Flour or cornstarch?

Which would you rather use and why? I was just curious because I was looking at slow cooker pot roast recipes--yep, guess what's for dinner around here tonight--and flour seems to be the thickener of choice about half the time in the gravy, cornstarch the other half, so I was wondering why. I have both on hand. Flour is called for in the particular recipe I'm using, so I guess I'll go with it, but it just got my brain going as to why one would be chosen over the other.

  • I only use cornstarch to thicken in the crockpot. Flour needs more time to cook and lose it's flour-y taste, whereas cornstarch is ready to go minutes later.

    That site gives a good explanation.

  • I only use flour, but I also don't do crockpot gravy. We always start with a roux.

  • Yeah, I'm with NotPanicking, I don't thicken it in the crockpot, I wait and make a gravy when it's finished cooking...

  • I personally prefer cornstarch because I get more consistency with it. I don't know what I do wrong with flour, but whenever I have used it my gravy seems really clumpy.

  • I think flour thickens a little slower- more ideal for a crockpot, where as cornstarch thickens quick and needs a bit more attention.

  • Flour can stand up to more cooking that cornstarch can, so with a slow-cooker recipe where it's going in early on, you probably NEED to use flour. Cornstarch also turns clear and has a glossy appearance that people generally don't expect with something like a stew.

  • For thickening, I prefer cornstarch. It's too easy to add too much flour and ruin the gravy, or make it lumpy.

  • since its crockpot, id go flour. personally, i like cornstarch better for thickening sauces (never gravies) cause its smoother, but thats only when im gonna be standing right over it.

  • I use flour, but then I'm a gravy girl, not so much a maker of white sauces and the like. Toasted flour (browned lightly in a heavy dry pan) is the best!
