In a pyrex dish mix together:

• 16 tablespoons of sugar
• 2 tablespoons of flour
• 1 oz melted butter

Then add:

• Finely grated rind of 2 large, juicy lemons
• 4 egg yolks
• All the juice of the 2 lemons
• 2 glasses of milk (about 1/3 of a litre)
• Beat the left over egg whites until firm, then mix in

Get a pan of water, put the pyrex dish in, then put the lot in the oven (like a bain marie) for about half an hour or until golden on top. Oven temperature should be at about 180c, depending on the oven!
