Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to make rava dosa [title] Combine the semolina and buttermilk. [step] Whisk together the semolina and buttermilk in small mixing bowl until evenly combined. Cover the bowl and allow the mixture to rest in a warm place for 15 to 30 minutes.

Ending1: [substeps] After the mixture has rested, strain the semolina mixture from the bowl using a sieve. Do not strain the semolina mixture through a colander. Ending2: [substeps] Unlike other types of dosas, rava dosa does not need to ferment for a long period of time. While this mixture rests, you can continue preparing the rest of the ingredients. Ending3: [substeps] You can use cream from a very low-fat yogurt (organic or unsweetened) rather than milk. Cow's milk, unsweetened agave liqueur or unrefined coconut milk or plain milk will all work. Ending4: [substeps] You may place a bottle of semolina or buttermilk inside the ice bath after you've cooled the chilled mixture completely. The semolina and buttermilk product will stimulate the dosa and treat the consumption of bacteria that cause rava by introducing new bacteria from unknown sources.
