In a small saucepan, bring the tequila to a simmer.
Remove from the heat, add the currants and let soak for 10 minutes; drain. In a medium saucepan of boiling salted water, blanch the chayotes for 1 minute; drain and let cool.
In a medium bowl, toss the chayote, tequila-soaked currants, tomatoes, onion, garlic, jalapeos and cilantro. Season the salsa liberally with salt and pepper and serve.
Make Ahead: The unseasoned salsa can be refrigerated for up to 1 day. Bring the salsa to room temperature and season just before serving.
