I know, the picture ain’t pretty, it was made in a hurry and I don’t think the bottom was cooked enough. But… it tasted good. Reminiscent of the bottom layer of the Lemon Surprise Pudding, but much quicker to make.
Basically you whisk sugar, the rind of a lemon and its juice with 3 egg yolks. Whisk the egg white until stiff and fold them into the yolk mixture. Cook quickly in a hot pan, then cook the top under the grill. Ready!
