limón y sal literally means "lemon and salt", a combination famously paired with tequila! It's a fun and unique phrase that captures the entire message of this song.
Julieta Venegas uses this expression as a metaphor for unconditional love. She's saying she loves her partner with everything, both the sour parts (limón) and the savory parts (sal), accepting all their quirks and flaws.
Have you ever loved someone who drives you a little crazy? That's exactly what Mexican artist Julieta Venegas is singing about in her super fun song, "Limón y Sal."
She starts by listing all the annoying things her partner does. He disappears without explanation, isn't romantic at sunset, and even gets into a "humor extraño / Con cada luna llena al mes" [strange mood / with every full moon of the month]. But even with all these complaints, she decides the good things are more important. The chorus is a beautiful declaration of unconditional love: "Yo te quiero con limón y sal / Yo te quiero tal y como estás" [I love you with lemon and salt / I love you just as you are]. It's a love that accepts the sour with the sweet, embracing her partner's flaws and all. She doesn't need to change a thing about him.
