This recipe has been on my wishlist for awhile, which I’m so glad I finally got to make this, as I used Sunshine & Sons gin which adds notes of pomegranate, lavender and pink rose, which works really well in a Singapore Sling

Retried both this and the raffles version side by side, tho cut the pineapple to 90 ml for the raffles version. I think it should be remembered that this was originally a tropical climate drink, so large amounts of fruit juice for rehydration made sense, perhaps less so for modern air conditioned lifestyles. I think they are both great drinks in their contexts.

I made this with a locally produced chilli infused gin and it worked really well

Tried this side by side with the Raffles Formula (https://www.diffordsguide.com/cocktails/recipe/1825/singapore-sling-raffles-formula) - minus the soda:
The Dale DeGroff Sling is less sweet and more tart.
Importantly, imho, it lacks the pineapple note and mouthfeel (amazing foam) of the Raffles/IBA formula, but I guess that's down to preference.

Fikk denne i Fredericia. Må prøves

Haven’t invested in a bottle of Heering yet, so improvised with 1/4 oz of Luxardo Maraschino and 1/4 oz of Luxardo cherry syrup. Still delicious!

Ooops, just added double the triple sec (Combier), so I substituted Luxardo Apricot for the cherry, reduced to 10ml; and 7.5 ml Hayman's Sloe Gin instead of grenadine. Also kind'a leaned in on the gin. Delicious!

Being from the country where this is from, and having had it in the Raffles Bar itself - my first alcoholic drink after being allowed to drink legally, this was in 1986 - I can honestly say this formula is the closest to my memory of the drink.
