Notes
Tips for the BEST Chilli Garlic Prawns
Use Fresh or Frozen Prawns - It is easy to get good quality frozen prawns these days. I love the 12 in Shell Madagascan Prawns from M&S.
Pat the Prawns dry - When using either fresh or frozen prawns, pat them dry before cooking them.
Devein Prawns - Watch this video on how to devein prawns without removing the head.
Do not microplane or press the Garlic - I have touched on the before in another post but in some cases, (especially when the cooking time is so short and the heat is so high as is the case here), micro planing or crushing garlic causes it to burn leading to an acrid flavour.
Cook a few at a time - It is tempting to shove all the prawns in the pan together but this forces the temperature of the oil/butter down and then the prawns are steaming rather the frying. Which means they won't be as delicious!
Do not overcook them - Prawns need very little time to cook. I wouldn't go for any more then 2 - 3 minutes per side. Overcooked prawns are tough, rubbery and just not very nice.
Cook over high heat - We want to sear the prawns so high heat is crucial.
Use Oil as well as Butter - Butter adds somuch flavour but it burns at high heat. Adding Oil stops that from happening.
How to serve these Prawns
Adding extra butter towards the end of cooking time creates the most divine sauce which you can mop up with any bread such as this No Knead Bread.
