This is a savoury cold dish using egg white foam to create a ‘wrap’. It shows how coagulation of egg white protein can be used creatively. The term roulade originates from the French word ‘rouler’, meaning ‘to roll’.

 

Recipe Science

Cooks Know How:  This classic dish shows how egg white foam can be cooked gently to make a layer that can be filled and rolled like a ‘Swiss roll’.  The heat of the oven sets (coagulates) the proteins in the egg white so that they become firm yet bendy.  Cooling the cooked egg layer under a damp tea towel ensures that it will roll up without cracking. The addition of the egg yolks after the foam is created provides the attractive yellow colour and adds iron and more protein.

The filling uses cooked tuna to provide more protein.  Seasonal avocado provides colour and texture.  Remember to use some acid lemon juice to prevent the avocado from browning due to enzymic action once you cut it up.  Seasoning is an important skill to get the dish really tasty.

Spread the filling over the egg layer and use the damp tea towel to gently roll up the roulade.

Using a sharp knife trim off the ends of the roll to neaten.  Chill in refrigerator.
