ONION lattes are set to crop up in coffee shops as the odd blend has taken root on social media.
TikTokers have been experimenting with unusual ingredients and recipes.
One of the most popular is the onion latte — which has racked up 20 million views this year.
Bosses at Reviva Coffee say shops will follow the trend which involves adding cut up or dried onions, shallots or spring onions to a latte.
Most have it chilled as an onion ice latte, but some have it heated up for a warm and spicy treat.
But the most popular new trend is a “cracking” latte — where chocolate is spread on the inside of a plastic cup and hardened in the fridge.
When a coffee is poured inside, the cup is squeezed so the chocolate shell cracks.
Clips have gathered 50 million TikTok views.
Kinder Bueno lattes attracted 11 million users, caramel “cloud” latte videos were watched five million times and lemon coffee recipe clips had four million views.
A Reviva Coffee spokesman said: “Onion coffee shows a bold year ahead for recipe experimentation, blurring lines between bizarre and downright delicious.”
