Given the task definition, example input & output, solve the new input case.
In this task, you have to identify the named entities (NER) which are the ingredients required given its directions. Named entities are the names of the items without their quantity.
Example: Preheat oven to 375 degrees., Boil syrup, sugar and shortening over medium heat, stirring constantly., Remove from heat., Gradually stir in flour and nuts., Drop by teaspoonfuls about 3 inches apart on lightly greased cookie sheet., Bake 5 to 6 min., Remove from oven and let stand 5 min, before removing from sheet., May be rolled into cylindrical shape while still hot., If cooled too much, return to oven for a minute., Yield: 4 dozen cookies.
Output: flour, nuts, corn syrup, shortening, brown sugar
This is a good example, as we see the NER is generated correctly from the directions.

New input case for you: Preheat oven to 325 degrees and set aside an ungreased 10-inch tube pan., Place the egg whites and cream of tartar in a medium mixing bowl and beat with an electric mixer on high until stiff peaks form, about 2-3 minutes., Place the cake mix, egg yolks, water, oil, coffee powder, and vanilla in a mixing bowl and blend on low for 1 minute. Stop the machine to scrap down the sides with a rubber spatula then increase mixing speed to medium and beat for 2 more minutes, continuing to scrap the sides of the bowl as needed. Turn the beaten egg whites on top of the batter and with a rubber spatula fold the whites in to the batter until the mixture is combined but still light. Pour the batter into the prepared pan, smoothing out the top and place the pan in the oven., Bake the cake until it springs back when pressed with your finger and a toothpick inserted in the center comes out clean and without batter, about 48 to 52 minutes. Remove the pan from the oven and immediately turn it upside down over the neck of a glass bottle. Run a long, sharp knife around the edge of the cake and invert it onto a serving platter so it is right side up.
Output:
egg whites, cream of tartar, cake mix, egg yolks, water, vegetable oil, coffee powder, vanilla
