Place a frying pan or plancha over direct heat
in your outdoor cooker or on top of your hob
and get it hot. Drizzle in some oil and
chuck in a knob of butter (if you like). Throw in
the onions and mushrooms and sprinkle over
the brown sugar. Slowly cook down until soft –
at least 10 minutes – then push to one side.
Season the mince with salt and pepper. I like to
add a pinch of garlic and onion granules for extra
flavour and a pinch of cayenne for kick. Mix well.
Divide the mince into four balls and flatten each
ball into a patty. There will be shrinkage when
the fat renders, so make them at least one-third
bigger than the buns. Place the patties onto the
heat and hit ’em hot. Flip ’em after a couple of minutes to work the other side.
In the meantime, toast your burger buns on
the grill, then put the bun tops face-down in
the onion and mushrooms mix.
When the burger has a nice brown crust on
both sides, it’s time to cheese. Lay a couple
of cheese slices on each patty and then place
your cloche (or large metal bowl) over the pan.
After 20–30 seconds (or when the cheese starts
melting) sprinkle or spray a little water next to
the burger and quickly replace the cloche. This
is the key to making this the best burger ever!
You only need to leave the cloche on for another
10–20 seconds to achieve ultimate steamy
squishy goodness.
Hit the bottom buns with a handful of iceberg
lettuce. Burger. Onion and mushrooms. Other
burger. A couple of pickle slices will always send
the burger to tasty town! Top bun. Now you’re
ready to indulge!
