Unfortunately, I can't find my Mother's recipe. I know I have it somewhere, but.... However, I found one in my old 1938 Five Roses Cook Book. Here they're called French Pancakes. Maybe it's similar.

Beat egg yolks until thick and lemon coloured; add sugar and 1/2 cup milk. Stir in flour with remaining milk and melted butter. Beat egg whites until stiff but not dry; fold into batter. Drop by 1/3 cupfuls on hot pancake griddle. Cook pancakes until they are filled with bubbles and the under surface is golden brown. Turn and brown the other side. Spread with jelly or sugar and lemon or whatever, roll up and enjoy.

Btw, I've had trouble responding to the group, (not sure why) so if this comes back to me, I'll send it on to you personally. And I'll also have another look around for my Mother's recipe.
