From the Labs, still working on the vinegar/lime mix, more lime, less distilled?

Prepare beforehand and let steep overnight:
1 part apple cider vinegar
2 parts white wine vinegar
1 part distilled white vinegar
1 part lime juice
Spices (Cayenne, garlic powder, chili powder, black pepper)

Combine 2 parts mix: 1 part tequila
dash of cointreau

Shake with ice, strain into a salt-rimmed martini glass
