Description
Salsa is one of the most popular condiments in homes today. Because of its popularity, consumers want to prepare and can salsas at home. Home canning of salsa is possible as long as it is prepared and processed according to a recipe tested for safety.
Most salsa recipes are a mixture of low-acid foods, such as onions and peppers, with acid foods, such as tomatoes or fruit. Salsa recipes for canning with a boiling water canner must meet acidity-level requirements to prevent the growth of botulism bacteria. The salsa recipes in this publication have been tested under laboratory conditions to ensure that they contain enough acid to be processed safely in a boiling water canner.
Caution about using original salsa recipes
Because salsas are a mixture of acid and low-acid ingredients, they are an example of an acidified food appropriate for boiling water canning if—and only if—the level of acidity is adequate to prevent production of the botulism toxin. If the mixture has less acidity, it needs to be treated as a low-acid food, which requires additional laboratory testing to develop the processing recommendations for the elimination of botulism risk. To avoid this serious form of foodborne illness, follow the directions carefully for each recipe in this publication. Never can salsas that do not follow these or other research-tested recipes. Freezing is the only safe option for preserving untested or original salsa recipes.
Ingredients
Tomatoes

Use only high-quality tomatoes for canning salsa or any other tomato product. Avoid tomatoes that are overripe or from dead or frost-killed vines. These will result in a poor-quality and potentially unsafe product. Canning is never a good way to use overripe or spoiling tomatoes.
The type of tomato you use affects the quality of your salsa. For example, paste tomatoes, such as Roma, have firmer flesh and produce thicker salsas than large slicing tomatoes. Although both types make good-tasting salsas, slicing tomatoes usually yield a thinner, more watery salsa than paste tomatoes.

Where recipes call for peeled or skinned tomatoes, remove the skin by dipping tomatoes into boiling water for 30–60 seconds or until skins split. Immerse in cold water until cool enough to handle. Slip off skins and remove cores. Remove seeds if desired.
Tomatillos
Tomatillos are also known as Mexican husk tomatoes. They do not need to be peeled or seeded, but the dry outer husk must be removed.
Fruit
Some salsa recipes in this publication contain fruit. Fruits add another dimension of flavor to traditional salsas. When canning fruit salsas you must follow the same safety rules as tomato-based salsas. This includes using a research-tested recipe, selecting fruits in the quantity and condition described, and preparing fruits according to the directions.
Peppers
Choose high-quality peppers. Peppers range from mild to fiery in taste. Very hot peppers are usually small (1–3 inches long); mild peppers are usually bigger (4–10 inches long). Anaheim, ancho, college, Colorado, and Hungarian yellow wax are mild varieties. Choose a mild pepper when the recipe calls for long green chiles.
Caution about working with hot peppers
Wear plastic or rubber gloves when you cut or dice hot peppers because they cause extreme irritation to the skin. Do not touch your face, particularly the area around your eyes, when you are working with hot peppers.

Adjustments to Salsa Recipes
Some ingredients in salsa recipes can be adjusted to suit personal tastes. The changes are primarily limited to ingredient type. It is important not to change the amount of any ingredient, with the exception of dry spices. The table below summarizes the adjustments that can be made to the recipes in this publication without affecting the safety of your canned salsa.
Processing
Filling the Jars
Follow the manufacturer’s directions for preparing lids. Fill hot, clean jars with hot salsa, being careful not to leave any salsa on the rims. Remove any air bubbles and adjust the headspace if needed. Wipe jar rims with a clean, damp paper towel. Put on lids and screw on metal bands.

Using a Boiling Water Canner
- Use a rack to keep jars from touching the canner bottom and to allow heat to reach all sides of the filled jars. Fill the canner half full of water.
- Preheat water to 180°F. Place empty jars into the canner to preheat to help prevent breakage. Jars can also be preheated in a dishwasher. Pretreat lids according to the manufacturer’s directions.
- Fill hot jars according to the recipe instructions. Load filled jars into the canner, keeping them upright at all times.
- Add more boiling water, if needed, to bring water 1–2 inches above jar tops. Avoid pouring water directly on the jars. Place the lid on the canner. (If a pressure canner is used for water-bath canning, leave the cover unfastened and the petcock open to prevent pressure buildup.)
- Turn heat to the highest setting and heat until water reaches a full rolling boil. Once boiling, set a timer for the total minutes required to process the salsa.
- Keep the canner covered and maintain a boil throughout the processing time. The heat setting can be lowered to a gentle boil as long as the boil is maintained for the entire process time. If the water stops boiling at any time during the process, bring it back to a full rolling boil and begin the timing of the process over, from the beginning.
- Add more boiling water if necessary to keep the water level above the jars.
- When the processing time is complete, turn off the heat and remove the canner lid. Wait 5 minutes before removing jars.
- Using a jar lifter, remove the jars, being careful not to tilt them, and place on a towel 1 inch apart. Spoilage could occur if the jars are left in hot water.
Cooling the Jars
Cool the jars on a rack or cloth at room temperature, allowing air to circulate freely around them. Avoid cold drafts or fans blowing on the jars.
Do not retighten screw bands after processing. Retightening hot lids may cut through the gasket and cause seal failure.
Testing for Seal
After cooling 12–24 hours, test each jar for a seal. Jars with flat metal lids are sealed if any of the following apply:
- The lid has popped down in the center.
- The lid does not move when pressed down.
- Tapping the center of the lid with a spoon gives a clear, ringing sound. (This is the least reliable method.)
If a jar is not sealed, refrigerate the contents and use within a few days, or reprocess within 24 hours of the initial processing. When reprocessing, the salsa must first be heated to a boil before packing in hot jars. Wipe the jar rims clean. Use a new lid and process for the full amount of time listed.
Storing
Remove the screw bands so the lids under them do not cause rusting. Wipe jars. Label with the date, contents of the jar, and processing information.
Store jars in a cool, dark place. For best eating quality and nutritive value, use within one year. Heat, freezing temperatures, light, or dampness will decrease the quality and shelf life of canned food.
Before Using
Before opening each jar, examine it for signs of spoilage. Check the lid for tightness and a vacuum seal. Holding the jar at eye level, look for streaks of dried food on the outside of the jar. Inside the jar, look for cloudy canning liquid, rising air bubbles, or any unnatural color. While opening the jar, watch for spurting liquid or cotton-like mold growth on food surfaces or under the lid. Smell for unnatural or off odors. If there is any sign of spoilage, destroy the food. Never taste food from a jar with an unsealed lid or food that shows signs of spoilage.
Disposal of Unsafe Salsa
Unsafe jars of salsa must be discarded carefully to prevent possible illness to you, your family, or your pets. Any salsa that was not prepared according to these or other research-tested recipe should be treated as having produced botulinum toxin and handled in one of two ways:
- If the suspect jars are still sealed, write on the jar Poison: Danger. Do Not Eat. Place the jars in a heavyweight garbage bag. Close and place the bag in a regular trash container or nearby landfill.
- If the suspect jars are unsealed, open, or leaking, they should be detoxified according to the following directions before disposal.
Detoxification Process
Wear rubber or heavy plastic gloves when handling suspect salsa and cleaning up. Remove the jar lids and carefully place the suspect jars (along with the lids) on their sides without splashing in a stock pot, pan, or boiling water canner (8-quart volume or larger). Wash your gloved hands well. Carefully add water until the level is 1 inch above the jars. Put a lid on the pot and heat the water to boiling. Boil for 30 minutes to detoxify the food. Cool and discard the food and lids. Wash the jars and pot.
Spray or wet contaminated surfaces (such as counters and cutting boards) with a household chlorine bleach solution (1 part unscented 5–6% sodium hypochlorite bleach to 5 parts clean room temperature water) and let stand for 30 minutes. Wipe up treated spills with paper towels and put them in a plastic bag before discarding in the trash. Rinse surfaces. Soak metal utensils in a mild chlorine solution (1 teaspoon bleach to 1 quart room temperature water) for 30 minutes. Rinse.
