I agree that special wet chemical is the best type for kitchens, as it is
also effective on solid fires. However, it costs over 150 quid a pop, so
is
unlikely to make inroads into the domestic market.

Actually, the following supplier appears not only substantially cheaper for
the real McCoy 6kg, but seem to sell a small domestic wet chemical version
that looks like an alternative (or supplement) to the fire blanket.

It's only 15 quid (and 600g), but that should be enough to enclose a chip
pan. With a 3A rating, it might even put out a cigarette! However, I'd be
worried about how to apply it without disturbing the pan. There appears to
be no lance from the picture.
