Yesterday was my first time pressure-canning veggies. I made mashed squash baby food for The Squidgy and I think it worked pretty well. There was no information on this on the internet so I made it up using the best of my safe-canning knowledge.
Squidgy Squash
1. Peel and cube the squash. Any winter squash is fine. I used three Kubota squashes that I got from the local produce market.
2. Put the squash in a saucepan that is about twice as big as the volume of squash. Put enough water in the pot to cover about half the squash. Put the lid on. Bring to a boil over high heat then reduce to a simmer. Cook until the squash is quite tender.
3. While the squash is cooking heat up clean jars, rims and lids in nearly boiling water. I used 125mL jars as they are the smallest available but still use the standard size mason lid. Fill up the kettle and boil it.
4. Drain the squash and return it to the same pot. Return the pot to the hot burner but turn the heat down to low. Mash the squash and keep it moving in the pot so it doesn’t burn. Make sure the squash is kept as hot as possible without burning it.
5. Pull the jars (or half the jars if you are working with more than four jars), lids and bands from the hot water. Fill the jars with the hot squash to within 1cm of the top for the 125ml jars. Headspace for 250ml (half-pint) jars is about half an inch and for 500ml (pint) jars leave an inch. Do not pressure-can squash in quarts. Clean the rims with clean, wet paper towel. Center the lids on and put the screw bands on finger-tight only. Put these jars in the pressure-canner and put some of the boiling water in the bottom of the canner to keep the jars warm. If you are doing more than four jars repeat for the remaining jars.
The idea is to keep the contents of the jar and the jars themselves as hot as possible all the way from cooking through filling and processing. Squash and other veggies with high starch content expand a great deal when they are hot. If you pack the jars with less-than-boiling squash it will boil out in the canner and make a big mess. The squash is still perfectly good as long as the jars seal but the cleanup is a total pain as the sugars dry on to the inside of the canner and the jars with amazing stickiness.
6. Add more boiling water to the canner until there is about an inch and a half of water in the canner. I use an All-American Pressure Canner so the rest of the instructions are for this type of canner only. (In my estimation it’s the absolute best one.) Put the lid on the canner but don’t put the pressure weight on yet. Put the canner on the stove and turn the heat up to high. When the water boils start timing and allow the canner to vent for seven minutes. I use a small burner on the stove because a large burner will apply too much heat during the actual pressure canning. After the water boils I turn the element down to medium-low to keep it boiling while it vents. I know the water is boiling because I can hear it! I put my ear next to the bottom of the canner and the bubbling can he heard quite distinctly.
7. Add the pressure weight and use the 10lbs setting. Stand by the stove and watch the pressure gauge. This is not the time to get something else done. When the pressure reaches 10lbs (or 8-12lbs as the manufacturer specifies) start timing the canning. Processing times are: 50 minutes for 125ml jars, 65 minutes for 250mL jars and 80 minutes for 500mL jars. Now I fiddle with the burner temperature until the pressure weight sputters one to four times per minute. This part is just about knowing your stove and your canner. On my stove this is one setting higher than absolute low. It doesn’t take much energy to keep the water boiling and the pressure up once it’s rolling.
8. When the time is up turn off the element. Wait until the pressure reading is totally zero before you take the weight off. Open the lid AWAY FROM YOU. My jars are usually already sealed before I even get the lid off. If not they seal within a few minutes. I don’t mess around with non-acid foods – if they don’t seal throw them out. I don’t try to re-process them, it’s just not worth the risk.
So far I have processed seven 125mL jars of the squash and I think I have about seven more to go. My canner is so small that I can’t stack the jars so my batches are small. It’s okay though, I love my canner and it’s so small that it’s easy to store in an apartment. This was my first time canning non-acid foods and it was super easy. I hope Morgan likes Kubota squash. I have to admit it didn’t smell all that good in the kitchen while it was canning but I think that’s because some of the squash boiled over and was being steamed pretty violently. It tastes pretty bland but I hear babies don’t get much of a choice with the foodz so I know she will eat all of it.
I would definitely consider canning my own pumpkin this year for pies and cheesecakes. Yummmmm…. pumpkin cheesecake….
Friends! Want to use the pressure canner? Call me! I would love to show you how.
