Greetings my friend! We totally agree with you that each of the learning challenges must be universal and not have any type of limitations so that many users can join either to learn or reinforce their knowledge. However, we think that the challenge of this week has Gelatin as its star ingredient, which is a universal ingredient that even has its World Day which is celebrated on April 2nd of each year. From what you mention, is this ingredient not available in your country? If so, we apologize because we consider that this product could be obtained anywhere in the world.
