_Mode_.--Prawns should be very red, and have no spawn under the tail;
much depends on their freshness and the way in which they are cooked.
Throw them into boiling water, salted as above, and keep them boiling
for about 7 or 8 minutes. Shrimps should be done in the same way; but
less time must be allowed. It may easily be known when they are done by
their changing colour. Care should be taken that they are not
over-boiled, as they then become tasteless and indigestible.
_Time_.--Prawns, about 8 minutes; shrimps, about 5 minutes.
_Average cost_, prawns, 2s. per lb.; shrimps, 6d. per pint.
_Seasonable_ all the year.
