Don't know if you would need more equipment....Some fancy decanters maybe...but you can pick those up at the Goodwill, junk stores and 'Sally-Ann' [Salvation Army]....some tiny bottles to give as gifts.
You can also 'flame' these cordials and impress your Friends with a flaming dessert.
For the actual Liquor types you will have to buy the little bottles of mix...plus get some of that Glycerin Finishing Formula...it gives the liquor it's 'legs'.
Some of them you can't make from 'scratch'...like..Drambuie, Irish Creme...and... Grande Marnier and some others...they have the recipes how to make it with the little mixes.
As for the Grand Marnier and some of the others I have seen recipes from scratch on the Web...you can do a search....
Some are made with Vodka, some with Brandy and some with Rum.
BTW...there is a recipe for the RUMTOPF that Martina tempted us with last Christmas..Think she made hers throughout the summer, adding fresh fruits as they became available and added Rum to cover...This recipe they just buy a bunch of fruits [not Blackberries or apples] add 1 cup of sugar for every 3 cups of fruit...cover with Rum and wait 3 weeks...serve over ice cream, custard or cake.
Have only made the Raspberry Cordial once...girlfriends make it now from my berries and I get some from them. One friend has made Cordial with some native type Nanking Cherries, it was very good...think you are limited only to your imagination and fruits avaible...
This little book Kitchen Cordials is fun, there is a bigger book called Cordials From the Kitchen, Making Liqueurs for Gifts and others...Ask Santa to bring you one....
