Lemon Juice

Lemon Juice being rich in Vitamin C is an excellent remedy for sore throat and aids in digestion and controls blood sugar, and also promoted weight loss. It is used for various culinary and non-culinary purposes all over the world. Lemon juice is known to reduce or even reverse the effects of excessive alcohol consumption and intoxication.
In drink mixing, fresh lemon juice brings a tangy zing to so many classic drinks and in fact, it's the most used ingredient in drink mixing other than the liquors of course.

Grenadine

Grenadine is a common non-alcoholic pomegranate syrup with a characteristic deep red colour. It is a very popular cocktail ingredient, used for its pomegranate flavour and more for its ability to add a reddish to pink tint to a cocktail.

The name Grenadine originates from the French for pomegranate, which is grenade.

Grenadine is not subjected to regulations like alcoholic beverages are, and there are no region specific formulae any more, and thus manufacturers often replace pomegranate with blackcurrant juice and other fruit juices while retaining the same flavour profile.

Many producers now use artificial ingredients like high fructose corn syrup, water, citric acid, sodium citrate, sodium benzoate and food grade red colour along with natural and artificial flavours.

Orange Juice

Orange Juice is an excellent source of Vitamin C, one cup contains twice the daily recommended value. Vitamin C supports the immune system and helps fighting the common cold. The folate in Orange juice supports healthy fetal development. It is low calory and thus is already a qualified alternative to cola fizz in your cocktail if you want to keep your drinks acceptably healthy.

Orange Juice being citrus and naturally sweet and sour, it literally goes with almost any liquor, and of course Vodka being neutral, the best known pairing is with Vodka. But goes well with Dark Rum too, and you get the Planter's Punch, mix it with Champagne and you have made a mimosa, or with tequila to make a tequila sunrise.

Rum

Rum is a liqour that originated in the West indies and is made by fermenting then distilling sugarcane molasses or sugarcane juice. The distillate is usually a clear liquid and is then aged in oak barrels.

Most Rums are produced in the Caribbeans and American countries, but are now produced in other sugar producing countries like PHilippines and Taiwan.

The first recorded mention of Rum comes from Barbados, in about 1650. They were originally called "kill-devil" or "rumbullion" and later on, simply Rum.

Sugar

Brown Sugar is a sucrose sugar with a distinctive brown colour from the presence of molasses, it is a partially refined or unrefined sugar containing sugar crystals and residual molasses giving it a distinctive taste and flavour of crystallised molasses or toffee. The taste of dark brown sugar is described as a caramel taste with a deep molasses flavour.
Brown sugar is used in cocktails where a caramel candy or toffee flavour is expected.

Caster Sugar is finely ground granulated sugar. It is not as fine a powdered confectioners' sugar and has a little grit to it. It is somewhere between confectioners' sugar and granulated sugar, and melts in mouth with a mild spicy feel to the tongue

Vanilla Sugar is the regular granulated sugar infused with vanilla flavour, by using vanilla pods and seeds to flavour the sugar. A home made alternative is to use vanilla sticks or pods in a jar of sugar and leave it sealed for 4 weeks to allow the vanilla flavour to infuse. Or to use granulated sugar and vanilla extract and blend in a mixer, although this ends up in powdered sugar.

Triple Sec

Triple-Sec is an Orange flavoured liqueur from France. It is made by macerating sun dried orange peel in alcohol for a day or more before a three step distillation. Triple Sec has a 15% to 40% ABV.

The Triple Sec name refers to the process of distillation. Sec in French means dry or distilled and triple refers to the triple distillation process.

It's been a popular liqueur for more than 150 years, the Dutch East India Company created orange liqueurs by steeping orange peels in alcohol from the island of Curaçao and called it Curaçao liquor, and unlike Triple Sec, the Dutch added spices and herbs to the orange and Curaçao comes in a variety of colours such as clear, orange or blue. Blue Curaçao being the most used of them, in cocktails. Triple Sec is made from neutral spirits and the Orange peel used is harvested from oranges that have the skin still green, so that the essential oils are still in the skin and has not been absorbed into the flesh. This gives Triple Sec the intense flavour.

Water

Water might seem like one ubiquitous ingredient in any alcoholic beverage, and to have no specific purpose other than dilute the alcohol, to prevent irritation and burn, it has more purpose to its presence than it seems.
Water breaks the alcohol molecules and attaches to them and releases the esters that holds the secret to the aroma into the drink and to the nose. Temperature of water is important and although almost all cocktails are served chilled, be sure to understand the role water plays in a drink. Another factor is the quality of water, if you are serious about your cocktail, be sure to use the best neutral tap water or preferably bottled spring water if possible.
