To speed up the ripening process, you could set them on a sunlit windowsill or you could keep them at room temperature in a bowl with a ripe tomato or banana or in a closed brown paper bag for a few days.
Lai zaļi tomāti ātrāk nogatavotos, tos var ielikt traukā kopā ar gatavu tomātu vai banānu un dažas dienas paturēt istabas temperatūrā. Tomātus var gatavināt arī brūnā papīra turzā, kam aizlocīts gals, vai uz saulainas palodzes.
