Y-Peeler vs Channel Knife
A wide twist against a thin spiral: aroma against appearance.
Which should you use?
For aroma, a Y-shaped peeler wins. It takes a wide strip of peel with little pith, so there is plenty of oil to express over the drink. A channel knife cuts a thin groove for long, decorative spirals, like the Horse's Neck's. Those look good and give far less oil. Start with a sharp peeler; add a channel knife if you want the spiral.
| Dimension | Y-peeler | Channel knife |
|---|---|---|
| Strip | Wide, flat swathe | Thin, round groove |
| Oil to express | Plenty | Little |
| Pith taken | Little, if sharp | Very little |
| Best for | Expressed twists on Martinis, Old Fashioneds, Negronis | Long spirals and decorative curls |
Using one in place of the other
A peeled strip can be cut into a thin twist with a knife; a channel-knife strip cannot be made wide. That is why the peeler is the more useful tool.
In the recipes on this site
Any recipe that asks for an expressed twist is better served by a peeler; recipes with a long spiral garnish need the channel knife or a careful knife.
