Instructions

Start boiling 4 quarts of water.
-
Prepare asparagus by washing, snapping off tough ends, and ensuring spears are no longer than 6 inches.
-
Pack asparagus tightly into clean quart jars, adding 1 teaspoon of salt to each if desired.
-
Pour the boiling water over the asparagus, ensuring spears are fully immersed with 1 inch of headspace, then secure with seals and rings.
-
Pressure can jars at 10 pounds pressure for 40 minutes for quart jars, or 30 minutes for pint jars with shorter spears; adjust for high altitude.
-
Allow the pressure canner to cool completely and pressure to drop to zero before opening.

Remove jars, cool on a towel, then remove or loosen rings and test lids for a proper seal.
-
Label sealed jars and store them away from direct light and heat.
