I’ll break down the ingredients, the gear you’ll want, and the steps (which aren’t complicated, I promise).

Herb-Infused Prawn Negroni Cocktail Recipe

I like changing up a classic negroni with a hit of herbs and prawns. The base—gin, Campari, sweet vermouth—doesn’t get messed with, but the infused flavors and garnish? Way more savory and interesting.

Equipment

When I make this, I don’t go wild with fancy tools. A mixing glass is a must, though, since I want to stir things gently and not water everything down.

A bar spoon helps me control the stir, so I don’t overdo it. For serving, I grab a heavy rocks glass because it keeps the drink cold and fits a big ice cube.

A fine strainer is handy—nobody wants stray herbs floating around.

• Mixing glass
• Bar spoon
• Fine strainer
• Jigger for measuring
• Rocks glass
• Large ice cube mold
• Small saucepan (for herb infusion)
• Cocktail pick (for prawns and garnish)

Ingredients

I stick with equal parts gin, Campari, and sweet vermouth. For vermouth, Carpano Antica is my go-to; it just adds this rich, deep thing I love.

Fresh rosemary in the infusion gives it a savory edge that works so well with prawns.

For garnish, I skewer a couple of lightly grilled prawns. They bring this subtle briny aroma that plays off the herbs in the drink.

Go for big, good-quality prawns if you can. Makes a difference.

• 1 oz gin
• 1 oz Campari
• 1 oz sweet vermouth (Carpano Antica recommended)
• 1 sprig fresh rosemary
• 2 large prawns, peeled and deveined
• Olive oil, for brushing prawns
• Large ice cube
• Optional: orange peel for garnish

Instructions

First, I infuse the gin with rosemary. Just a quick simmer in a small saucepan—the herb releases its flavor but doesn’t overpower the gin.

Let it cool, then strain out the rosemary to keep things clear.

Then, I grill or pan-sear the prawns with a little olive oil. Once they’re cooked, I slide them onto a cocktail pick for garnish.

• Infuse gin with rosemary for about 10 minutes, then strain.
• Chill the mixing glass with ice.
• Add rosemary-infused gin, Campari, and Carpano Antica sweet vermouth.
• Stir with bar spoon until well chilled.
• Strain into a rocks glass over a large ice cube.
• Garnish with grilled prawns and an optional orange peel.

Notes

For me, rosemary is the best choice for infusion because it stands up to the strong Campari and vermouth flavors. If I’m in the mood for something softer, I’ll swap in thyme.

Carpano Antica gives this drink a rounder sweetness, but honestly, any decent sweet vermouth will do. I try not to overcook the prawns—they should stay tender, not rubbery.

And about that garnish—it’s not just for looks. The aroma from the prawns hits you with every sip. I like to serve them warm on the skewer for a nice contrast with the chilled cocktail.

Tasting Notes

So, the first sip hits with that unmistakable bitterness of a classic Negroni. But then the herb infusion steps in, softening things up and adding this fresh, green vibe that kind of hangs around on my palate.

The prawn garnish? That was unexpected. It brings a gentle briny note that actually works with the herbal tones, making the drink feel like more than just your average aromatic cocktail.

I can still pick out the balance between sweet vermouth and bitter Campari, but the herbs nudge the attention elsewhere. Instead of just the usual citrus and bitterness, I’m getting these subtle earthy flavors—makes the whole thing feel a bit more layered, honestly.

As an Italian aperitivo, it still fits right in before dinner. The herbs and prawn add this savory twist, and honestly, it kind of makes me want to snack on something small while I sip.

The texture? Still smooth and light, nothing too heavy. But it’s the aroma that really stands out to me—each sip brings that classic bitter-sweet combo, plus the savory scent from the garnish, and it just feels… well, more interesting than usual.
