Aubergine
Aubergine
No thermometer needed. Salt it first, then go by softness.
On the grill
Slice it and salt it 20–30 minutes ahead if you have time. Salting draws out bitterness and stops the flesh soaking up excess oil once it hits the grill.
It is done when a knife or skewer meets almost no resistance in the centre, which usually takes longer than it looks like it should over direct heat.
