We're bringin' pickleback
Let’s dive into the details. Our taste buds can detect five primary flavors: sweetness, sourness, saltiness, bitterness, and umami (savory). When we sip whiskey, the bitter receptors at the back of our tongue are activated, but that doesn’t mean the drink lacks other enjoyable notes like caramel and toffee. Additionally, salt can significantly enhance appealing flavors such as sweetness and fruitiness while diminishing unpleasant ones like bitterness, as highlighted in a study published in Nature.
So, when you follow whiskey with a shot of salty pickle juice, it can taste sweeter and less bitter. Furthermore, the heat from the alcohol is intensified by spicy flavors. Since pickle juice is alcohol-free, the burning sensation is soothed by the coldness of the juice. The vinegar’s sourness also serves as an excellent palate cleanser.
This principle is similarly applied to salted rims on margaritas, tequila shots served with lime and salt, and even a sprinkle of salt in espressos. The salt helps to mellow the bitterness of tequila and coffee, creating a more balanced flavor experience on our palate.
Why so bitter?
We all have different taste preferences. Our ability to detect bitterness in food and whether we find it enjoyable is largely influenced by genetics, according to a study led by Pennsylvania State University. Bitterness can vary widely, with examples like grapefruit and coffee, or olives and whiskey. Some individuals may prefer one type of bitterness over another, which explains why some can enjoy whiskey neat while others prefer to chase it to mask the flavor. This is also why pairing a salty chaser can effectively balance our individual perceptions of bitterness.
Sweet pickle juice pairs nicely with sweeter whiskeys, while saltier options complement American whiskeys and even smoky mezcals. Spicy pickle brines are excellent chasers for tequila, reminiscent of a spicy margarita. Additionally, pickle juice serves as a versatile ingredient in cocktails. So, regardless of your taste, consider experimenting with this unique ingredient the next time you’re enjoying shots. You might find yourself singing, "I want my pickleback, pickleback, pickleback..."
