Buying food stuff in large quantities is one of the best ways to save money.
Here are a few tips to help you save money by buying and storing crayfish for a long time.
Put the crayfish in a tray and sun dry for a few days depending on the quantity.
Then sieve the crayfish to remove chaff. Note that the chaff is not useless, as you can still use it to cook.
Then put the crayfish in a frying pan and fry in a very low heat for about 10 seconds and allow to cool.
Then put in a container and store in a cool dry place.
