1kg waxy potatoes	cut into quarters or lunes		place into roasting tray lined with foil and parchment	Wrap up parchment and foil. Bake in very slow oven (135°C fan-assisted) for 5 hours.
optional other vegetables e.g. capsicum, bulb garlic
1 bulb garlic	chop garlic finely	make paste	place on top

1 lemon's juice			drizzle over

100ml dry white wine or water			pour in corner

Temperature and timings vary, from 140°C for 4.5 hours, to 170°C for 3 hours, to 180°C for 2.5 hours. My timing is off the low end of the range.

Sitting on top of the lamb, the tomatoes dry out and become concentrated.
