When you matched cocktails to BLs the other day, it reminded me of all the colorful cocktails in Thai shows. Do you know what they are--especially the Windex-Blue drink? They can't all be drinking Blue Curacao, can they?
They might be using blue sala syrup. Or they might be using butterfly pea syrup (nom anchan AKA นมอัญชัน).
Most BL watchers are familiar with the red sala syrup, that's what turns pink milk pink. It's meant to taste like palm fruit (it doesn't much).
But there are actually 3 popular flavors: dang (red); kieow (green) which is cream soda flavor; and (mali) or jasmine which is clear/slightly yellow. There are a lot more, these are basically like italian soda flavorings they just put them into milk.
I think there is also a blue version.
King in the scene where he meets Ram with the others at the cafe, and learns Ram's name, is drinking either blue or green milk. I can't remember witch and I'm too lazy to investigate.
Butterfly Pea is a common colorant in Thai food, it's in a lot of the deserts in Until We Meet Again
It turns Chor-Muang ขนมช่อม่วง blue/purple. Also Bulan Dan Mek ขนมบุหลันดั้นเมฆ. Pandan is also used as a colorant for green things. Unlike butterfly pea it does as quite a bit of a flavor (a sort of grassy fragrant vanilla).
But honestly?
Blue Curacao is cheep and easy and widely available, so it's probably that.
