Oopsie rolls from online

Line baking tray with greaseproof paper and put the oven on to 150°

Put egg yolks, cheese & salt in a bowl and whisk on low until creamy and smooth

In another bowl whisk egg whites and cream of tartar until stiff like meringue

Carefully fold the whites in dollops into the yolk mix rotating the bowl. I did this in 4 stages.

Put 6 big dollops onto the tray and press down slightly with egg spatula

Put in oven and cook for about 30 minutes until golden brown then cool for few minutes before transferring to wire rack.

Butter the flat sides and make sandwiches

Enjoy...
