Quantities of squash needed

Numbers are gauge guidelines.

On average, every bit a very rough guideline, expect to need about one kg (2 ¼ lbs) of fresh, unpeeled squash per 1 litre (US quart) jar of canned squash.

7 kg (16 lb) of squash = seven litres (US quarts) canned squash
4.5 kg (x lbs ) of squash = 9 x ½ litres (US pints) canned squash

A drained litre (US quart) jar will hold 750 m (ane.6 lbs) 0f blanched squash cubes.

A drained ½ litre (US pint) jar will hold 350 m (12 oz) of blanched squash cubes.

Don't waste product the seeds!

You lot can "double dip" and get an extra bonus product out of your work too canned squash — namely, roasted squash seeds.

Roasted squash seeds are very adept eating.

To make them: wash the seeds. You don't need to go all the footling bits of squash off the seed — in fact, they are tastier with the little pieces of squash on them.

Toss in a fleck of oil of your choice, and roast in a slow oven 125 C (250 F) for 10 to 15 minutes, tossing with a spatula one-half-way through.

Shop in sealed container in the fridge. Good for a few weeks. (Or, freeze.)

You can season as desired with a nice common salt substitute, some parmesan cheese, some chili powder, etc.

Background overview

To can pumpkin or wintertime squash, you lot accept to peel and seed them, cube, blanch lightly, then pack in jars and pressure level tin can (never water bathroom.) Penn Land Extension says,

… cut the peeled product into 1 inch (3 cm) cubes and add them to boiling h2o; cook them for 2 minutes and then pack the hot cubes into hot jars; fill the jars with boiling hot cooking liquid. Allow 1 inch (3 cm) headspace. Process at 11 pounds force per unit area in a dial judge pressure canner or 10 pounds pressure in a weighted gauge pressure canner. Procedure pints (½ litres) for 55 minutes and quarts (i litres) for 90 minutes." ^[ane] Penn State Extension. Pumpkin and Winter Squash. October 15 2012. Accessed Jan 2015.

The cubes let water and heat to flow evenly through the jar to ensure that no cold spots remain unsterilized. Mash after opening and draining.

Knowing that, you won't be surprised that the most pop multifariousness for canning is butternut squash, specifically winter squash, equally information technology doesn't have the ridges that most other squashes do and is really like shooting fish in a barrel to pare. It also has a minor seed cavity that is piece of cake to clean.

You can can whatsoever variety of winter squash, though, if yous're willing to put the peeling work into it!

Pumpkin and Winter Squash canning don'ts

No mashing

Don't try to home can pumpkin or winter squash mashed or puréed, it's not safe.

Just about everyone going into this for the commencement time goes: await, can't I merely broil the squash, scrape it off the skin, and and then tin can the squash flesh that way? It would be so much easier….

You cannot, considering it has been proven in labs that at that place are very real density issues with mashed squash (or squished squash) that prevent the required heat distribution to fully penetrate throughout the jars in dwelling house canning.

The cubes allow water and heat to catamenia more evenly through the jar.

Penn Country Extension says,

Practise non can mashed or pureed pumpkin because the purée is besides dense for acceptable oestrus to penetrate to the middle of the jar during processing." ^[ii] Ibid.

Just go ahead and mash information technology all you like when yous open up the jar! Just bleed the water off first (tip! freeze that tuckered-off water for wonderful soup stock.)

If you want to store it mashed, you must freeze it.

No canning of spaghetti squash

Annotation that spaghetti squash is explicitly recommended against equally the exception: all other winter squashes are fine to can.

Penn Country Extension says,

"Spaghetti squash is non suitable for canning." ^[3] Ibid.

The Academy of Georgia Extension Service goes into more detail about why:

"DO Non CAN spaghetti squash. Its flesh does not stay cubed during processing. Spaghetti squash tin be frozen." ^[four] Andress, Elizabeth and Judy Harrison. Preserving Food: Canning vegetables. University of Georgia. March 2013. FDNS-E-43-iii. Page half dozen.

The result is density. The spaghetti squash would interruption downwardly into a compacted mass, preventing full heat penetration to kill any botulism spores present.

Even if canning were possible, the resulting quality would be unacceptable. Strands of spaghetti squash need to exist at least slightly "al dente" to exist usable as "spaghetti", and if reduced to a fibrous moosh, most people would find the texture later on canning unpalatable.

Wash well before peeling

Penn State Extension says that the rinds of pumpkin and wintertime squash potentially take a lot of surface bacteria and other spoilage organisms:

Information technology is necessary to wash them thoroughly before taking a knife through the skin which could force surface bacteria down into the flesh. Scrub them with a vegetable castor nether cool running h2o before cutting and cooking. Do not use soap or detergent." ^[5] Ibid.

Expert winter squash for home canning

It's unfortunate, admittedly, that winter squash has to exist peeled and cubed earlier canning. Beingness able to roast or pressure can a squash, then just scrape the soft flesh off the skin and into jars certainly would be a lot less piece of work than peeling raw squash.

But given that that'south the reality, it'southward no pocket-size wonder that and then many habitation canners prefer working with butternut squash (or even ameliorate, one of the straighter variants such as Waltham butternut squash.) It's pretty much the easiest winter squash to peel attributable to having the fewest ridges. Squash such equally acorn squash is a beast to peel. Information technology'south almost better to roast that, scrape off the mankind, and freeze in tubs.

Waltham butternut squash is possibly the easiest squash to peel when raw.

Waltham butternut squash is maybe the easiest squash to skin when raw.

Prep tip

If you are canning slap-up quantities of apparently squash, it can be onerous to try to peel, chop and procedure all in one day, especially given the long 90 minute processing times for the litre / United states quart jars.

Yous may wish to consider on i day doing the peeling and chopping, and so storing your raw squash cubes in the refrigerator overnight in sealed bags. The next solar day, accept out of the fridge virtually an hour earlier starting to let them warm up to room temperature, so proceed with the blanching.

It makes for a less grueling session.

Pickling Pumpkin and Squash

The National Center for Home Food Preservation says that, in their arsenal of canning recipes, they don't accept any recommendations for canning pickled pumpkin or winter squash:

Pickling Pumpkin: Pumpkin can be used in pickled recipes such every bit salsas, chutneys, and relishes; all the same, your recipes for these must be treated as fresh prepared foods and kept refrigerated. We do not have tested recipes and procedures to recommend for safely canning these types of products by either the boiling water or force per unit area canning method." ^[6] Andress, Eastward.L. Domicile Preserving Pumpkins. Athens, GA: The Academy of Georgia, Cooperative Extension Service. 2010. Accessed July 2015.

Other reputable sources, however, practise have some recipes for pickling winter squash, and pumpkin.

History

The first recommendation nigh squash was really not to can it at all, simply rather to keep it in a root cellar: "It was recommended that beets, carrots, mature lima beans, pumpkin and squash should non exist canned since root vegetables could exist stored satisfactorily and drying was possible for lima beans and okra." ^[seven] Andress, Elizabeth Fifty and Gerald Kuhn. Critical Review of Home Preservation Literature and Current Research. 2. Early History of USDA Abode Canning Recommendations. Athens, GA: University of Georgia, Cooperative Extension Service. 1983.

By 1936, y'all could can it, though they wanted it canned at 15 lb force per unit area: "In September 1936, Farmers' Bulletin No. 1762 … was issued…. Some vegetables – greens, pumpkin, squash and foam-fashion corn – required a 250F (15 psig) processing temperature." ^[8] Ibid.

Older canning books contained USDA directions for canning mashed squash and pumpkin. Here are 1947 directions for puréed:

mashed-squash

Click to enlarge. From: Tanner, F.W. and Grace B. Armstrong. Canning Fruits and Vegetables. Circular 614. Urbana, Illinois: University of Illinois Extension Service. June 1947.

In 1978, a University of Minnesota team headed by Edmond Zottola re-evaluated that canning recommendation and establish it was potentially unsafe:

Another interesting issue studied by Zottola et al (1978) was the safety of canned strained (pureed) squash or pumpkin using current recommendations. Diverse product viscosities from the same recipe yielded a wide range of F0 values. The authors recommended canning cubed pumpkin or squash only since heat penetration data for this product were more uniform than for strained. This effect perhaps requires a conclusion on a standardized policy regarding recommendation for canning strained pumpkin." ^[9] Andress, Elizabeth Fifty and Gerald Kuhn. Critical Review of Home Preservation Literature and Current Research. 3. Origins and Cess of Current USDA Recommendations BHNHE and Related Research. Athens, GA: University of Georgia, Cooperative Extension Service. 1983.

This led to the USDA withdrawing its recommendations for mashed squash and pumpkin and since 1989, the recommendation has been to can in cubes. ^[10] Andress, Elizabeth. "History, Scientific discipline and Current Practice in Abode Food Preservation." Webinar. 27 February 2013. Accessed Jan 2015.
