Grandmother used to take an enamelled pot to a forest clearing where raspberries always grew. She packed these into the jar, so there was juice up to the neck. At home, everything was strained through a juicing grinder, then into the pan, sprinkled with sugar and the froth was collected. The whole kitchen smelled of raspberries. Don’t miss her recipe; it’s great on waffles and pancakes.
