Small correction: the vitamin in question is the B₃ (niacin), not the B₁₂ (cobalamine) like I previously said. (I just checked it.)
Mexican and Tex-Mex food is something of a staple around here, so I’m surprised to hear that cooks use lime with maize. I don’t think I’ve ever seen it in any recipe, but maybe that’s kind of a Gringo issue.
Odds are you already ate it, either as masa harina (the one used for tacos) or as hominy: the maize is cooked in limewater, then washed, then further prepared. It’s just that nowadays odds are you already buy it after it was slaked in lime.
Nowadays it isn’t a big deal, because food sources got extremely varied, but for the Aztecs and neighbouring peoples it was a way to prevent pellagra.
Oh wow, interesting. I’ll have to see if the Brasilian restaurant nearby is still around. I’ve been quite remiss in not checking them out, sadly. :/
In case you’re looking for it, the local name is “doce de abóbora”. It should look like this:

Sometimes cut into fancy shapes, like hearts or similar. Or simple cubes, specially if homemade. It can be made with either pumpkin proper (abóbora moranga) or butternut squash (abóbora menina).
(Key) Limes are of course integral to making ceviche & tiradito. Is there a counterpart in Brasil?
None as far as I know. Tiradito is almost unknown; ceviche is somewhat well known but associated with Peru, much like sashimi is associated with Japan. (Kind of weird how the Japanese community in Brazil managed to spread yakisoba and gyoza [aka pastel], but sashimi is still seen as “exotic”.)
In fact the only two dishes I recall using raw meats use beef instead:
- carne de onça (lit. “jaguar meat”, but more like “meat eaten like a jaguar would”) — it’s German Mett, but with beef instead of pork. Still to be served over rye bread, with onion, and some raw yolk.
- quibe cru (lit. “raw kibbeh”) — it’s the kibbeh nayyeh the Levantines eat, brought by immigrants. (I’m not even sure how well known it is; I eat it often because the only person who got enough patience to teach my mum cooking 101 was a Lebanese granny.)






Incidentally I did share the recipe for those some time ago, if you want to give it a try.
Sometimes I do share recipes (like the above) but it’s all spread across Lemmy/PieFed, not in a specific community.
