Roast a head of garlic with a little olive oil and salt on top, wrapping it in foil and baking for 40 mins at 400 degrees.
Mix the mayo, garlic, truffle oil and salt together in a small bowl. Set aside.
Heat your oven to 350 degrees.
Prepare your prawns by thawing them, peeling them and de-veining them if need be.
Line a baking sheet with tin foil and spread the bacon pieces out on the sheet. Bake the bacon for about 8 mins till its cooked but still pliable. You dont want it crispy here!
Remove from the oven and place bacon on a plate lined with paper towel. Dab the fat off.
In a bowl, toss the prawns with the lime juice, cajun and seafood seasonings.
Line another tray with parchment paper or foil.
Wrap each prawn with a piece of bacon and secure with a skewer or toothpick and place on the parchment paper. Continue till all prawns are wrapped.
Cook in the oven for about 3 mins, flip them over and cook an additional 3 mins. The prawns should be bright pink and cooked through. If you need to, cut one open and check to see. They will be white all the way through.
