The right way to can asparagus

As your elder millennial grandma, I’m going to stroll you thru the method right here with images, and also you’ll additionally discover a detailed and printable tutorial on the backside of this put up.

For canning asparagus, you’re going to decide on recent and tender spears. Take away the woody ends and trim any of the little scales that develop on the stalks.

You’re in a position to can entire (trimmed) spears or reduce 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 be sure that they’re preheated sufficient to not crack when positioned in scorching water.

You may put them in a clear dishwasher and run them via 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 scorching faucet water in them earlier than and left them on the counter.

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

If you’re scorching 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 come back to a boil in a pot or kettle.

For me, I uncooked pack my asparagus. It’s simpler and quicker; two issues I very a lot want on the subject of a canning mission!

Add 3 quarts of water to your strain canner and put it on a burner set to excessive. Be certain 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, rigorously and slowly add the boiling water, leaving 1 inch of headspace.

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

Clear the rim of the jar very effectively with a scorching 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 via the vent pipe (I name it the steam chimney).

Permit the steam to move via for about 10 minutes. Then put the strain regulator (I name it the chimney cap) on high. Fairly quickly, the air vent will pop up. That may be a signal that you just’re beginning to construct strain contained in the canner (get excited. That is occurring!). See the 4 picture grid under for a visible of this course of step-by-step.

Processing Time for Asparagus in a Weighted-Gauge Stress Canner

When the dial gauge reaches 11 kilos of strain, cut back the burner temp to medium, and begin your timer. The strain should keep at 11 or (a bit of bit) above throughout the cooking time. You’ll probably want to regulate the temp on the burner a couple of instances 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 strain regulator and punctiliously take away the lid of the canner (Professional tip: I at all times use oven mitts after I take the lid off as a result of the steam is tremendous scorching).

Let the jars sit for five minutes within the canner after which rigorously raise them out with canning tongsProfessional tip: permitting the jars to take a seat within the canner with the lid off will help cut back the siphoning of liquid in your jars. Siphoning is when liquid seeps out from underneath the lids and reduces the general quantity of liquid within the jar.

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.
  • Stress canners can typically go away white strains on lids and rings. It’s completely regular and protected. To forestall 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.
