A snowball is a mixture of advocaat and a carbonated lemonade in approximately equal parts. It may have other ingredients, to taste.^[1]

It typically contains a squeeze of fresh lime juice, which is shaken with the advocaat before pouring into a glass and topping up with lemonade.^[2]

In the United Kingdom, it is often sold in both pubs and supermarkets in small bottles of approximately 113 millilitres (4.0 imp fl oz; 3.8 US fl oz) or 180 millilitres (6.3 imp fl oz; 6.1 US fl oz) (known in the pub trade as "splits") and is usually drunk as a "winter warmer".
