Using a fine grater or zester, carefully zest 1 to 2 washed limes. Be sure to only zest the green part of the skin, avoiding the white pith, which can be bitter.
2 Limes zested
In a small bowl, combine the kosher salt and the lime zest. Use your fingers to mix them together, gently rubbing the zest into the salt to release the lime oils.
2 Tablespoons kosher salt
Spread the mixture in a thin layer on a lined baking sheet. Bake at 100°C (220°F) for 1 hour, or until the zest is completely dry.
Once dry, transfer the lime margarita salt to an airtight container for storage, or use it right away to rim your margarita glasses!
Notes
Tips and Tricks
For extra flavor: You can add a pinch of sugar to the salt mixture for a sweet-and-salty contrast.
Make it spicier: Add a dash of chili powder for a spicy kick.
Storage: Keep the salt in an airtight container for up to 1 week to preserve freshness.
Use it beyond margaritas: This salt works great on the rim of other citrusy cocktails or sprinkled over grilled seafood and vegetables.
