Delicious Grilled Prawns - cooking recipe

Ingredients

1 kg prawns (try to use queen or big ones always better for grilling)
125 g butter (no substitutes)
10 ml freshly crushed garlic
1 tablespoon tomato paste
5 ml red chili pepper flakes (use more if you like it hotter the original recipe has 10ml)
1/2 teaspoon black pepper
salt
25 ml mayonnaise
25 ml chili sauce
15 ml lemon juice

Preparation

Wash and devein prawns but retain the shell. Retaining the shell makes it more tasty. Dry prawns well.
Melt butter and add the garlic to to it; mix well.
Add rest of the ingredients to butter mixture except prawns.
Marinate the prawns in HALF of this marinade for several hours. 2-4hrs is sufficient. (I sometimes add all the sauce if I want it saucy).
Place prawns in oven tray and grill till done on 180\u00b0C tossing them at intervals.
Heat the rest of the marinade until thickens into a sauce pour some of the sauce over the grilling prawns and use the rest as a dipping sauce for prawns. Serve hot. Serve with savoury rice and a salad. You can also substitute prawns with shrimp.
