I have had this before and upped the lime as it was a touch sweet. Retried using Ferrand Tropical Dry Curacao (thankyou for the tip Paloma :)
This is so much better as the Rum and spices are to the fore and the sweetness is perfect without any modification.
Adding the Ferrand version as Oh My Gosh!

In our opinion this cocktail is simply too sweet. Next time I would omit the sugar syrup. Some drops of saline solution and/or a bit of bitters could deepen it.

If we can be allowed to call this a 'Between the Sheets' variant, then it is the only variant of that cocktail that we have tried that we might come back to. It seems to us that the problem with the 'Between the Sheets' is one of indecision and lack of conviction: is it a spirit forward drink or a sour? At least here there is some apparent acceptance that yes, at its best, it's a sour...and a rum based kissing cousin to the Sidecar and Margarita.

It might be a bit too sweet for my taste buds 😀 Perhaps it’s because the triple sec is quite sweet, but the cocktail itself is still enjoyable 👍

It’s good for a variety, but as someone that does quite a few traditional daiquiris and margaritas a year, it just is like in a weird uncanny valley for me. When that triple sec + lime flavor hits, my mouth just expects tequila and agave flavor as well. I recommend trying it at least once, but for me, this won’t be in my rotation.

Very nice. Added some bitters lavender bitters.

I think with Cointreau is too sweet and with Merlet Triple sec, it's dryer and better with

I enjoyed this more than regular daiquiris and it fits me perfectly for warm summer days!

Good, but seems like it needs a little more acid. I'll try it with more lime juice next time.
