As others have commented, the drink is much elevated by the addition of 15ml of banana liqueur (giffard here)

Live a little, and use the whole banana! Nice looking frozen drink - I used Smith & Cross, but likely could have used a 80 proof white rum and it would have been fine. A nice poolside/hot weather drink.

Delicious. Although we thought we secured an overripe enough banana, apparently it was not up to the task so we followed others’ guidance and added 20 ml of banana liqueur total (we had two drinks). Additionally, feeling it might need just a bit something extra, we added to each drink 3 drops of sea salt solution (4 water : 1 sea salt; (first tried 2 then went for one more). Additionally, we didn’t have yellow chartreuse so used Genepy le Chamois.

6.5 oz WEIGHTED ice for me. yield was 12 oz. it was great but something seems to be missing... added 20ml banana liquor.

I have tried to sub the yellow chartreuse with Strega liqueur (two thirds cheaper here in Italy) and at the moment I am not seen much of a difference, though If I were a billionaire I'd probably stick to the Yellow chartreuse to be fair.

10-15ml crème de banane (not some old bottom shelf banana liqueur, but something proper like Giffard) is an excellent addition.

Subbing the lime for ~30ml lemon also fits the flavor profile rather well

I was out of falernum but tried to approximate it with orgeat, a couple of dashes of Bittermens Emakulele Tiki bitters and a couple of dashes of Dr Adam Elmegirab’s Dead Rabbit Orinoco Bitters and the result turned out to be very tasty indeed.

As a side note, I also added a small amount of xanthan gum to help keep the emulsion stable for longer (as generally recommended for blended drinks by The Educated Barfly YouTube channel).

I used a full banana and added 10ml of banana liqueur.

Finally, a clever use of overripe bananas.
I used 20 ml Stroh rum 80% because I don't have any white overproof rum. The Stroh rum gave the drink a very nice colour.
A one 9 oz scoop of crushed, would that be roughly 150 grams?
Sip this one slowly, it's strong.

Oh so good!. Only had a 1/2 shot of Chartreuse so added 1/2 shot of Giffords Banana. On hot evening this is a Banana Slushie heaven with a KICK. A real winner - though be warned the Wray & Nephew comes through to the last drop so not to many,
ps - my banana was definitely ripe

Wanted to like this but really didn’t. Definitely needed an overripe banana to sweeten it up, which we did not use. Doubt I’ll make it again.

Always on the hunt for a cocktail. Just bought a bottle of falernum to add to our "pandemic" hobby...this cocktail is a winner. The Wray & Nephew Overproof is a power house, it plays nice once combined and blended. Banana, nice touch. I feel it could be a "just" tich sweeter. Always the opportunity to make a tweek of your own!?

I tried this one a couple of weeks ago. So tasty, better than the original nucelar daiquiri IMHO

Nice to see Hawksmoor mentioned here, our favorite London restaurants, when we visit. May just try this one, just need to buy a banana. On holiday right now so many cocktails being mixed daily. Happy Rum Day Simon and team.
