Now take the four garlic cloves and chop them up then sprinkle with some salt and using the back of a large knife smash the garlic up until it forms a paste.
Then place the garlic with some olive oil in a frying pan (skillet) and cook over a medium to low heat until the garlic starts to turn brown.
This should take around 5 minutes then once the garlic has turned brown remove from heat.
Next you take the shrimps and thread them onto wooden skewers and sprinkle over them some salt and pepper to season.
Then brush one side of the shrimps with the garlic and olive oil mixture you made earlier and place this side down on to the barbecue.
Cook the shrimps until they start to turn pink in color and they begin to curl.
This should take around 4 minutes and then turn them over.
But before placing back down on the barbecue brush with more of the garlic oil and then cook for a further 4 minutes until the flesh has turned opaque and the shrimps are pink all over.
