The key is in your use of the word "myth" kaiser old chap.
The "fact" is that that "myth" was made up in the 14th century by proponents of the secretive and demonic cult of the creme caramel.
They sought to smear the humble flan case and muddy the waters of the great lakes of Ovenia. Being a secretive bunch of cultists with links throughout both France and North America, it's been incredibly hard for serious researchers to fathom their reasons for such depravity. However, due to the ceaseless work of the former MK Dons franchiser and Kiddies TV presenter, David Oik, we now have conclusive proof that they rejected the often savory content of a true flan and sought to eradicate it from the bakebook. According to Oik, their intent appears to have been to render all baked product sweet. Consigning the quiche, the spinach tartlet and the humble beef wellington to the wastelands, where only the fabled Alexia Joneseii and Yoshi Venturum would munch on their salted goodness. The "fact" that they were prepared to use the good name of the flan in such a twisted agenda betrays their sociopathy. All Ovenia would have been herded into a teeny bakebook where only the likes of the linzertorte and the apple strudel would have survived for our children's tea. The fact that you are here, perpetuating their propaganda shows that you are nowt but a cultural bakxist, bent on completing your hideous Common Pastry plan. I say come out of the woodwork vile plotters. Reveal thy true intent for all to see. We shall not bow to your nonsense nor walk blind into a centralised global oven.
We are free producers and consumers of baked product and we will prevail
