Citrus salt blends

What it is

Plain salt seasons. Citrus salt seasons and perfumes at the same time, adding a bright, fragrant lift that plain salt simply cannot reach. That added dimension, salt doing two jobs at once, is the whole reason to make it.

Citrus salt blends are the practice of combining salt with dried citrus zest, lemon, lime, orange, or grapefruit, to create a finishing salt that carries both seasoning and aroma. The zest holds the fruit's essential oils, and drying it concentrates that fragrance into the salt. The result is a finishing touch for fish, roasted vegetables, rims of cocktail glasses, and even sweet dishes like shortbread or caramel.

The method is mostly about drying. You zest the fruit, taking only the coloured outer layer and avoiding the bitter white pith, then either mix it fresh into salt and dry the blend in a low oven, or dry the zest first and grind it in. Coarse sea salt or flaky salt suits a finishing blend, while finer salt distributes more evenly. Most people start with lemon salt, the most versatile, and find it disappears fast. The honest trade-off is that fresh zest must be properly dried or the salt clumps and can spoil, but once dry the blend keeps for months. A jar costs almost nothing, using zest that would otherwise be thrown away after juicing.
