Bucket of hot water and a brush. Brush water onto adhesive and leave for 20 minutes or so. This will soften the adhesive and then you will be able to scrape it off with a decent scraper. You may need to brush on a couple of times.
If you haven't got one, buy a long handled scraper that takes what looks like an over sized Stanley blade. Once adhesive has softened enough it will scrape off like butter, only not yellow.

Re: retiling over old tile adhesive
That will work if its dispersion adhesive (ready mixed) but not if its cement based. A good scraper and plenty of elbow grease is what you need.

Re: retiling over old tile adhesive
well the sister went and tiled over the old adhesive
so its like a moto cross track! grouted and all
so theres a 11mm gap between bottom line of tile and worktop one end
and 2mm the other end!... so goin to silicone the gap as i'm told that grout would just crack
with movment in a wooden worktop
so the question is which silicone?

Re: retiling over old tile adhesive
I would have thought the differing gap is due to the worktop or tiling or both being out of level. The gap at the junction of worktop and tiles should always be siliconed as its a movement joint. Even if the worktop is granite. If white, I use Dow Corning 785 sanitary silicone, Mapei if I want a coloured one.

Re: retiling over old tile adhesive
scrape it off. Tiling is hard enough as it is, try make the task as painless as you can.

With a difference in tile / worktop join like that I'd cover it with a length of upvc quadrant / beading.
And 11mm silicone bead will not look good for long - even if you use Dow Corning.
Nice bit of quad will hide the gap nicely.

If at first you don't succeed - remove all evidence that you tried.
