Chill your Glass (Large) in the Ziploc Bag (Pint Size) for at least 10 minutes before serving. Frosted glasses keep the float colder longer and add a classic diner feel. Tall 16 oz glasses or large mugs work best.

Remove the 3 large scoops 香草冰淇淋 约 1.5 杯总量；选用高质量品牌以获得最佳风味 from the Ziploc Bag (Pint Size) 2–3 minutes before scooping so it's just slightly softened — this helps it cling to the glass and creates a better foam reaction with the soda.

Place 1 large scoop (about ¾ cup) of 3 large scoops 香草冰淇淋 约 1.5 杯总量；选用高质量品牌以获得最佳风味 into each chilled Glass (Large).

Slowly pour the cold 3 cups 根啤酒冰镇，不摇晃 down the side of the Glass (Large) — tilting the glass slightly helps control the foam. Pour about half the 3 cups 根啤酒冰镇，不摇晃 first, pausing to let the foam settle.

Add a second scoop of 3 large scoops 香草冰淇淋 约 1.5 杯总量；选用高质量品牌以获得最佳风味 on top, then slowly pour the remaining 3 cups 根啤酒冰镇，不摇晃 over it. The 3 large scoops 香草冰淇淋 约 1.5 杯总量；选用高质量品牌以获得最佳风味 will rise and create a frothy foam cap — this is the magic of the float!

If desired, top with a swirl of 罐装鲜奶油 and a 2 整个樱桃干. Serve immediately with a long straw and a spoon.
