You can cook the prawns in the oven for 10-12 mins, they just may not go as golden.
Heat oven to 200C/180C fan/gas 6.
Arrange the chips on a baking tray,
drizzle with the oil and season. Bake
for 40-45 mins until golden, turning
Mix the prawns in the beaten egg
and tip the crumbs onto a plate. Lift
the prawns out with a slotted spoon
so that any excess egg drains off and
toss them in the crumbs with your
hands so they are coated. Transfer
to a baking tray.
When the chips have 10 mins to go,
heat grill to high. Cook the prawns for
3-5 mins each side, until crisp and
cooked through. Serve with the chips,
some tartare sauce and lemon wedges,
if you like.
