Yeah this basically, France won't need the Caribbean like OTL because they already have an agricultural gold mine in Brazil, plus with the English and Swedish arriving in the place, they have less incentive to go there, especially because their colony will have a more diversified economy.OTL Brazil already had some Jewish influence, specially in the Northeast under the Dutch, so i definitely can see them having a big community. Although, i imagine they would blend into the melting pot rather than being "isolated" like in the USA.
A Brazil that resembles Southern France is pretty cool, thanks for the insight on the cuisine. I can see something like Coffee cakes being popular in France as well.
Does not make much sense tbh, the Caribbean got really important after the Dutch stole the Northeast from the Portuguese and subsequently lost it, after that suger cane spread; if i remember my classes correctly originally the Portuguese were quite protective of their product.
And Jews will have even more influence in Brazil TTL given they're not being discriminated against and will help in getting business off the ground in the colony, especially when it comes to slave importing alongside sugar, tobacco and sugar exporting, not to mention the fact many of them are of "gentle" professions like doctors, lawyers apothecaries and such will help a lot with the development of the colony not only in the people there but also into getting stuff like the judicial and medical systems in the colony be much more developed which will definitely help out the administration and make more people come given there will be a shift perception from "heathen hellhole" to "barely civilized outpost in the end of the world"
