National Mexico
Mexican cultured cream — thinner and more pourable than sour cream, less tangy than crème fraîche, with mild flavour that cools heat without competing with chiles or spices.
Mild, creamy, gently tangy, cool — cooling and binding function, not flavour lead
{"Commercial crema from Mexican dairy brands is standard — Lala or Cacique in diaspora context","Homemade: add 2 tbsp buttermilk per 240ml heavy cream, leave at room temp 12–24 hours","Pour rather than dollop — crema should flow across the dish","Use cold — the temperature contrast against hot chilaquiles, enchiladas, or tacos is intentional","Never heat crema over direct high heat — it breaks to watery fat"}
{"Crema can be infused with chipotle for smoky drizzle","Thin commercial crema slightly with lime juice for brighter finish","Used in rajas con crema, as enchilada topping, inside gorditas"}
{"Substituting full sour cream — too thick and too acidic","Heating crema until it splits","Adding too early in cooking — crema is a finishing element only"}
