Parametric recipes are great. The central ingredient is quantity 1 and everything else is a ratio by weight. You then scale it to your needs. So an equilibrium brine would be.
1 meat 1 water 0.03 salt Brine for 1 day per 2 inch of thickest section.
They don’t work for everything. So when baking a loaf of bread time and temp are spefic to loaf size. It still works for a batch of bread dough however.
This also helps you think in ratios which help general recipe construction. Once you know what flour to egg radio you like for your bread you can alter recipes to your preference.
As far as the witcher and time travel kind of. At some point in the future there was a disaster and Earth was destroyed. However some humans and lots of monsters from alternate realities ended up in the world of the Witcher. Elves and dwarves were the original inhabitants.
Humans used a mix of genetic engineering they had and magic taught to them by the elves to make the Witchers. The Witchers helped solve the massive monster problem and the world ended up with humans mostly on top.
Witchers age very slowly and if not killed can live a very long time. Powerful magic users are basically the same. So the stories from session 1 are spread over about 80 years with some long lived characters.
The first book that season 1 is primarily based on is also different from the other books. It’s a bunch of short stories that are based on classic stories. So there is Sleeping Beauty, Snow White, Beauty and the Beast, etc.
