Not safely. Many rice based vinegars are not 5% acidity and that is what is required as a minimum. Also, even if it says it is 5%, rice vinegar does not retain its acid levels during long term storage as well as either cider or white.

In any salsa recipe the vinegar is the primary safety factor so it is probably the one ingredient you shouldn't mess with. ;)

However, you can substitute bottled (never fresh) lemon or lime juice for the vinegar as they both are more acidic than vinegar (2x as acidic) and many find the taste to be more "salsa-like". Simply sub the same amount of either juice for the amount of vinegar called for in the recipe.

Bottled lemon or lime juice can always be safely subbed for vinegar but you cannot substitute vinegar for lemon or lime juice.

I make all my salsa with lemon or lime juice. Very yummy.

Presume you used bottled lemon and lime juice?
