The cola is typically mixed with another ingredient, such as soy sauce, barbecue sauce or ketchup.  It can be prepared with regular or diet cola.  As the dish cooks, the sauce reduces, accentuating the cola flavor and creating a glaze in the process.  It is sometimes prepared as a chicken wing dish.  It can have a sticky texture, depending on how it is prepared.  Cola chicken has been described as a dish that has flavor elements of sweet and sour, and the cola has been described as imparting a rich flavor in the chicken meat.

Fentimans Curiosity Cola: Fentimans Curiosity Cola is a botanically brewed carbonated cola soft drink, a product of British brewery Fentimans.  The brewing process used gives the drink an alcohol content of up to 0.5%, but this small amount still allows it to be sold as a soft drink.  It is sold in 275ml and 750ml glass bottles.  In Europe and North America it is legal to sell the cola to minors.

Afri-Cola: Afri-Cola is a cola soft drink produced in Germany.  The trademark Afri-Cola was registered in 1931 by the company F. Blumhoffer Nachfolger GmbH.  The same company also produced Bluna, an orange soft drink.  Today the brand belongs to the Mineralbrunnen Überkingen-Teinach AG.  Afri-Cola was once one of the most popular cola brands in Germany, but has considerably lost market share since the 1960s.

J2O: JO is a still soft drink made from fruit juices.  It is manufactured by Britvic and sold in the United Kingdom and Ireland.

The name ‘JO’ is a pun on the chemical formula for water, HO, chosen due to the drink's 50% fruit juice content.  The first flavours available were Orange & Passion fruit, Apple & Mango and Apple & Melon, but the range has progressively grown since.

Jolly Cola: Jolly Cola is an original Danish soft drink dating back to 1959.

This was extraordinary, as Denmark is one of a few countries in the world, where another cola than the original Coca-Cola has had a larger market share.

Cavan Cola: Cavan Cola was a brand of soft drink produced by Cavan Mineral Water Ltd. in the town of Cavan, Ireland.  It was introduced in 1958, and was sold in 250ml bottles in shops in counties Cavan, Monaghan, Sligo, Leitrim, Louth and Meath.  The product proved so popular there that it went national in the early 1990s.  In 1993, the still family-run Cavan Mineral Water Ltd. was taken over by Finches, who began phasing out Cavan Cola.  By 2001, Cavan Cola had disappeared from most shops, even in County Cavan.  In recent times, the parent group has been the subject of a number of rival bids.  According to many, including Ciaran Cunningham, Cavan Cola was the greatest drink ever produced.

Piscola: Piscola or Combinado Nacional (national mix) is a highball cocktail, made of pisco and most commonly a cola drink, that is popular in Chile.
