You’re in a position to can entire (trimmed) spears or lower them into 1-inch items if that’s extra your jam. You do you, boo.

Wash and clear your jars. It’s not essential to sterilize jars earlier than canning (hurray!) however you need to ensure they’re preheated sufficient to not crack when positioned in sizzling water.

You may put them in a clear dishwasher and run them by way of a fast wash cycle, or place them in a big pan with some water in a low-heat oven (my lowest temp is 170˚F) till you want them. I’ve even simply put sizzling faucet water in them earlier than and left them on the counter.

Wash your lids with sizzling soapy water. Rinse and place them in a clear bowl for now.

If you’re sizzling packing, cook dinner the spears or items in a pot of boiling water for two minutes. If you’re doing a uncooked pack, permit 8 (ish) cups of water to return to a boil in a pot or kettle.

For me, I uncooked pack my asparagus. It’s simpler and sooner; two issues I very a lot favor relating to a canning mission!

Add 3 quarts of water to your stress canner and put it on a burner set to excessive. Ensure there’s a canning rack within the backside of the canner.

Add the asparagus to the jars, gently tapping the jars on the counter to permit the spears (or items) to settle and create more room for added spears (or items).

Utilizing a canning funnel, fastidiously and slowly add the boiling water, leaving 1 inch of headspace.

 Headspace is the space between the highest of the meals and the highest of the jar.

Clear the rim of the jar very nicely with a sizzling damp rag. Any meals particles left on the rim might affect the seal of the lid within the canner. Place a clear lid on the jar. Add a hoop, and tighten to fingertip tight.

Utilizing canning tongs, gently place the jars within the canner. Lock the lid. Quickly, steam will begin coming by way of the vent pipe (I name it the steam chimney).

Enable the steam to move by way of for about 10 minutes. Then put the stress regulator (I name it the chimney cap) on prime. Fairly quickly, the air vent will pop up. That may be a signal that you just’re beginning to construct stress contained in the canner (get excited. That is taking place!).

Processing Time for Asparagus in a Weighted-Gauge Strain Canner

When the dial gauge reaches 11 kilos of stress, scale back the burner temp to medium, and begin your timer. The stress should keep at 11 or (a bit bit) above in the course of the cooking time. You’ll probably want to regulate the temp on the burner a number of occasions relying in your range.

When the time is up, take away the canner from the burner and permit it to take a seat till you hear a particular “click on” of the air vent dropping. Take away the stress regulator and thoroughly take away the lid of the canner (Professional tip: I at all times use oven mitts once I take the lid off as a result of the steam is tremendous sizzling).

Let the jars sit for five minutes within the canner after which fastidiously raise them out with canning tongsProfessional tip: permitting the jars to take a seat within the canner with the lid off may help scale back the siphoning of liquid in your jars.

Professional Ideas/Recipe Notes

  • You may add salt to every jar previous to canning it. Use canning salt and add 1/2 tsp of salt per pint or 1 tsp per quart. Personally, I discover the unsalted model simpler to make use of in recipes as a result of it permits me to regulate the general sodium.
  • Strain canners can usually depart white strains on lids and rings. It’s completely regular and protected. To stop this, add 1/3 cup of white vinegar to the canner earlier than processing.
  • As soon as the jars have sealed, take away the rings. Label and retailer sealed jars in a cool (greatest outcomes are 50-70˚F) darkish place for as much as 12-18 months.
