Sungold tomatoes peak in August and most bars use them once, halved on a garnish pick. Salted and hung overnight, a kilo of them drips into clear golden water that tastes like the whole fruit: sweet, savory, quietly acidic. Stirred with gin and a basil vermouth, it makes a martini that reads classic in the glass and tastes like the market. No heat, no machine, two days of lead time.
The drink
This is a martini build: gin, vermouth, and 30 ml of tomato water where the extra dilution would normally go. The tomato water is clarified by gravity alone, so the drink pours pale gold and crystal clear. The vermouth carries basil, tomato’s oldest partner, from a 30-minute maceration. Everything is cold process. The tomato never sees heat, which is why the water tastes like a raw sungold and not like sauce.
The clarification method matters. Blend the tomatoes hard or press the pulp and you extract pectin and bitterness, and the water comes out murky and needs fining. Break the fruit gently, salt it, and let it drip. The salt pulls the water out for you, seasons the drink, and you skip the centrifuge this recipe does not need.
Finished-drink targets
ABV: ~21%
Clarity: crystal clear, pale gold. Gravity drip, no pressing
Salt: carried in the tomato water, ~8 g/kg fruit
Serve: ~130 ml, chilled Nick & Nora, no ice
Prep 1: sungold tomato water
Spec, per 1,000 g sungold tomatoes
8 g fine salt
1. Pulse the tomatoes with the salt in a food processor,
3 or 4 short pulses. Broken, not puréed. Crushed seeds
read bitter.
2. Rest 30 minutes at room temperature. The salt starts
pulling the water.
3. Hang in a muslin cloth or Superbag over a container in
the fridge, 12 hours. Do not press, do not squeeze.
Pressing clouds it and undoes the whole point.
4. If the last drops clouded the batch, pass it once
through a coffee filter.
Yield ~600 g clear water per kg of fruit, 20 serves.
Three days refrigerated. Freeze what service will not use
in 250 g portions; it thaws clear.
Taste it before you bottle it. Sungolds at peak carry their own sugar-acid balance and most batches need nothing. If a batch tastes flat, whisk in 1 g citric acid per 1,000 g of water and taste again. That is the entire adjustment.
Prep 2: basil vermouth
Spec, per 750 ml dry vermouth
20 g fresh basil leaves, whole
1. Macerate the leaves in the vermouth at room temperature,
30 minutes. Whole leaves, no blending. Bruised basil goes
dark and bitter.
2. Strain through a coffee filter. Bottle, label, date,
refrigerate.
Yield ~740 ml, 37 serves. Three weeks refrigerated,
like any open vermouth.
The build
Spec, per serve
60 ml London dry gin
20 ml basil vermouth
30 ml sungold tomato water
1. Stir over ice ~30 seconds to 20–25% dilution.
2. Fine-strain into a chilled Nick & Nora.
3. Garnish: one sungold, halved, on a pick across the rim.
Nothing else.
Service batch, per liter (spirit only)
750 ml London dry gin
250 ml basil vermouth
1. Combine, bottle, refrigerate on the rail.
2. Service: 80 ml batch, 30 ml tomato water, stir, strain,
garnish.
12.5 serves per liter. Holds 1 month refrigerated; the
vermouth is the clock. The tomato water stays out of the
batch on purpose: batch the shelf-stable spirits, add the
perishable fresh at the stir.
The drink is served up, so the glass gets no ice, ever. Cold comes from the stir and the chilled glass. A freezer batch does not work here; the tomato water’s three-day clock would put the whole liter on a countdown.
The operator math
Ingredient cost per serve, using a $20 well London dry:
- Gin, 60 ml: ~$1.60
- Basil vermouth, 20 ml: ~$0.30 (a $10 dry vermouth plus a bunch of basil makes 37 serves)
- Tomato water, 30 ml: ~$0.85 (sungolds at ~$5 a pint; one kilo makes 20 serves)
- Garnish: ~$0.10
Call it $2.85 a serve. At $19 on the menu that is a 15% pour cost, and $19 is where a house martini with a story sits comfortably in New York right now. The tomato is the expensive line here and it is still under a dollar. The same water also makes the NA listing: 60 ml tomato water, 90 ml soda, over ice with a basil leaf, ~$1.80 in the glass against a $9 ticket.
The larger point is the one this recipe series keeps making: peak-season produce plus a written spec beats a novelty ingredient every time. The tomato water is two steps and a cloth. What makes it a menu item instead of a one-off is the gram sheet, the yields, and the batch rule any bartender on the roster can follow.
Builds like this, with the batch sheets and prep SOPs behind them, are what a menu refresh engagement produces. If your list has no answer for August yet, fifteen minutes will tell you what it needs.
