The rules where you could use products of any brand and not just Arla, and the winner would be decided by popular vote. Rather quickly a vegan pastry shop got first place by a really high margin to second place. And just like that they got disqualified because the rules changed so now you had to use Arlas products..
Except the would be winner was disqualified, not for being vegan, but for using an ingredient, "kokum butter", which has not been categorized by authorities as Generally Recognized as Safe (GRAS) yet.
Kokum, for those wondering, is in the mangosteen family (Garcinia) and the fruit is often used as a souring agent in South Asian cooking. The fat from the seed, like cocoa butter, is used in cosmetics but is also edible and has culinary applications.
I get that "rules are rules" and an ingredient was used that wasn't approved... But based on the activities like having a co-winner, leading up to the disqualification makes me think it's not the fact that it's vegan that's a problem, it's the threat and validation that a plant-based product could be great or better than its dairy equivalent.
