Clear Jel vs Flour or Cornstarch
Clear Jel..... try it you'll like it!
I used to can apple pie and other pie fillings with flour or
cornstarch as a thickener.... I'd heard of this product but I had not tried
it. It has been on my list of things to do.
Well I've gone and done it. And I am sold.
If you'll look at these pictures you'll see why. These are both
apple pie fillings that I've canned. I'll bet you can tell which one
has flour as a thickener. Yep the one on the left. The right one is much nicer!!
Clear Jel is a modified corn starch made to withstand the heat of canning. Use it just like you would flour. The wonderful difference is... it stirs in much easier and no clumping. Be sure you purchase the non-instant or regular type. The regular is made to withstand the high temperatures of canning.
Instant will not hold up. It is good for using in gravies and other non-canning thickening.
2nd and probably most important reason to use clear jel.
Flour and/or cornstarch even tapioca may be a safety risk. All extension websites don't mention this risk, most only relate the quality issues. However there is at least one extension does have this to say.
"Canning apple pie filling using tapioca or cornstarch as the thickener is an outdated and risky method. Botulism is not a major risk with this product because of the high acid content of the apple filling. However, using cornstarch or tapioca may cause the filling to be too thick for the heat to penetrate to the center of the jar and kill spoilage organisms throughout the product, which is a food safety issue. Cornstarch and tapioca will also break down during the canning process and your pie filling will be runny which is a quality issue."

Where to buy Clear Jel
Clear jel can be hard to find sometimes. It often be found in Old Fashioned or Amish type stores. Or possibly in health food stores. It can also be ordered online at Amazon.
What if I can't find it?
If you don't have access, your best bet is to just can the fruit and create your filling by thickening it when you want to make your pie.

Question: Hi! I love your website! I'm new to canning and gardening but am
having a lot of success this year! I wanted to try your apple pie
filling method but am having trouble finding Clear Jel in my grocery
store or Walmart. Do you recommend ordering online or do you have any
Answer: It can often be found in Old Fashioned or Amish type stores. Or

Be sure you get the non instant type. It is best for canning.
Read Mitchells e-mail below to learn more. She is the person who introduced me to clear jel.
I just read the question on pie fillings, you did not know what special pie thickener that the person was talking about.
It is called Clear Jel, you would buy the "Cook Type" it is a specially
modified cornstarch that does not break down like regular. cornstarch or
As for buying it you can find it the cheapest if you live in an area
that had Mennonite or Amish Bulk Foods, there it runs about 2.00 per lb.
on line you can find it but they rob you at 6.00 per lb.
Believe me once you get to using it, you will never go back to reg.
cornstarch again. I mean for reg. cooking, homemade custards etc.
I wanted to tell you also, that the one nice point on the "Cook Type"
(there is an instant type) you don't want that, you want the "Cook Type"
Is that when you use this, when you thicken your pie fillings custards
etc. It gets as thick as it is going to get when it is hot in the pan,
so what you see is what you get, so you know that your pie fillings in
the jars is going to be as thick when you open and dump them out as they
when they went into the jars.
You know when you make Cornstarch Custard at home for dinner, and you
use corn starch how when it went into the bowl looking nice, then when
it got cold and you could cut it like jello (what a disappointment) Well
Clear Jel, takes care of that, the way it was in the pan is the way it
will be in the bowl out of the fridge.
You will love it, mix it up as your thickening just like using reg. cornstarch.
Question - Can I ask you if it is safe to use cornstarch as a thickener when canning (say apple pie filling).. and do you know if Sure Gel and Clear Gel are interchangeable?
Answer - Sure Gel is a pectin. You use it in jams and jellies. Whereas clear jel is what you want for pies.
NCFHFP standards do not recommend flour or cornstarch, but most state extensions don't really state that it is
for safety. However there is one extension at least that DOES indicate a safety issue. Clear Jel really is
sooo much nicer. I highly recommend it.
And the safety issues are discussed here at the University of MN

Question: I am having problems with my pie filling holding it's jell after I have
canned. I canned some blueberry pie filling last year and it was great
when I put it in the jars. But when I used it nine months later it was
runny when I opened it.
When I make a pie I use a gram cracker crust and
heat it up at 350 degrees for 45 minutes. It stays runny. I have added
Clear Jel to thicken it up when it comes out of the jar and it has
helped. But I give away the pie filling to my kids and they don't use it
because it is so runny. HELP!
Answer: Duane, The only thing I can think of is maybe you need to use
a bit more. I've not had any issues like this so possibly your
personal taste is that you like it thicker. Be sure and measure
carefully when you make your filling.
I have read reports of setting up issues if it is too old. Is yours out of date?
One last possibility... did you use an instant? Or the regular. Remember instant won't hold up as well. That may be the issue.
Only other thing I can suggest is change the label on the jar to... blueberry syrup. :) Great over ice cream or pancakes. :)
