Safety note: Processing times and altitude adjustments should be confirmed against the current NCHFP page at publication time, since safety tables can be updated or reformatted.
What jar sizes can I use?
This recipe is written for half-pints (8 oz) and pints (16 oz) only. Do not can salsa in quarts with this recipe.
Do I have to peel tomatoes for canned salsa?
For the best texture, yes. Peels tend to get tough and curl up in the jar.
Can I reduce the citrus juice?
No. The bottled lemon or lime juice is doing real safety work here. This salsa is intentionally bright. If you want it softer at serving time, mellow it after opening with avocado, sour cream, a drizzle of olive oil, or a pinch of sugar.
Can I use vinegar instead of bottled lemon or lime juice?
Not in this tested recipe. Some tested salsa recipes use 5% vinegar, but the NCHFP Choice Salsa formulation is specifically built around bottled lemon or lime juice. For safety and consistency, do not replace the bottled juice with vinegar here.
Can I use fresh citrus juice instead of bottled?
For canning, use bottled lemon or lime juice because it has a consistent acidity level. Fresh citrus varies.
Do I have to use onions?
You can use onions, peppers, or a mix. The key is keeping the total amount of chopped onions and/or peppers at 9 cups (measured after chopping). Most people prefer some onion in the mix for classic salsa flavor.
Can I make it hotter?
Yes, but do it the tested way: keep the total amount of chopped onions and/or peppers at 9 cups, and use a mix of mild and hot peppers to suit your heat level. You can also add dried spices like cayenne or chipotle powder. Do not add extra fresh peppers beyond the measured amount.
Can I add corn, black beans, or mango?
Not for shelf-stable canning in this recipe. Those add-ins change density and acidity. Can the salsa as written, then stir extras into a jar after you open it.
My salsa is watery. What happened?
Usually it is extra-juicy tomatoes. Drain chopped tomatoes for 20 to 30 minutes before simmering. Do not press or mash; just let it drip. You can also simmer a few minutes longer before jarring to reduce liquid. Do not thicken with flour, cornstarch, or starches for canning.
My jars did not seal. Can I reprocess them?
Yes, within 24 hours. Your two safe options are:
- Refrigerate unsealed jars and use within 7 to 10 days, or
- Reprocess within 24 hours: reheat the salsa and bring it back to a full boil so it is hot-packed again, use a clean jar, a clean rim, a new lid, and process again for the full time.
