In answer to your question about boeber, I wouldn't use ads as a source for the availability of instant mixes. The combination of being primary sources and commercial advertisements with no specific expertise. Common sense said that obviously they wouldn't be advertised if they weren't really manufactured & did, but common sense is not encyclopedic, & neither are online ads.

A secondary source should really be provided saying that you can buy mixes, like a newspaper or magazine article, or a mention in a cookbook, or on the website (or of a mosque or Islamic center (even just in the form of a casual comment that there's no need to make your own because you can buy mixes, or perhaps that there's no need to buy a mix because you can make your own, in the introduction to a recipe for it).

Thank you for drawing my attention to the ads- the recommended procedure is for editors to tag unsourced claims they believe are true (or have no reason to doubt it) and delete those that they consider dubious, so I'm glad you helped me see for myself that they are advertised, which makes me more confident I was right to think that the claim should only be tagged as unsourced, not removed.

Thanks @UrielAcosta, found three sources that might fit. Paywalled, Citizen Journalism, and traditional newspaper (Cape Argus). Will add the latter. --YaguraStation (talk) 22:16, 27 March 2024 (UTC)Reply
Yes, that looks like a reliable source for it. UrielAcosta (talk) 22:37, 27 March 2024 (UTC)Reply
