I had this problem the other day after we got back from our holidays.
I put the old thinking cap on and found a tubberware lid that you have to press in the middle to seal properly. Our sink hole is big, central and in a bit of a dip. I placed the plastic lid over this and gave it a few "plunges" and it worked fine, caused a little bit if splashing but did the job.
Try some hardish plastic with a bit of a give in the middle if that's described ok???

Basically anything which will casue a bit of a vacume and "pump" out the lodged food/etc. from the pipe will work for this. So a hand, piece of plastic, whatever will cover the hold and allow you to pump a little to drag the lodgement up.
