There is no liqourice (or licorice) emoji. There is a chocolate bar emoji.
Creating a liquorice emoji may seem simple, but it immediately runs into cross-cultural challenges, specifically what is liquorice and what does it look like.
In Scandinavia and northern Europe, liquorice is salty. This is called salmiak liquorice, you also often see the the term zout (salt) as in double (DZ) or triple salt liquorice.
See Wikipedia – Salty liquorice and the New York Times – The Saltier the Licorice, the Happier the Country. Just Look at Finland.
Finnish sweet ‘salmiakki’ is liquorice spiced up with Ammonium chloride. It is something Finns can’t live without.
Unfortunately it doesn’t have great characteristics, which is to say if you didn’t already know what it is supposed to represent (a woman eating diamond liquorice) then you would have a hard time figuring it out.
The ideal representation would be a simple black diamond, which could be reused for other purposes as well. Except the emoji set has no black diamond. There’s a set of card suit emojis, so of course the emoji is a red diamond. There are also, inexplicably, blue and orange diamonds in two sizes (I guess these must have some culture-specific meaning). The only place you can get a black diamond emoji is from Mozilla, who have misread the ridiculously confusing specification. The specification says that “black” means filled, not, you know, black.
When describing pre-emoji Unicode symbols, black in a character name refers to the symbol being solid/filled in.
So the emoji “black diamond suit” is actually a filled red diamond. Except from Mozilla. In the Mozilla emoji set on Emojipedia the diamond is black, and in the Mozilla emoji set on Github the large diamond is red but the smaller diamond on hover is black.
So for salty liquorice all that is needed is an actual black diamond emoji.
But that doesn’t represent liquorice globally. In the US and Canada, probably the closest would be a black Twizzler, which isn’t even really liquorice. Plus which particularly in the US, it tends actually to be a red Twizzler, which they call red vines (I only know this from Gilmore Girls). This red candy is popular enough (or maybe recognizable on screen enough) to have appeared being enjoyed by characters in US TV shows, including The Flash and Agents of SHIELD. Since “red” liquorice doesn’t actually exist, it’s not actually liquorice at all.
In the UK I don’t know, maybe a Pontefract cake? (Which is not actually a cake, it’s more like a coin-shaped candy. I only know about these because of a BBC Radio 4 Extra cake series – episode Pontefract cake.) And in France probably a Zan tablet (now Haribo Zan), which is yet another different liquorice experience.
Basically there’s a good case for the salty liquorice black diamond emoji, but I don’t think there’s an emoji that would recognizably represent liquorice globally.
As a sidebar, a much better emoji approach to shapes would mirror the one used for skin tones, which is to say, just have the hollow and filled shapes and then add markup for colour. And maybe markup for size. With four emoji codes already for blue and orange diamonds, it doesn’t make sense to keep adding two more codes for every new colour.
