but pine aroma missing then. Rosemary lingers stronger on nose; stronger than thyme here. If no fresh herbs, dried sprinkle okay but taste weaker. Whole sprigs bruised lightly preferred to release oils slowly without bitterness.
What if fizz disappears fast?
Pour soda slow over glass edge. Avoid splashing or stirring too hard after. Use big ice cubes or packed crushed ice, slows melt dilution, keeps bubbles lively longer. Shaking kills carbonation fast. Always chill glass first to keep temp steady.
How to store leftovers or prep ahead?
No storing mixed drinks. Prep garnishes like halloumi cubes ahead but keep warm separate. Ice definitely chilled and ready before serving. Soda pre-chilled too. Avoid pre-mixing with ice to stop dilution. If forced, keep separate components cold till last moment.
