The best approach to equipping your mini liquor cabinet is following the principle that less is more. There are certain items that are most useful. A bar spoon and a tall mixing glass are essential. You can also get a jigger to aid in your measurements ranging from half an ounce to two ounces.
Buy a shaker too, preferably, a Boston shaker. A Boston shaker has two parts with one slightly larger than the other. The shaker is also larger than other shaker types. This allows you to make two drinks at a go. However, you will have to purchase your own strainer.
Fortunately, many supermarkets have basic bar equipment available but you could always shop online as well. Alternatively, if you don’t have the budget for these items, you may tap into what you already have in your kitchen.
For instance, a measuring cup could double up as a jigger, slotted spoons as strainers, and metal water bottles or mason jars as shakers. Ultimately, the booze is most important. Everything else is expendable.
