Sloe gin: Sloe gin is a British red liqueur made with gin and sloes. Sloes are the fruit (drupe) of Prunus spinosa, a relative of the plum. Sloe gin has an alcohol content between 15 and 30 percent by volume. However, the European Union has established a minimum of 25% ABV for sloe gin to be named as such. Sloe gin is technically a gin-based liqueur, but due to historical prevalence at the time of writing the EU spirit drink regulations, the colloquial name 'sloe gin' was included in the legal definitions and as such is the only gin-based liqueur that can legally be called gin without the liqueur suffix. The traditional way of making sloe gin is to soak the sloes in gin. Most recipes call for the addition of sugar, but this is not required. The drink develops a sufficient sweetness when the fruit is left in the alcohol and is allowed to mature. The addition of sugar is actually likely to inhibit the passage of flavor compounds from the fruit into the spirit, due to a reduction in osmotic pressure; a common criticism of sloe gin is that it is much too sweet.
Amaretto: Amaretto (Italian for "a little bitter") is a sweet Italian liqueur that originated in Saronno. Depending on the brand, it may be made from apricot kernels, bitter almonds, peach stones, or almonds, all of which are natural sources of the benzaldehyde that provides the almond-like flavour of the liqueur. It generally contains 21 to 28 percent alcohol by volume. When served as a beverage, amaretto can be drunk by itself, used as an ingredient to create several popular mixed drinks, or added to coffee. Amaretto is also commonly used in culinary applications.
