Make the lemon lime vinaigrette first whisk the lime zest chili pepper flakes black pepper lemon juice honey and olive oil together set aside next arrange thinly sliced or cubed mango and avocado on serving plates or on one large platter cook the prawns.

A ratio is just a baseline maybe you prefer a very sharp vinaigrette with just two parts oil if you use lime juice as your acid you may need more than 3 parts oil i think the standard 3 to 1 though is just right.
