"Il n'y a rien de mieux pour faire les meilleures tartes"

Question

I'm wondering why mieux is used instead of meilleur when referring to organic ingredients in the statement, "There is nothing better to make the best tarts"?

As per the lesson that's linked on that page, I thought it would fall under "qualifying something as good/better/the best at what it does, i.e. efficient/practical, or good/better/the best in taste (food)".

Is it instead considered to be "making a general statement with être about something or someone being fine/OK/better/the best" ? It would be helpful if the lesson included "Il y a" in addition to être if so.

Thanks in advance for any clarification!

Bonjour Elysia,
Here, "there is nothing better to..." is a general statement which you could replace with "It's better to..." and in French, you would say "C'est mieux pour ...". Therefore, using the French adverb "mieux" is correct here.
The lesson states that: 
In French, you'll use the adverb bien and its comparative mieux when:
making a general statement with être about something or someone being fine/OK/better/the best
 
I hope this is helpful.
Bonne journée !
