Can I grind whole bean coffee in the food processor?

I bought a 3 lb bag of coffee at Costco and forgot to grind it on the way out. (I hate it when that happens!) Can I grind it in the food processor. If so, any tips?

    It works better in a blender, a cup at a time....or yes, you can buy a coffee grinder which works a few beans at a time.....or bring it back to Costco and have them grind it....or if you're near an A&P, ask the store manager if you grind it in one of their machines....they'll probably say yes if you buy something too......We've all forgotten to grind the coffee; it's no big deal. Let me tell you about the time I bought the fish at dockside and forgot to ask them to remove the scales!

        When you mention "in a blender", are you refering to Oster type blenders? I have not tried grinding coffee beans in mine but if it works I like the idea of doing more beans than in a grinder.

          I know several people do soybean in blenders. I have never done it.

            Many years ago I had an Oster blender and it came with a couple of 1 cup sized containers which attached to the blender and they were meant to be used to grind or chop things like coffee beans, nuts and other stuff.

          No.

          Get a Krups for 19 bucks: http://www.amazon.com/Krups-203-42-To...

            Get yourself a little inexpensive coffee grinder. We've had a little Krups for longer than I can remember (under $20). Then you can have freshly ground coffee whenever you want it and can buy some interesting beans when you find them and store them in the freezer if you need to for longer than you would be able to keep ground coffee. Life is short; get a grinder.

              Ok, y'all convinced me. I was just trying to avoid a return trip to Costco on Superbowl weekend, but if I gotta go I gotta go! Thanks for all of the good info & warnings.

                Grinding at the store is just as ridiculous as grinding it in a food processor. Those coffee beans you pre ground will go stale in 15 minutes. Picture a sliced apple on your countertop and count the minutes until it starts turning brown.

                  You can just take it into any supermarket that has a grinder and do it there. If the cashier asks why you have it in your cart, just tell him/her. Chances are s/he won't care and it's easier to get forgiveness than permission. I've done it with a one-pound bag that fit into my handbag. Another time, I took the beans to a Dunkin Donuts that I frequent and asked the clerk if she would mind grinding it, which she agreed to do without hesitation.

                    Especially recommended if you crave a healthy dollop of stale coffee grounds from the store machine in your otherwise fresh coffee. Hopefully your grocery store doesn't profile people with pound bags of coffee in their purses as suspicious.

                  I tried this once when my grinder conked out. All I can say is DON'T. The coffee never got fine enough to extract a decent brew.

                  Get a grinder or take it back.

                    Hi nojunk,

                    I won't do it for many reasons. First, you cannot really do it effectively. By design a food processor is not meant to grind food finer. It is designed to chop coarsely. Second, it hurts the food processor blade. Third, coffee beans favor will linger in your food processor for a long while. It is best to use a coffee grinder.

                      Coffee beans are not harder than food processor blades (they BETTER not be, as that would be a serious defect in the blade), so they won't hurt the cutting edge at all ...but should they get wedged under the blades, I suppose they could bend them a little.)

                      Blade damage isn't the biggest risk here...having half-ground meal because the blades spin higher than a bean resting at the bottom of the work bowl is.

                      I've done that -- take it back in with your receipt...they'll chuckle and let you go back and grind it.

                        Go ahead, especially if you're curious what grinding a box of wood screws sounds like in your fp. Besides, it really doesn't work. Get a cheap blade grinder.
