Butter a griddle or heavy frying pan and heat up. Butter poaching rings and set in the pan. Cook crumpets over a medium heat by adding 1 or 2 tbsp of batter at a time to each poaching ring. When the top is set remove the ring and turn the crumpet over and cook for 2 or 3 minutes more. In the meantime, the ring can be re-buttered and used for the next ones.
Serve hot with butter, or with jam.
