Check out our glass crock pot lid selection for the very best in unique or custom, handmade pieces from our shops. ..

Add more liquid. If it is still getting too hot, check to see if it has a temperature knob on it somewhere, if not, you can release some of the heat by removing the lid slightly to let steam and heat release from it as it cooks

turn crock pot a little more down wile cooking and add a little more water to what your cooking with a little oil to the water.

Well, that all depends on how dense a sloppy joe mixture you make. If you add pounds and pounds of ground beef to the mix and just the sloppy joe sauce, then it would be many pounds.

But as for a good rule of thumb, "A pints a pound the world around" In other words, if you're making sloppy joes from the pre-mixed cans, just weigh one 16 oz (1 pint) can and that's 1/2 quart.

If you're making it yourself, we're back to the whole density of your chosen ingredents.

However, I've done a little research for you and based on the density of cooked beef and converting the weight of that cooked beef into the 5 quart volume of your crockpot, I've come up with the following info for you.

Cooked Beef has a density 129.52 Ounces per Gallon (a technical measurement)

So based on that data (not including your sloppy joe seasoning/sauce and other add-ins), you should get approximately 10.12 Pounds of Sloppy Joe Mixture to fit into your 5 Quart Crockpot.

I would guess that the amount would be just slightly less, since you might want a little room for putting on the lid, etc., but you should get around 10 Pounds to fit easily in your 5 quart crockpot.

I hope you find this Very Helpful and best regards!

I have another pot with a lid and the lid 'fits' my crockpot; my glass crock pot just broke and my heart broke along with it! The cooking pot's lid worked for the soup I made last week but you can't see into the pot; I like that about the crock pot. Try another lid, or you can try to buy a new/different one, like I'm trying to do! :)

the gaskets are junk , i had to toss one myself i used one time then stored for a year and the gasket went bad , mine came from hsn when i called them ,there where no parts made for it . so out it went cheep china junk . sorry , good luck

I am Jo Anne Gomez who posted original problem and thought the problem was resolved with husband putting on a knob he found at the hardware store. Just wanted to let you all know that the handle we thought would solve the problem DID NOT....after he replaced the knob and we did another roast in it the lid totally shattered after we'd cooked another roast (luckily the glass did not get into the food), however, this is just a BAD PROBLEM and these lids should ALL be recalled. I have seen, just recently, the exact same crock pot and lid being sold for much less. I think that these crock pots should not even be sold but taken off the market to prevent lawsuits or horrible problems. Just wanted to let you know our solution did not work and Rival was not helpful at all.

Most of the reviews for this product state that the lid is a bad fit. It is as though they had leftover lids from another model and just used them in this one. A replacement lid will be the same unless you have one custom made...but for that price you'd just get a new crock pot. You will lose a lot of moisture and some foods will be a little dried out after slow cooking all day and losing steam. You can either cover the cracks as best you can when you set it to cook, or return it and buy a better model. You'll find this problem on Rival's 6 quart crock pot as well. Read the reviews before you make your next purchase.

hhh

You should keep the lid on as much as possible. You are correct; once you open the lid, the liquid inside can quickly lose temperature at a rate of 10-15 degrees per minute.

Additionally, taking the top off allows steam to escape, which reduces the point of cooking in a slow cooker (cooking in a relatively closed system, with the steam condensing back to water and flowing back into the broth).

It's not doing a whole lot to the flavor (aside from causing the stew to thicken with the loss of water), but it is definitely causing the cooking to take longer than it should.
