Milky Drink Yakult
See above for the note on 'milky drink.'How to Make a Milky Drink
'Milky drink' is 'nyuusankininryou' which is actually a fermented milk drink, like Yakult or Calpico. The kanji for this is 乳酸菌飲料, however, compare this to the kanji in the image, which is 乳酸銀飲料. The middle character is 'gin' for silver instead of 'kin' from the original word. I guess this is a pun on her name, Suigintou.
