Natilla and crema (Central American fermented cream)natilla
Natilla is cream soured by suitable microbes until its pH drops, with or without thickening; the regional regulation RTCA 67.04.71:14 also uses the name for cream soured with added acids. It must hold at least 10 % milk fat, or 45 % for natilla doble.

RTCA 67.04.71:14 is a Central American technical regulation that corresponds to the Codex standard for creams, CODEX STAN 288-1976. Its bibliography lists earlier national texts, including Costa Rica's RTCR 412:2008 for cream and sour and fermented cream (natilla).
